Subject: net/hinic/base: fix port start during FW hot update
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0194313b2df66d9308c79f501d1018a99b32098b;p=dpdk.git

net/hinic/base: fix port start during FW hot update

When repeatedly hotupdate firmware and start/stop port at the same time,
port start may be failed when cmdq reinit failed at the FW active phase,
so if cmdq fails, then reinit the cmdq when port start.

Fixes: d9ce1917941c ("net/hinic/base: add hardware operation")
