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

Conflicts:
	include/linux/netdevice.h
	net/core/sock.c

Trivial merge issues.

Removal of "extern" for functions declaration in netdevice.h
at the same time "const" was added to an argument.

Two parallel line additions in net/core/sock.c
