Subject: bnxt_en: Fix enables field in HWRM_QUEUE_COS2BW_CFG request
Patch-mainline: v4.19-rc7
Git-commit: 5db0e0969af6501ad45fe0494039d3b9c797822b
References: bsc#1104745 FATE#325918
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.")
