Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (66 commits) can-bcm: fix minor heap overflow gianfar: Do not call device_set_wakeup_enable() under a spinlock ipv6: Warn users if maximum number of routes is reached. docs: Add neigh/gc_thresh3 and route/max_size documentation. axnet_cs: fix resume problem for some Ax88790 chip ipv6: addrconf: don't remove address state on ifdown if the address is being kept tcp: Don't change unlocked socket state in tcp_v4_err(). x25: Prevent crashing when parsing bad X.25 facilities cxgb4vf: add call to Firmware to reset VF State. cxgb4vf: Fail open if link_start() fails. cxgb4vf: flesh out PCI Device ID Table ... cxgb4vf: fix some errors in Gather List to skb conversion cxgb4vf: fix bug in Generic Receive Offload cxgb4vf: don't implement trivial (and incorrect) ndo_select_queue() ixgbe: Look inside vlan when determining offload protocol. bnx2x: Look inside vlan when determining checksum proto. vlan: Add function to retrieve EtherType from vlan packets. virtio-net: init link state correctly ucc_geth: Fix deadlock ucc_geth: Do not bring the whole IF down when TX failure. ...
