2009-05-19ixgbe: Cleanup feature setup code to make the code more readableJesse Brandeburg
This is purely a cleanup patch. This collapses some of the code required when we configure our Tx and Rx feature sets, and makes the code more readable and maintainable.

2009-05-19ixgbe: Change Direct Attach Twinax cable detection for SFP+ NICsPeter P Waskiewicz Jr
The SFF specification for Direct Attach cable detection has now been ratified. Previously, DA cable detect was looking at the Twinaxial bit in byte 9 of the SFP+ EEPROM. The spec now defines active and passive DA cables in byte 8 of the SFP+ EEPROM. This patch changes the cable detection for both 82598 and 82599 SFP+ adapters to conform to the new spec.

2009-05-19r8169: allow true forced mode settingfrançois romieu
Due to mostly historic reasons, including a lack of reliability of the link handling (especially with the older 8169), the current r8169 driver emulates forced mode setting by limiting the advertised modes. With this change the driver allows real 10/100 forced mode settings on the 8169 and 8101/8102. Original idea by Vincent Steenhoute. The RTL_GIGA_MAC_VER_03 tweak was extracted from Realtek's r8169 v6.010.00 driver.

2009-05-18net: release dst entry in dev_hard_start_xmit()Eric Dumazet
One point of contention in high network loads is the dst_release() performed when a transmited skb is freed. This is because NIC tx completion calls dev_kree_skb() long after original call to dev_queue_xmit(skb). CPU cache is cold and the atomic op in dst_release() stalls. On SMP, this is quite visible if one CPU is 100% handling softirqs for a network device, since dst_clone() is done by other cpus, involving cache line ping pongs. It seems right place to release dst is in dev_hard_start_xmit(), for most devices but ones that are virtual, and some exceptions. David Miller suggested to define a new device flag, set in alloc_netdev_mq() (so that most devices set it at init time), and carefuly unset in devices which dont want a NULL skb->dst in their ndo_start_xmit(). List of devices that must clear this flag is : - loopback device, because it calls netif_rx() and quoting Patrick : "ip_route_input() doesn't accept loopback addresses, so loopback packets already need to have a dst_entry attached." - appletalk/ipddp.c : needs skb->dst in its xmit function - And all devices that call again dev_queue_xmit() from their xmit function (as some classifiers need skb->dst) : bonding, vlan, macvlan, eql, ifb, hdlc_fr Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

Sysfs files for a network device can not unconditionally take the rtnl_lock as the bonding sysfs files do.

2009-05-17bonding: fix link down handling in 802.3ad modeStephen Hemminger
One of the purposes of bonding is to allow for redundant links, and failover correctly if the cable is pulled. If all the members of a bonded device have no carrier present, the bonded device itself needs to report no carrier present to user space so management tools (like routing daemons) can respond. Bonding in 802.3ad mode does not work correctly for this because it incorrectly chooses a link that is down as a possible aggregator.

82599 supports using either link flow control or priority flow control when in DCB mode. The dcbnl interface already supports sending down configurations through rtnetlink that can enable LFC when DCB is enabled, so the driver should take advantage of this. 82598 does not support using LFC when DCB is enabled, so explicitly disable it when we're in DCB mode.

2009-05-17fcoe: adds spma mode supportVasu Dev
If we can find a type NETDEV_HW_ADDR_T_SAN mac address from the corresponding netdev for a fcoe interface then sets up added the fc->ctlr.spma flag and stores spma mode address in ctl_src_addr. In case the spma flag is set then:- 1. Adds spma mode MAC address in ctl_src_addr as secondary MAC address, the FLOGI for FIP and pre-FIP will go out using this address. 2. Cleans up stored spma MAC address in ctl_src_addr in fcoe_netdev_cleanup. 3. Sets up spma bit in fip_flags for FIP solicitations along with exiting FPMA bit setting. 4. Initialize the FLOGI FIP MAC descriptor to stored spma MAC address in ctl_src_addr. This is used as proposed FCoE MAC address from initiator along with both SPMA and FPMA bit set in FIP solicitation, in response the switch may grant any FPMA or SPMA mode MAC address to initiator. Removes FIP descriptor type checking against ELS type ELS_FLOGI in fcoe_ctlr_encaps to update a FIP MAC descriptor, instead now checks against FIP_DT_FLOGI. I've tested this with available FPMA-only FCoE switch but since data_src_addr is updated using same old code for both FPMA and SPMA modes with FIP or pre-FIP links, so added SPMA mode will work with SPMA-only switch also provided that switch grants a valid MAC address.

2009-05-17fcoe: consolidates netdev related config and cleanup for spma modeVasu Dev
Currently fcoe_netdev_config adds netdev pkt handler for fcoe pkts, fcoe_if_create adds netdev pkt handler for fip packets, a secondary MAC address is added by fcoe_netdev_config and then later cleanup for these netdev related config/adds is done only during fcoe_if_destroy and no cleanup done on error during fcoe interface creation after above netdev config calling in fcoe_if_create. So this patch adds single func for above mentioned cleanup the fcoe_netdev_cleanup and then calls this func on either fcoe interface destroy or exiting from fcoe_if_create due to an error after fcoe/fip related above netdev config is done. Moved netdev pkt handler addition code blocks for fip pkts close to similar code block for foce pkt in fcoe_netdev_config, so that added fcoe_netdev_cleanup could be called on error from fcoe_netdev_config to undo these both additions for fcoe/fip pkt handlers. This move required reference to fcoe_fip_recv in fcoe_netdev_config, so moved fip related functions fcoe_fip_recv, fcoe_fip_send and fcoe_update_src_mac above fcoe_netdev_config. This consolidation will enable spma mode support in next patch to easily add or delete spma mode mac address beside fixing current no cleanup issue during error.

2009-05-17ixgbe: Add SAN MAC address to the RAR, return the address to DCBWaskiewicz Jr, Peter P
After acquiring the SAN MAC address from the EEPROM, we need to program it into one of the RARs. Also, DCB will use this MAC address to run DCBX commands, so it doesn't have to play musical MAC addresses when things like bonding enter the picture. So we need to return the MAC address through the netlink interface to userspace. This also moves the init_rx_addrs() call out of start_hw() and into reset_hw(). We shouldn't try to read any of the RAR information before initializing our internal accounting of the RAR table, which was what was happening.

This patch implements the Storage Address entrypoint from the net device. It will read the SAN MAC addresses from the EEPROM of the 82599 hardware, and make them available to the FCoE stack through the net device. Also, add/del the SAN MAC address to the netdev dev_addr_list via the kernel api dev_addr_add()/dev_addr_del() when there is a valid SAN MAC supported by the HW.
