Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
net/batman-adv/bridge_loop_avoidance.c
net/batman-adv/bridge_loop_avoidance.h
net/batman-adv/soft-interface.c
net/mac80211/mlme.c
With merge help from Antonio Quartulli (batman-adv) and
Stephen Rothwell (drivers/net/usb/qmi_wwan.c).
The net/mac80211/mlme.c conflict seemed easy enough, accounting for a
conversion to some new tracing macros.
