Subject: [dpdk-dev] [RFT] net/netvsc: initialize link state
Date: Thu, 6 Feb 2020 16:10:38 -0800 [thread overview]
Message-ID: <20200207001038.7254-1-sthemmin@microsoft.com> (raw)
In-Reply-To: <20200206105541.1186-1-mgamal@redhat.com>
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.
Reported-by: Mohammed Gamal <mgamal@redhat.com>

This version marked RFT because am in airport without access to a
machine to test it.
