[PATCH net-next v6 08/13] netlink: specs: add ethnl PHY_GET command set

Maxime Chevallier maxime.chevallier at bootlin.com
Fri Jan 26 10:38:45 PST 2024


The PHY_GET command, supporting both DUMP and GET operations, is used to
retrieve the list of PHYs connected to a netdevice, and get topology
information to know where exactly it sits on the physical link.

Add the netlink specs corresponding to that command.
