[dpdk-dev] [PATCH v2 3/5] net/bnxt: fix vnic allocation failure on port toggle

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

From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>

bnxt_init_chip called on port start keeps incrementing rx_cosq_cnt.
Hence more vnics are allocated with less number of rings on each port
stop/start operation. Eventually vnic allocation fails due to incorrect
ring group as no ring gets allocated to the vnic.

Fixes: 84d49664b5b2 ("net/bnxt: support CoS classification")
