Unlike with TCP sockets, UDP sockets may receive packets from multiple

on different cores through RSS or other Flow-Steering HW mechanisms
which could mean different napi contexts for the same socket, is that
a problem here? what's the severity?
Nothing will break if you poll on the wrong queue.
Your data will come through normal NAPI processing of the right queue.
Can you elaborate a little further, why you call this "wrong" and "right"?
