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. Signed-off-by: David S. Miller <davem@davemloft.net>
