Subject: [dpdk-dev] [PATCH v2 10/12] net/bnxt: fix to handle interface change status in port start only
Date: Wed, 9 Oct 2019 18:41:51 -0700
Message-ID: <20191010014153.64908-11-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20191010014153.64908-1-ajit.khaparde@broadcom.com>
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
Driver issues hwrm_if_change when the port is started and stopped.
This command returns whether the fw has undergone a reset while port
was down. Fix to handle hwrm_if_change status during port start only.
Fixes: 92d6617b6e33 ("net/bnxt: inform firmware about IF state changes")
