Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Pull networking fixes from David Miller:
 "Several bug fixes, some to new features appearing in this merge
  window, some that have been around for a while.

  I have a short list of known problems that need to be sorted out, but
  all of them can be solved easily during the run up to 3.6-final.

  I'll be offline until Sunday afternoon, but nothing need hold up
  3.6-rc1 and the close of the merge window, networking wise, at this
  point.

  1) Fix interface check in ipv4 TCP early demux, from Eric Dumazet.

  2) Fix a long standing bug in TCP DMA to userspace offload that can
     hang applications using MSG_TRUNC, from Jiri Kosina.

  3) Don't allow TCP_USER_TIMEOUT to be negative, from Hangbin Liu.

  4) Don't use GFP_KERNEL under spinlock in kaweth driver, from Dan
     Carpenter"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  tcp: perform DMA to userspace only if there is a task waiting for it
  Revert "openvswitch: potential NULL deref in sample()"
  ipv4: fix TCP early demux
  net: fix rtnetlink IFF_PROMISC and IFF_ALLMULTI handling
  USB: kaweth.c: use GFP_ATOMIC under spin_lock
  tcp: Add TCP_USER_TIMEOUT negative value check
  bcma: add missing iounmap on error path
  bcma: fix regression in interrupt assignment on mips
  mac80211_hwsim: fix possible race condition in usage of info->control.sta & control.vif
