I think you (and Jakub) did. :-) Looks like a "queue" is a good
(necessary) abstraction, but I need to think more about how to e.g.
access "dedicated/isolated" AF_XDP queues or XDP Tx queues in a
convenient way.

I'll still aiming for making it dead-easy (like Jonathan describes) to
use AF_XDP sockets...

Thanks a lot for all the input/help!
