* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (39 commits)
  [INET]: Small possible memory leak in FIB rules
  [NETNS]: init dev_base_lock only once
  [UNIX]: The unix_nr_socks limit can be exceeded
  [AF_UNIX]: Convert socks to unix_socks in scan_inflight, not in callbacks
  [AF_UNIX]: Make unix_tot_inflight counter non-atomic
  [AF_PACKET]: Allow multicast traffic to be caught by ORIGDEV when bonded
  ssb: Fix PCMCIA-host lowlevel bus access
  mac80211: fix MAC80211_RCSIMPLE Kconfig
  mac80211: make "decrypt failed" messages conditional upon MAC80211_DEBUG
  mac80211: use IW_AUTH_PRIVACY_INVOKED rather than IW_AUTH_KEY_MGMT
  mac80211: remove unused driver ops
  mac80211: remove ieee80211_common.h
  softmac: MAINTAINERS update
  rfkill: Fix sparse warning
  rfkill: Use mutex_lock() at register and add sanity check
  iwlwifi: select proper rate control algorithm
  mac80211: allow driver to ask for a rate control algorithm
  mac80211: don't allow registering the same rate control twice
  rfkill: Use subsys_initcall
  mac80211: make simple rate control algorithm built-in
