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. The patches are organized as follows: * Patch 1 converts an OPA path record to an IB path record before placing GIDs from the path record onto a CM reqeust message. If the OPA path records were to contain exteded LIDs, the converted IB path record would contain OPA GIDs in the SGID and DGID fields. * 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 * Patch 4 changes the sgid parameter back to an IB GID when handing a request thereby ensuring that underlying handers of the CM request message such as IPoIB continue to work when it compares an incoming GID with the GID assign to its interface.
