Can you perhaps send me an updated wording for this commit message as the title
and commit message conflict. The title says to use completion messages not
descriptors, while the body talks about moving away from a completion message
way of working.
Is the former method a descriptor writeback method, while the latter a head
pointer writeback? If so, I think the title could be:

"enic: use Tx head pointer not descriptor writeback"

or something similar.

Again, if you send on the updated commit text, I'll just update it on apply. I'd
ideally like to get this patchset pushed to next-net first thing Monday.
