Re: [PATCH v5 00/21] ibmvfc: initial MQ development/enablement

Tyrel,
Recent updates in pHyp Firmware and VIOS releases provide new
infrastructure towards enabling Subordinate Command Response Queues
(Sub-CRQs) such that each Sub-CRQ is a channel backed by an actual
hardware queue in the FC stack on the partner VIOS. Sub-CRQs are
registered with the firmware via hypercalls and then negotiated with
the VIOS via new Management Datagrams (MADs) for channel setup.

This initial implementation adds the necessary Sub-CRQ framework and
implements the new MADs for negotiating and assigning a set of
Sub-CRQs to associated VIOS HW backed channels.
Applied to 5.12/scsi-staging, thanks!
