Hi,

FYI, your patch has been queued to stable release 18.02.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/02/18. So please
shout if anyone has objections.

Subject: [PATCH] net/vdev_netvsc: remove specified devices IP check

[ upstream commit 0b39cc820ae57319d9d9a3609843c94d0b9a4bbb ]

If the netvsc driver starts in blacklist mode, it does not
automatically probe IP associated netvsc devices. Therefore, the only
way to probe them is to specify them by the EAL command line, using the
"force" parameter to skip the IP check in the driver.

>From now on, the user does not need to add the "force" parameter if he
specifies an IP associated netvsc device by the EAL command line, and the
responsibility of the IP check is now in the user's hands.

However, in the absence of any specification, the driver still skips IP
associated netvsc devices.
