Then that's increasing the udp_sock structure size for a narrow use
case which will get push back. I think it's going to be better to
stick with one sock pointer. We could maybe redefine sk_user_data as a
pointer to an allocated structure or array so it can hold multiple
user_data pointers (in lieu of chaining).

We do not have a lot of UDP sockets per host, I do not believe it
should be a problem adding stuff in them.

Eric,

Is QUIC using unconnected sockets then?
