[dpdk-dev] [PATCH 2/2] net/bnxt: fix an issue with rxq0 stop

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

For the stingray platform and other platforms needing tighter
control of resource utilization, we process async events on
receive completion ring0.

For other chips there is a dedicated completion ring for
asynchronous event handling instead of handling these events
on a receive completion ring.

This patch fixes the check for rxq0 stop.

Fixes: 05b5e4821c1e ("net/bnxt: use dedicated CPR for async events")
