2007-10-15Use dcr_host_t.base in dcr_unmap()Michael Ellerman
With the base stored in dcr_host_t, there's no need for callers to pass the dcr_n into dcr_unmap(). In fact this removes the possibility of them passing the incorrect value, which would then be iounmap()'ed.

2007-10-15Add dcr_host_t.base in dcr_read()/dcr_write()Michael Ellerman
Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we can save them the trouble and do it in dcr_read()/dcr_write(). As some background to why we just went through all this jiggery-pokery, benh sayeth: Initially the goal of the dcr_read/dcr_write routines was to operate like mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx hardware, indirect DCR access is a pain (goes through a table of instructions) and it's useful to have the compiler resolve an absolute DCR inline. We decided that wasn't worth the API bastardisation since most places where absolute DCR values are used are low level 4xx-only code which may as well continue using mfdcr/mtdcr, while the new API is designed for device "instances" that can exist on 4xx and Axon type platforms and may be located at variable DCR offsets.

2007-10-15Use dcr_host_t.base in ibm_emac_malMichael Ellerman

2007-10-15net/bonding: Optionally allow ethernet slaves to keep own MACJay Vosburgh
Update the "don't change MAC of slaves" functionality added in previous changes to be a generic option, rather than something tied to IB devices, as it's occasionally useful for regular ethernet devices as well. Adds "fail_over_mac" option (which is automatically enabled for IB slaves), applicable only to active-backup mode. Includes documentation update. Updates bonding driver version to 3.2.0.

2007-10-15net/bonding: Destroy bonding master when last slave is goneMoni Shoua
When bonding enslaves non Ethernet devices it takes pointers to functions in the module that owns the slaves. In this case it becomes unsafe to keep the bonding master registered after last slave was unenslaved because we don't know if the pointers are still valid. Destroying the bond when slave_cnt is zero ensures that these functions be used anymore.

2007-10-15net/bonding: Enable IP multicast for bonding IPoIB devicesMoni Shoua
Allow to enslave devices when the bonding device is not up. Over the discussion held at the previous post this seemed to be the most clean way to go, where it is not expected to cause instabilities. Normally, the bonding driver is UP before any enslavement takes place. Once a netdevice is UP, the network stack acts to have it join some multicast groups (eg the all-hosts 224.0.0.1). Now, since ether_setup() have set the bonding device type to be ARPHRD_ETHER and address len to be ETHER_ALEN, the net core code computes a wrong multicast link address. This is b/c ip_eth_mc_map() is called where for multicast joins taking place after the enslavement another ip_xxx_mc_map() is called (eg ip_ib_mc_map() when the bond type is ARPHRD_INFINIBAND) Signed-off-by: Moni Shoua <monis at voltaire.com> Signed-off-by: Or Gerlitz <ogerlitz at voltaire.com> Acked-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-10-15net/bonding: Enable bonding to enslave netdevices not supporting ↵Moni Shoua
set_mac_address() This patch allows for enslaving netdevices which do not support the set_mac_address() function. In that case the bond mac address is the one of the active slave, where remote peers are notified on the mac address (neighbour) change by Gratuitous ARP sent by bonding when fail-over occurs (this is already done by the bonding code).

2007-10-15net/bonding: Enable bonding to enslave non ARPHRD_ETHERMoni Shoua
This patch changes some of the bond netdevice attributes and functions to be that of the active slave for the case of the enslaved device not being of ARPHRD_ETHER type. Basically it overrides those setting done by ether_setup(), which are netdevice **type** dependent and hence might be not appropriate for devices of other types. It also enforces mutual exclusion on bonding slaves from dissimilar ether types, as was concluded over the v1 discussion. IPoIB (see Documentation/infiniband/ipoib.txt) MAC address is made of a 3 bytes IB QP (Queue Pair) number and 16 bytes IB port GID (Global ID) of the port this IPoIB device is bounded to. The QP is a resource created by the IB HW and the GID is an identifier burned into the HCA (i have omitted here some details which are not important for the bonding RFC).

Commit 3d73c288 ("mlx4_core: Fix section mismatches") introduced a stupid bug in device init: when some of mlx4_init_one() was split off into __mlx4_init_one(), the call from the main mlx4_init_one() function was back to mlx4_init_one() rather than to __mlx4_init_one(), which leads to an obvious infinite loop if the function is every called.

Need to read and store sblk->status_idx before checking for more work. The status idx is later written back to the hardware when enabling interrupts to acknowledge how much work has been processed. If the order is reversed, we can end up acknowledging work we haven't processed. When completing bnx2_poll(), we should always break out of the while loop and return work_done instead of returning 0.
