Completion channels are created with ia_open for CNO events and

no EVD(cq) and IB doesn't. These completion channels need to be
destroyed at close along with a CQ for the "EP without EVD" case.

The libiscsi passthrough mode invokes the transport xmit calls directly

Two minor flows in iser's data path still use allocations,

Currently, the recv buffer posting logic is based on the transactional
nature of iser which allows for posting a buffer before sending a PDU.
Change this to post only when the number of outstanding recv buffers is
below a water mark and in a batched manner, thus simplifying and
optimizing the data
towards a major change in the recv buffer posting logic, with which
the problem commit bba7ebb "avoid recv buffer exhaustion caused by
unexpected PDUs" comes to solve doesn't exist any more, revert it.

Proposed new algorithm for calculation of root switch for multicast

and switches - multicast members themselves are involved in root
