Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6: (1750 commits) ixgbe: Allow Priority Flow Control settings to survive a device reset net: core: remove unneeded include in net/core/utils.c. e1000e: update version number e1000e: fix close interrupt race e1000e: fix loss of multicast packets e1000e: commonize tx cleanup routine to match e1000 & igb netfilter: fix nf_logger name in ebt_ulog. netfilter: fix warning in ebt_ulog init function. netfilter: fix warning about invalid const usage e1000: fix close race with interrupt e1000: cleanup clean_tx_irq routine so that it completely cleans ring e1000: fix tx hang detect logic and address dma mapping issues bridge: bad error handling when adding invalid ether address bonding: select current active slave when enslaving device for mode tlb and alb gianfar: reallocate skb when headroom is not enough for fcb Bump release date to 25Mar2009 and version to 0.22 r6040: Fix second PHY address qeth: fix wait_event_timeout handling qeth: check for completion of a running recovery qeth: unregister MAC addresses during recovery. ... Manually fixed up conflicts in: drivers/infiniband/hw/cxgb3/cxio_hal.h drivers/infiniband/hw/nes/nes_nic.c
