Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/wireless/iwlwifi/pcie/trans.c include/linux/inetdevice.h The inetdevice.h conflict involves moving the IPV4_DEVCONF values into a UAPI header, overlapping additions of some new entries. The iwlwifi conflict is a context overlap. Signed-off-by: David S. Miller <davem@davemloft.net>
