Subject: net/netvsc: initialize link state
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=047ad3787a2f5d99277e0d8d756580a1d5ea2891;p=dpdk.git

net/netvsc: initialize link state

If application is using link state interrupt, the correct link state
needs to be filled in when device is started. This is similar to
how virtio updates link information.

Fixes: 4e9c73e96e83 ("net/netvsc: add Hyper-V network device")
