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.

V1: https://lore.kernel.org/netdev/20250702082806.706973-1-maxime.chevallier@bootlin.com/

  net: netdevsim: Add PHY support in netdevsim
  selftests: ethtool: Drop the unused old_netdevs variable
  selftests: ethtool: Introduce ethernet PHY selftests on netdevsim

Appears to break the build for BPF CI:
