o ioctls: SIOCGIFADDR, SIOCSIFADDR, SIOCGSTAMP, SIOCGSTAMPNS

o Get source/destination lladdr from UDP packet

No examples for:
o AF_IEEE802154 (SOCK_RAW)
o AF_INET6 (SOCK_STREAM)

TODO:
o SOCK_RDM (Provides a reliable datagram layer that does not guarantee ordering)
can we consider this with frame retries enabled???
o Remove AF_IEEE802154 SOCK_RAW?? Does AF_PACKET cover all our needs here??
