[dpdk-dev] [PATCH v2 10/12] net/bnxt: fix to handle interface change status in port start only

[Ajit Khaparde]

From: Kalesh AP <kalesh-anakkur.purayil at 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")
