Jack,Roland I believe that adding entries to this enum means ABI change towards
libibverbs or eventually cause ABI change between libibverbs and its consumers,
(e.g change in size/content of the verbs context structure, etc), correct?
I'd like to use this ABI change and introduce/expose also the ib_modify_cq verb
to user space. Basically, the related patches should be quite simple (uverbs,
libibverbs, libmlx4), still, I'll be glad if you tell/coach me against what
code base to do that.
One more thing I'd like to add to libibverbs and some device driver libraries
is send-with-invalidate, but this is only user space patch set without any
kernel/user, lib/app ABI change, correct?
Or.
