Recently we added multi-queue support to netdevsim in commit d4861fc6be58
("netdevsim: Add multi-queue support"); add a few control-plane selftests
for sch_mq using this new feature.
Use nsPlugin.py to avoid network interface name collisions.

Hi all,
Here are some control-plane selftests for the mq Qdisc using netdevsim's
new multi-queue feature. We are planning to add more data-plane selftests
in the future.
Thank you,
Peilin Ye

Like I mentioned to Peilin, I am _not_ sure whether it is better to create
netdevsim device in such a way. Maybe we need to create it before
these tests and pass it via cmdline?? Lucas?
Thanks.
