- * Changes:
- *
- * 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Amir Noam <amir.noam at intel dot com>
- * - Added support for lacp_rate module param.
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Based on discussion on mailing list, changed locking scheme
- * to use lock/unlock or lock_bh/unlock_bh appropriately instead
- * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
- * hidden bugs and solves system hangs that occurred due to the fact
- * that holding lock_irqsave doesn't prevent softirqs from running.
- * This also increases total throughput since interrupts are not
- * blocked on each transmitted packets or monitor timeout.
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Renamed bond_3ad_link_status_changed() to
- * bond_3ad_handle_link_change() for compatibility with TLB.
- *
- * 2003/05/20 - Amir Noam <amir.noam at intel dot com>
- * - Fix long fail over time when releasing last slave of an active
- * aggregator - send LACPDU on unbind of slave to tell partner this
- * port is no longer aggregatable.
- *
- * 2003/06/25 - Tsippy Mendelson <tsippy.mendelson at intel dot com>
- * - Send LACPDU as highest priority packet to further fix the above
- * problem on very high Tx traffic load where packets may get dropped
- * by the slave.
- *
- * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Code cleanup and style changes

* b: if a hw mac address already is there, eth0's hw mac address
* will then be set from bond0.
*
- * v0.1 - first working version.
- * v0.2 - changed stats to be calculated by summing slaves stats.
- *
- * Changes:
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- * - fix leaks on failure at bond_init
- *
- * 2000/09/30 - Willy Tarreau <willy at meta-x.org>
- * - added trivial code to release a slave device.
- * - fixed security bug (CAP_NET_ADMIN not checked)
- * - implemented MII link monitoring to disable dead links :
- * All MII capable slaves are checked every <miimon> milliseconds
- * (100 ms seems good). This value can be changed by passing it to
- * insmod. A value of zero disables the monitoring (default).
- * - fixed an infinite loop in bond_xmit_roundrobin() when there's no
- * good slave.
- * - made the code hopefully SMP safe
- *
- * 2000/10/03 - Willy Tarreau <willy at meta-x.org>
- * - optimized slave lists based on relevant suggestions from Thomas Davis
- * - implemented active-backup method to obtain HA with two switches:
- * stay as long as possible on the same active interface, while we
- * also monitor the backup one (MII link status) because we want to know
- * if we are able to switch at any time. ( pass "mode=1" to insmod )
- * - lots of stress testings because we need it to be more robust than the
- * wires ! :->
- *
- * 2000/10/09 - Willy Tarreau <willy at meta-x.org>
- * - added up and down delays after link state change.
- * - optimized the slaves chaining so that when we run forward, we never
- * repass through the bond itself, but we can find it by searching
- * backwards. Renders the deletion more difficult, but accelerates the
- * scan.
- * - smarter enslaving and releasing.
- * - finer and more robust SMP locking
- *
- * 2000/10/17 - Willy Tarreau <willy at meta-x.org>
- * - fixed two potential SMP race conditions
- *
- * 2000/10/18 - Willy Tarreau <willy at meta-x.org>
- * - small fixes to the monitoring FSM in case of zero delays
- * 2000/11/01 - Willy Tarreau <willy at meta-x.org>
- * - fixed first slave not automatically used in trunk mode.
- * 2000/11/10 : spelling of "EtherChannel" corrected.
- * 2000/11/13 : fixed a race condition in case of concurrent accesses to ioctl().
- * 2000/12/16 : fixed improper usage of rtnl_exlock_nowait().
- *
- * 2001/1/3 - Chad N. Tindel <ctindel at ieee dot org>
- * - The bonding driver now simulates MII status monitoring, just like
- * a normal network device. It will show that the link is down iff
- * every slave in the bond shows that their links are down. If at least
- * one slave is up, the bond's MII status will appear as up.
- *
- * 2001/2/7 - Chad N. Tindel <ctindel at ieee dot org>
- * - Applications can now query the bond from user space to get
- * information which may be useful. They do this by calling
- * the BOND_INFO_QUERY ioctl. Once the app knows how many slaves
- * are in the bond, it can call the BOND_SLAVE_INFO_QUERY ioctl to
- * get slave specific information (# link failures, etc). See
- * <linux/if_bonding.h> for more details. The structs of interest
- * are ifbond and ifslave.
- *
- * 2001/4/5 - Chad N. Tindel <ctindel at ieee dot org>
- * - Ported to 2.4 Kernel
- *
- * 2001/5/2 - Jeffrey E. Mast <jeff at mastfamily dot com>
- * - When a device is detached from a bond, the slave device is no longer
- * left thinking that is has a master.
- *
- * 2001/5/16 - Jeffrey E. Mast <jeff at mastfamily dot com>
- * - memset did not appropriately initialized the bond rw_locks. Used
- * rwlock_init to initialize to unlocked state to prevent deadlock when
- * first attempting a lock
- * - Called SET_MODULE_OWNER for bond device
- *
- * 2001/5/17 - Tim Anderson <tsa at mvista.com>
- * - 2 paths for releasing for slave release; 1 through ioctl
- * and 2) through close. Both paths need to release the same way.
- * - the free slave in bond release is changing slave status before
- * the free. The netdev_set_master() is intended to change slave state
- * so it should not be done as part of the release process.
- * - Simple rule for slave state at release: only the active in A/B and
- * only one in the trunked case.
- *
- * 2001/6/01 - Tim Anderson <tsa at mvista.com>
- * - Now call dev_close when releasing a slave so it doesn't screw up
- * out routing table.
- *
- * 2001/6/01 - Chad N. Tindel <ctindel at ieee dot org>
- * - Added /proc support for getting bond and slave information.
- * Information is in /proc/net/<bond device>/info.
- * - Changed the locking when calling bond_close to prevent deadlock.
- *
- * 2001/8/05 - Janice Girouard <girouard at us.ibm.com>
- * - correct problem where refcnt of slave is not incremented in bond_ioctl
- * so the system hangs when halting.
- * - correct locking problem when unable to malloc in bond_enslave.
- * - adding bond_xmit_xor logic.
- * - adding multiple bond device support.
- *
- * 2001/8/13 - Erik Habbinga <erik_habbinga at hp dot com>
- * - correct locking problem with rtnl_exlock_nowait
- *
- * 2001/8/23 - Janice Girouard <girouard at us.ibm.com>
- * - bzero initial dev_bonds, to correct oops
- * - convert SIOCDEVPRIVATE to new MII ioctl calls
- *
- * 2001/9/13 - Takao Indoh <indou dot takao at jp dot fujitsu dot com>
- * - Add the BOND_CHANGE_ACTIVE ioctl implementation
- *
- * 2001/9/14 - Mark Huth <mhuth at mvista dot com>
- * - Change MII_LINK_READY to not check for end of auto-negotiation,
- * but only for an up link.
- *
- * 2001/9/20 - Chad N. Tindel <ctindel at ieee dot org>
- * - Add the device field to bonding_t. Previously the net_device
- * corresponding to a bond wasn't available from the bonding_t
- * structure.
- *
- * 2001/9/25 - Janice Girouard <girouard at us.ibm.com>
- * - add arp_monitor for active backup mode
- *
- * 2001/10/23 - Takao Indoh <indou dot takao at jp dot fujitsu dot com>
- * - Various memory leak fixes
- *
- * 2001/11/5 - Mark Huth <mark dot huth at mvista dot com>
- * - Don't take rtnl lock in bond_mii_monitor as it deadlocks under
- * certain hotswap conditions.
- * Note: this same change may be required in bond_arp_monitor ???
- * - Remove possibility of calling bond_sethwaddr with NULL slave_dev ptr
- * - Handle hot swap ethernet interface deregistration events to remove
- * kernel oops following hot swap of enslaved interface
- *
- * 2002/1/2 - Chad N. Tindel <ctindel at ieee dot org>
- * - Restore original slave flags at release time.
- *
- * 2002/02/18 - Erik Habbinga <erik_habbinga at hp dot com>
- * - bond_release(): calling kfree on our_slave after call to
- * bond_restore_slave_flags, not before
- * - bond_enslave(): saving slave flags into original_flags before
- * call to netdev_set_master, so the IFF_SLAVE flag doesn't end
- * up in original_flags
- *
- * 2002/04/05 - Mark Smith <mark.smith at comdev dot cc> and
- * Steve Mead <steve.mead at comdev dot cc>
- * - Port Gleb Natapov's multicast support patchs from 2.4.12
- * to 2.4.18 adding support for multicast.
- *
- * 2002/06/10 - Tony Cureington <tony.cureington * hp_com>
- * - corrected uninitialized pointer (ifr.ifr_data) in bond_check_dev_link;
- * actually changed function to use MIIPHY, then MIIREG, and finally
- * ETHTOOL to determine the link status
- * - fixed bad ifr_data pointer assignments in bond_ioctl
- * - corrected mode 1 being reported as active-backup in bond_get_info;
- * also added text to distinguish type of load balancing (rr or xor)
- * - change arp_ip_target module param from "1-12s" (array of 12 ptrs)
- * to "s" (a single ptr)
- *
- * 2002/08/30 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - Removed acquisition of xmit_lock in set_multicast_list; caused
- * deadlock on SMP (lock is held by caller).
- * - Revamped SIOCGMIIPHY, SIOCGMIIREG portion of bond_check_dev_link().
- *
- * 2002/09/18 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - Fixed up bond_check_dev_link() (and callers): removed some magic
- * numbers, banished local MII_ defines, wrapped ioctl calls to
- * prevent EFAULT errors
- *
- * 2002/9/30 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - make sure the ip target matches the arp_target before saving the
- * hw address.
- *
- * 2002/9/30 - Dan Eisner <eisner at 2robots dot com>
- * - make sure my_ip is set before taking down the link, since
- * not all switches respond if the source ip is not set.
- *
- * 2002/10/8 - Janice Girouard <girouard at us dot ibm dot com>
- * - read in the local ip address when enslaving a device
- * - add primary support
- * - make sure 2*arp_interval has passed when a new device
- * is brought on-line before taking it down.
- *
- * 2002/09/11 - Philippe De Muyter <phdm at macqel dot be>
- * - Added bond_xmit_broadcast logic.
- * - Added bond_mode() support function.
- *
- * 2002/10/26 - Laurent Deniel <laurent.deniel at free.fr>
- * - allow to register multicast addresses only on active slave
- * (useful in active-backup mode)
- * - add multicast module parameter
- * - fix deletion of multicast groups after unloading module
- *
- * 2002/11/06 - Kameshwara Rayaprolu <kameshwara.rao * wipro_com>
- * - Changes to prevent panic from closing the device twice; if we close
- * the device in bond_release, we must set the original_flags to down
- * so it won't be closed again by the network layer.
- *
- * 2002/11/07 - Tony Cureington <tony.cureington * hp_com>
- * - Fix arp_target_hw_addr memory leak
- * - Created activebackup_arp_monitor function to handle arp monitoring
- * in active backup mode - the bond_arp_monitor had several problems...
- * such as allowing slaves to tx arps sequentially without any delay
- * for a response
- * - Renamed bond_arp_monitor to loadbalance_arp_monitor and re-wrote
- * this function to just handle arp monitoring in load-balancing mode;
- * it is a lot more compact now
- * - Changes to ensure one and only one slave transmits in active-backup
- * mode
- * - Robustesize parameters; warn users about bad combinations of
- * parameters; also if miimon is specified and a network driver does
- * not support MII or ETHTOOL, inform the user of this
- * - Changes to support link_failure_count when in arp monitoring mode
- * - Fix up/down delay reported in /proc
- * - Added version; log version; make version available from "modinfo -d"
- * - Fixed problem in bond_check_dev_link - if the first IOCTL (SIOCGMIIPH)
- * failed, the ETHTOOL ioctl never got a chance
- *
- * 2002/11/16 - Laurent Deniel <laurent.deniel at free.fr>
- * - fix multicast handling in activebackup_arp_monitor
- * - remove one unnecessary and confusing curr_active_slave == slave test
- * in activebackup_arp_monitor
- *
- * 2002/11/17 - Laurent Deniel <laurent.deniel at free.fr>
- * - fix bond_slave_info_query when slave_id = num_slaves
- *
- * 2002/11/19 - Janice Girouard <girouard at us dot ibm dot com>
- * - correct ifr_data reference. Update ifr_data reference
- * to mii_ioctl_data struct values to avoid confusion.
- *
- * 2002/11/22 - Bert Barbe <bert.barbe at oracle dot com>
- * - Add support for multiple arp_ip_target
- *
- * 2002/12/13 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - Changed to allow text strings for mode and multicast, e.g.,
- * insmod bonding mode=active-backup. The numbers still work.
- * One change: an invalid choice will cause module load failure,
- * rather than the previous behavior of just picking one.
- * - Minor cleanups; got rid of dup ctype stuff, atoi function
- *
- * 2003/02/07 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - Added use_carrier module parameter that causes miimon to
- * use netif_carrier_ok() test instead of MII/ETHTOOL ioctls.
- * - Minor cleanups; consolidated ioctl calls to one function.
- *
- * 2003/02/07 - Tony Cureington <tony.cureington * hp_com>
- * - Fix bond_mii_monitor() logic error that could result in
- * bonding round-robin mode ignoring links after failover/recovery
- *
- * 2003/03/17 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - kmalloc fix (GFP_KERNEL to GFP_ATOMIC) reported by
- * Shmulik dot Hen at intel.com.
- * - Based on discussion on mailing list, changed use of
- * update_slave_cnt(), created wrapper functions for adding/removing
- * slaves, changed bond_xmit_xor() to check slave_cnt instead of
- * checking slave and slave->dev (which only worked by accident).
- * - Misc code cleanup: get arp_send() prototype from header file,
- * add max_bonds to bonding.txt.
- *
- * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Make sure only bond_attach_slave() and bond_detach_slave() can
- * manipulate the slave list, including slave_cnt, even when in
- * bond_release_all().
- * - Fixed hang in bond_release() with traffic running:
- * netdev_set_master() must not be called from within the bond lock.
- *
- * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Fixed hang in bond_enslave() with traffic running:
- * netdev_set_master() must not be called from within the bond lock.
- *
- * 2003/03/18 - Amir Noam <amir.noam at intel dot com>
- * - Added support for getting slave's speed and duplex via ethtool.
- * Needed for 802.3ad and other future modes.
- *
- * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Enable support of modes that need to use the unique mac address of
- * each slave.
- * * bond_enslave(): Moved setting the slave's mac address, and
- * openning it, from the application to the driver. This breaks
- * backward comaptibility with old versions of ifenslave that open
- * the slave before enalsving it !!!.
- * * bond_release(): The driver also takes care of closing the slave
- * and restoring its original mac address.
- * - Removed the code that restores all base driver's flags.
- * Flags are automatically restored once all undo stages are done
- * properly.
- * - Block possibility of enslaving before the master is up. This
- * prevents putting the system in an unstable state.
- *
- * 2003/03/18 - Amir Noam <amir.noam at intel dot com>,
- * Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Added support for IEEE 802.3ad Dynamic link aggregation mode.
- *
- * 2003/05/01 - Amir Noam <amir.noam at intel dot com>
- * - Added ABI version control to restore compatibility between
- * new/old ifenslave and new/old bonding.
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Fixed bug in bond_release_all(): save old value of curr_active_slave
- * before setting it to NULL.
- * - Changed driver versioning scheme to include version number instead
- * of release date (that is already in another field). There are 3
- * fields X.Y.Z where:
- * X - Major version - big behavior changes
- * Y - Minor version - addition of features
- * Z - Extra version - minor changes and bug fixes
- * The current version is 1.0.0 as a base line.
- *
- * 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
- * Amir Noam <amir.noam at intel dot com>
- * - Added support for lacp_rate module param.
- * - Code beautification and style changes (mainly in comments).
- * new version - 1.0.1
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Based on discussion on mailing list, changed locking scheme
- * to use lock/unlock or lock_bh/unlock_bh appropriately instead
- * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
- * hidden bugs and solves system hangs that occurred due to the fact
- * that holding lock_irqsave doesn't prevent softirqs from running.
- * This also increases total throughput since interrupts are not
- * blocked on each transmitted packets or monitor timeout.
- * new version - 2.0.0
- *
- * 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Added support for Transmit load balancing mode.
- * - Concentrate all assignments of curr_active_slave to a single point
- * so specific modes can take actions when the primary adapter is
- * changed.
- * - Take the updelay parameter into consideration during bond_enslave
- * since some adapters loose their link during setting the device.
- * - Renamed bond_3ad_link_status_changed() to
- * bond_3ad_handle_link_change() for compatibility with TLB.
- * new version - 2.1.0
- *
- * 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com>
- * - Added support for Adaptive load balancing mode which is
- * equivalent to Transmit load balancing + Receive load balancing.
- * new version - 2.2.0
- *
- * 2003/05/15 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - Applied fix to activebackup_arp_monitor posted to bonding-devel
- * by Tony Cureington <tony.cureington * hp_com>. Fixes ARP
- * monitor endless failover bug. Version to 2.2.10
- *
- * 2003/05/20 - Amir Noam <amir.noam at intel dot com>
- * - Fixed bug in ABI version control - Don't commit to a specific
- * ABI version if receiving unsupported ioctl commands.
- *
- * 2003/05/22 - Jay Vosburgh <fubar at us dot ibm dot com>
- * - Fix ifenslave -c causing bond to loose existing routes;
- * added bond_set_mac_address() that doesn't require the
- * bond to be down.
- * - In conjunction with fix for ifenslave -c, in
- * bond_change_active(), changing to the already active slave
- * is no longer an error (it successfully does nothing).
- *
- * 2003/06/30 - Amir Noam <amir.noam at intel dot com>
- * - Fixed bond_change_active() for ALB/TLB modes.
- * Version to 2.2.14.
- *
- * 2003/07/29 - Amir Noam <amir.noam at intel dot com>
- * - Fixed ARP monitoring bug.
- * Version to 2.2.15.
- *
- * 2003/07/31 - Willy Tarreau <willy at ods dot org>
- * - Fixed kernel panic when using ARP monitoring without
- * setting bond's IP address.
- * Version to 2.2.16.
- *
- * 2003/08/06 - Amir Noam <amir.noam at intel dot com>
- * - Back port from 2.6: use alloc_netdev(); fix /proc handling;
- * made stats a part of bond struct so no need to allocate
- * and free it separately; use standard list operations instead
- * of pre-allocated array of bonds.
- * Version to 2.3.0.
- *
- * 2003/08/07 - Jay Vosburgh <fubar at us dot ibm dot com>,
- * Amir Noam <amir.noam at intel dot com> and
- * Shmulik Hen <shmulik.hen at intel dot com>
- * - Propagating master's settings: Distinguish between modes that
- * use a primary slave from those that don't, and propagate settings
- * accordingly; Consolidate change_active opeartions and add
- * reselect_active and find_best opeartions; Decouple promiscuous
- * handling from the multicast mode setting; Add support for changing
- * HW address and MTU with proper unwind; Consolidate procfs code,
- * add CHANGENAME handler; Enhance netdev notification handling.
- * Version to 2.4.0.
- *
- * 2003/09/15 - Stephen Hemminger <shemminger at osdl dot org>,
- * Amir Noam <amir.noam at intel dot com>
- * - Convert /proc to seq_file interface.
- * Change /proc/net/bondX/info to /proc/net/bonding/bondX.
- * Set version to 2.4.1.
- *
- * 2003/11/20 - Amir Noam <amir.noam at intel dot com>
- * - Fix /proc creation/destruction.
- *
- * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
- * - Massive cleanup - Set version to 2.5.0
- * Code changes:
- * o Consolidate format of prints and debug prints.
- * o Remove bonding_t/slave_t typedefs and consolidate all casts.
- * o Remove dead code and unnecessary checks.
- * o Consolidate starting/stopping timers.
- * o Consolidate handling of primary module param throughout the code.
- * o Removed multicast module param support - all settings are done
- * according to mode.
- * o Slave list iteration - bond is no longer part of the list,
- * added cyclic list iteration macros.
- * o Consolidate error handling in all xmit functions.
- * Style changes:
- * o Consolidate function naming and declarations.
- * o Consolidate function params and local variables names.
- * o Consolidate return values.
- * o Consolidate curly braces.
- * o Consolidate conditionals format.
- * o Change struct member names and types.
- * o Chomp trailing spaces, remove empty lines, fix indentations.
- * o Re-organize code according to context.
- *
- * 2003/12/30 - Amir Noam <amir.noam at intel dot com>
- * - Fixed: Cannot remove and re-enslave the original active slave.
- * - Fixed: Releasing the original active slave causes mac address
- * duplication.
- * - Add support for slaves that use ethtool_ops.
- * Set version to 2.5.3.
- *
- * 2004/01/05 - Amir Noam <amir.noam at intel dot com>
- * - Save bonding parameters per bond instead of using the global values.
- * Set version to 2.5.4.

- * 2004/10/29 - Mitch Williams <mitch.a.williams at intel dot com>
- * - Fixed bug when unloading module while using 802.3ad. If
- * spinlock debugging is turned on, this causes a stack dump.
- * Solution is to move call to dev_remove_pack outside of the
- * spinlock.
- * Set version to 2.6.1.
- * 2005/06/05 - Jay Vosburgh <fubar@us.ibm.com>
- * - Support for generating gratuitous ARPs in active-backup mode.

- * as needed. Set version to 2.6.2.
- * 2005/06/08 - Jason Gabler <jygabler at lbl dot gov>
- * - alternate hashing policy support for mode 2

+ * is not an exhaustive list.)
+ * - The RBUF uses 64-byte mpackets.
+ * - RX descriptors reside in SRAM, and have the following format:
+ * struct rx_desc
+ * {
+ * // to uengine
+ * u32 buf_phys_addr;
+ * u32 buf_length;
+ *
+ * // from uengine
+ * u32 channel;
+ * u32 pkt_length;
+ * };
+ * - Packet data resides in DRAM.
+ * - Packet buffer addresses are 8-byte aligned.
+ * - Scratch ring 0 is rx_pending.
+ * - Scratch ring 1 is rx_done, and has status condition 'full'.
+ * - The host triggers rx_done flush and rx_pending refill on seeing INTA.
+ * - This code is run on all eight threads of the microengine it runs on.
+ *
+ * Local memory is used for per-channel RX state.

+ * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
+ * is not an exhaustive list.)
+ * - The TBUF uses 64-byte mpackets.
+ * - TX descriptors reside in SRAM, and have the following format:
+ * struct tx_desc
+ * {
+ * // to uengine
+ * u32 buf_phys_addr;
+ * u32 pkt_length;
+ * u32 channel;
+ * };
+ * - Packet data resides in DRAM.
+ * - Packet buffer addresses are 8-byte aligned.
+ * - Scratch ring 2 is tx_pending.
+ * - Scratch ring 3 is tx_done, and has status condition 'full'.
+ * - This code is run on all eight threads of the microengine it runs on.
