[PATCH rdma-next v3 0/3] Enhance IB CM to support OPA extended LIDs

[Don Hiatt <don.hiatt-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

This patch series adds enhancements to support extended LIDs in the
IB CM protocol. The core idea is to trasmit extended LIDs as OPA GIDs
on the wire in the primary_local_gid, primary_remote_gid,
alternate_local_gid and alternate_remote_gid fields of a CM request.
On the receiving side, the extended LID is retrieved from these
gids when processing the connection request.

Changes from v2:
---------------
* Replace repeated record type logic with cm_path_set_rec_type().

Changes from v1:
---------------
* Replace 'IB/CM: Convert OPA Path record to IB during CM request'
  with Patch 1 to add OPA path record support to CM.
* Remove 'IB/CM: Change sgid to IB GID when handling CM request'
  as it is no longer need with the introduction of Patch 1.

The patches are organized as follows:

* Patch 1 adds OPA path record support to the Connection Manager.
* Patch 2 creates OPA path records when handling a connection request
  if the request contained OPA GIDs.
* Patch 3 'extracts' the OPA extended LIDs from the GID fields when
  handling the connection request

Please note that these patches apply on top of the previously submmitted
patch set with subject: "[PATCH rdma-next 0/8] Add OPA extended LID support"
