Subject: net/netvsc: support per-queue info requests
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c7b82b14e30027e5309c41fecea8d1ecb5843d02;p=dpdk.git

net/netvsc: support per-queue info requests

There is not a lot of info here from this driver.
But worth supporting these additional info queries.
