Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/phy/amd-xgbe-phy.c drivers/net/wireless/iwlwifi/Kconfig include/net/mac80211.h iwlwifi/Kconfig and mac80211.h were both trivial overlapping changes. The drivers/net/phy/amd-xgbe-phy.c file got removed in 'net-next' and the bug fix that happened on the 'net' side is already integrated into the rest of the amd-xgbe driver. Signed-off-by: David S. Miller <davem@davemloft.net>
