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: (55 commits) netxen: fix tx ring accounting netxen: fix detection of cut-thru firmware mode forcedeth: fix dma api mismatches atm: sk_wmem_alloc initial value is one net: correct off-by-one write allocations reports via-velocity : fix no link detection on boot Net / e100: Fix suspend of devices that cannot be power managed TI DaVinci EMAC : Fix rmmod error net: group address list and its count ipv4: Fix fib_trie rebalancing, part 2 pkt_sched: Update drops stats in act_police sky2: version 1.23 sky2: add GRO support sky2: skb recycling sky2: reduce default transmit ring sky2: receive counter update sky2: fix shutdown synchronization sky2: PCI irq issues sky2: more receive shutdown sky2: turn off pause during shutdown ... Manually fix trivial conflict in net/core/skbuff.c due to kmemcheck
