Subject: [PATCH net-next v2 0/3] netdevsim: add support for PHY devices

Hi everyone,

Here's a V2 for the netdevsim PHY support, including a bugfix for
NETDEVSIM=m as well as a round of shellcheck cleanups for
ethtool-phy.sh.

The idea of this series is to allow attaching virtual PHY devices to
netdevsim, so that we can test PHY-related ethtool commands. This can be
extended in the future for phylib testing as well.
