Subject: [PATCH net-next] tc-testing: Add control-plane selftests for sch_mq
From: Peilin Ye <peilin.ye@...edance.com>
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
