From: Li Zhijian
Date: Wed Nov 17 2021 - 00:49:08 EST


Install netdevsim to provide /sys/bus/netdevsim/new_device interface.

It helps to fix:
# ok 97 9a7d - Change ETS strict band without quantum # skipped - skipped - previous setup failed 11 ce7d
#
#
# -----> prepare stage *** Could not execute: "echo "1 1 4" > /sys/bus/netdevsim/new_device"
#
# -----> prepare stage *** Error message: "/bin/sh: 1: cannot create /sys/bus/netdevsim/new_device: Directory nonexistent
# "
#
# -----> prepare stage *** Aborting test run.
#
#
# <_io.BufferedReader name=5> *** stdout ***
