Subject: [PATCH net-next v5 08/13] netlink: specs: add ethnl PHY_GET command set
Date: Thu, 21 Dec 2023 19:00:41 +0100
Message-ID: <20231221180047.1924733-9-maxime.chevallier@bootlin.com>

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.
