[dpdk-dev] [PATCH 2/7] net/bnxt: fix default timeout for ver_get command

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Rahul Gupta <rahul.gupta@broadcom.com>

Initially when driver is loading, there is no HWRM timeout configured
by FW, the VER_GET command needs use default timeout as 500ms and
while recovering from fatal/non-fatal FW error, it should use timeout
as 50ms.

Fixes: 458f0360e8dc ("net/bnxt: get default HWRM command timeout from FW")
