Subject: [dpdk-dev] [PATCH v2 03/17] net/bnxt: fix rxq stop/start handling
Date: Tue, 1 Oct 2019 22:54:09 -0700 [thread overview]
Message-ID: <20191002055423.99659-4-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20191002055423.99659-1-ajit.khaparde@broadcom.com>
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
Driver should not change "deferred_start" state of the rx queues.
It should get the state in queue_setup_op() and use that value.
Since the deferred start state was being used in the packet receive
functions to determine whether a stopped rx ring should be polled,
introduced a per-rxq flag to track queue stopped/started state.
Fixes: 9b63c6fd70e3 ("net/bnxt: support Rx/Tx queue start/stop")
