[dpdk-dev] [PATCH v2] net/fm10k: initialize link status in device start

[Xiao Wang]

Fm10k host driver can't manage PHY directly and provides a fake link
status by always reporting LINK_UP. We should initialize link status
in device start, otherwise application will get LINK_DOWN status
when LSC configured.

Fixes: 9ae6068c86da ("fm10k: add dev start/stop")
