Subject: [dpdk-dev] [PATCH] net/bnxt: fix to reset Rx next consumer index
Date: Tue, 10 Aug 2021 11:37:31 +0530	[thread overview]
Message-ID: <20210810060731.30127-1-somnath.kotur@broadcom.com> (raw)

In bnxt_init_one_rx_ring(), reset this variable internal to the driver
ring to 0, so that there is no mismatch with actual value in HW on
traffic resumption.

Fixes: 03c8f2fe111c ("net/bnxt: detect bad opaque in Rx completion")
Cc: stable@dpdk.org
