Subject: [PATCH rdma-rc] RDMA/bnxt_re: Avoid clearing VLAN_ID mask in modify qp path
Date: Mon, 10 Mar 2025 22:16:36 -0700	[thread overview]
Message-ID: <1741670196-2919-1-git-send-email-selvin.xavier@broadcom.com> (raw)

From: Saravanan Vajravel <saravanan.vajravel@broadcom.com>

Driver is always clearing the mask that sets the VLAN ID/Service Level
in the adapter. Recent change for supporting multiple traffic class
exposed this issue.

Allow setting SL and VLAN_ID while QP is moved from INIT to RTR state.

Fixes: 1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
Fixes: c64b16a37b6d ("RDMA/bnxt_re: Support different traffic class")
