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

Conflicts:
	net/mac80211/sta_info.c
	net/wireless/core.h

Two minor conflicts in wireless.  Overlapping additions of extern
declarations in net/wireless/core.h and a bug fix overlapping with
the addition of a boolean parameter to __ieee80211_key_free().
