af_packet: Teach to listen for multiple unicast addresses.
The the PACKET_ADD_MEMBERSHIP and the PACKET_DROP_MEMBERSHIP setsockopt calls for af_packet already has all of the infrastructure needed to subscribe to multiple mac addresses. All that is missing is a flag to say that the address we want to listen on is a unicast address. So introduce PACKET_MR_UNICAST and wire it up to dev_unicast_add and dev_unicast_delete. Additionally I noticed that errors from dev_mc_add were not propagated from packet_dev_mc so fix that. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S.
