Lots of overlapping changes, mostly trivial in nature.

The mlxsw conflict was resolving using the example
resolution at:

* If only IP_QP_AV was set, add in IB_QP_PORT as well (the
* verbs layer driver does not track primary port changes

* AV is modified, the primary port should also be modified).
