This patch reuses the framework already in place for sk_lookup, allowing it now to send a reply from the server fd directly, instead of having to create a socket bound to the original destination address and reply from there. It does this by passing the source address and port from where to reply from in a IP_ORIGDSTADDR ancillary message passed in sendmsg.
