Are there any mandatory callbacks that EFA refuses other than this one
(which Gal said that it will support)?
All the EOPNOTSUPP ones. It *really* doesn't support kverbs at
all.
Oh wow, didn't realize that :)
Which is why my first thought was to just not present it via the
in-kernel client API at all.
Definitely, it should not appear to the client API at all..
This patch is needed most definitely.
I'm sure that all of those (other than modify_qp) are trivial
to add but it doesn't really make sense to have them if userspace
is not using uverbs for them.
Only req_notify really extends into userspace verbs though.
Is it? ibv_notify_cq doesn't go to the kernel afair..
