1. Channels vs queues vs global.

Jakub: no per-channel.
David (Ahern): it's worth it to separate as Rx/Tx.
Toke is fine with globals at the end I think?  

Well, I don't like throwing data away, so in that sense I do like
per-queue stats, but it's not a very strong preference (i.e., I can live
with either)...

We don't even have a clear definition of a queue in Linux.

As I said, adding this API today without a strong user and letting
drivers diverge in behavior would be a mistake.
