* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:
  at91_can: Forgotten git 'add' of at91_can.c
  TI Davinci EMAC: Fix in vector definition for EMAC_VERSION_2
  ax25: Fix ax25_cb refcounting in ax25_ctl_ioctl
  virtio_net: Check for room in the vq before adding buffer
  virtio_net: avoid (most) NETDEV_TX_BUSY by stopping queue early.
  virtio_net: formalize skb_vnet_hdr
  virtio_net: don't free buffers in xmit ring
  virtio_net: return NETDEV_TX_BUSY instead of queueing an extra skb.
  virtio_net: skb_orphan() and nf_reset() in xmit path.
