[NET]: Make AF_PACKET handle multiple network namespaces
This is done by making packet_sklist_lock and packet_sklist per network namespace and adding an additional filter condition on received packets to ensure they came from the proper network namespace. Changes from v1: - prohibit to call inet_dgram_ops.ioctl in other than init_net Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: Eric W.
