Subject: [dpdk-dev] [PATCH v2 09/12] net/bnxt: enable interrupts after checking interface status from FW
Date: Wed,  9 Oct 2019 18:41:50 -0700
Message-ID: <20191010014153.64908-10-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. This command
returns whether the fw has undergone a reset while port was down and
driver does re-init of resources if fw has undergone a reset.
Fix to enable interrupts only after this check.

Fixes: 7c9b9cebadfc ("net/bnxt: fix async link handling and update")
