[PATCH RFC net-next v8 12/13] net: ethtool: tsinfo: Add support for hwtstamp provider and get/set hwtstamp config

[Kory Maincent <kory.maincent@bootlin.com>]

Enhance 'get' command to retrieve tsinfo of hwtstamp providers within a
network topology and read current hwtstamp configuration.

Introduce support for ETHTOOL_MSG_TSINFO_SET ethtool netlink socket to
configure hwtstamp of a PHC provider. Note that simultaneous hwtstamp
isn't supported; configuring a new one disables the previous setting.

Also, add support for a specific dump command to retrieve all hwtstamp
providers within the network topology, with added functionality for
filtered dump to target a single interface.

Signed-off-by: Kory Maincent <kory.maincent@bootlin.com>

Pointer attached_dev is used to know if the phy is on the net topology.
This might not be enough and might need Maxime Chevallier link topology
