[PATCH net-next 0/8] net: Allow targeting specific PHYs through netlink

[Maxime Chevallier]

Hi everyone,

This series is a resend of the las 8 patches of the link_topology series:
https://lore.kernel.org/netdev/20240404093004.2552221-1-maxime.chevallier@bootlin.com/

There were a some conflicts on the netlink specs, which I guess made the
series fail to apply.

All patches of this series allow accessing and using the PHYs from the
topology through netlink commands such as PLCA, PSE-PD, Cable testing
and strsets, and introduces a dedicated command to list said PHYs.

This re-send is simply rebased on net-next, with the addition of
Andrew's Reviewed-by tags.

Thanks,

Maxime
