From eb8336dbe373edd1ad6061c543e4ba6ea60f6cc9 Mon Sep 17 00:00:00 2001 From: Mark Zhang Date: Thu, 8 Sep 2022 13:09:03 +0300 Subject: RDMA/cm: Use DLID from inbound/outbound PathRecords as the datapath DLID In inter-subnet cases, when inbound/outbound PRs are available, outbound_PR.dlid is used as the requestor's datapath DLID and inbound_PR.dlid is used as the responder's DLID. The inbound_PR.dlid is passed to responder side with the "ConnectReq.Primary_Local_Port_LID" field. With this solution the PERMISSIVE_LID is no longer used in Primary Local LID field.
