[dpdk-dev] [PATCH v2 5/5] net/bnxt: fix incorrect COS queue mapping

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Ajit Khaparde <ajit.khaparde@broadcom.com>

While issuing hwrm_queue_qportcfg command, we are setting the
drv_qmap_cap bit which is causing the firmware to return incorrect COS
queue mapping. This bit is not required when COS classification is enabled.

Fixes: 698aa7e95325 ("net/bnxt: add code to determine the Tx COS queue")
