SubjectRe: [PATCH v3 07/28] IB/Verbs: Reform IB-ulp ipoib

I looked at it a bit, and I think Sean has also basically said, CM
does not support certain mixed port combinations. iWarp and IB simply
cannot be mixed with the current CM and it doesn't look easy to fix
that. We can fix a few point areas simply, but not all of it.

So we have to have the _dev tests, only to fill the CM's need and they
must have the all true/all false/BUG semantics CM demands.

Verify on register.

Really? Do you see any bugs/missed things? Both were made port
orthogonal when RoCEE was added, because RoCEE needs that.

CM wasn't because RoCEE and IB seem to use almost the same code,
though I wonder if mixing really works 100%..
