ethtool: Introduce a command to list PHYs
It is now possible to list all Ethernet PHYs that are present behind a
given interface, since the following linux commit :
63d5eaf35ac3 ("net: ethtool: Introduce a command to list PHYs on an interface")
This command relies on the netlink DUMP command to list them, by allowing to
pass an interface name/id as a parameter in the DUMP request to only
list PHYs on one interface.
Therefore, we introduce a new helper function to prepare a interface-filtered
dump request (the filter can be empty, to perform an unfiltered dump),
and then uses it to implement PHY enumeration through the --show-phys
command.
