In this patch, I implement UDP_REPAIR sockoption and a new path in
udp_recvmsg for dumping the corked packet in UDP socket's send queue.

A userspace program can use recvmsg syscall to get the packet's data and
the msg_name information of the packet. Currently, other related
information in inet_cork that are set in cmsg are not dumped.

[ intended to include in my previous response ]

What other related information? Fields like transmit_time and gso_size?

This would be another reason to prefer dropping the packet over trying
to restore it incompletely.
