Merge branch 'net-ipa-more-multi-channel-event-ring-work'

Alex Elder says:

====================
net: ipa: more multi-channel event ring work

This series makes a little more progress toward supporting multiple
channels with a single event ring.  The first removes the assumption
that consecutive events are associated with the same RX channel.

The second derives the channel associated with an event from the
event itself, and the next does a small cleanup enabled by that.

The fourth causes updates to occur for every event processed (rather
once).  And the final patch does a little more rework to make TX
completion have more in common with RX completion.
