From dce53396b52db1646f93b3ff3a14f4a5a8cf9211 Mon Sep 17 00:00:00 2001 From: Vasundhara Volam Date: Fri, 5 Oct 2018 00:26:01 -0400 Subject: [PATCH] bnxt_en: Fix enables field in HWRM_QUEUE_COS2BW_CFG request [ Upstream commit 5db0e0969af6501ad45fe0494039d3b9c797822b ] In HWRM_QUEUE_COS2BW_CFG request, enables field should have the bits set only for the queue ids which are having the valid parameters. This causes firmware to return error when the TC to hardware CoS queue mapping is not 1:1 during DCBNL ETS setup. Fixes: 2e8ef77ee0ff ("bnxt_en: Add TC to hardware QoS queue mapping logic.")
