Subject: [dpdk-dev] [PATCH v2 3/5] net/bnxt: fix vnic allocation failure on port toggle
Date: Mon,  4 Nov 2019 15:32:38 +0530	[thread overview]
Message-ID: <20191104100240.28974-4-kalesh-anakkur.purayil@broadcom.com> (raw)
In-Reply-To: <20191104100240.28974-1-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")
