- The :c:func:`validate` method should mask the supplied supported mask,
- and ``state->advertising`` with the supported ethtool link modes.
- These are the new ethtool link modes, so bitmask operations must be
- used. For an example, see ``drivers/net/ethernet/marvell/mvneta.c``.
+ The :c:func:`mac_get_caps` method is optional, and if provided should

+ Phylink will use these capabilities in combination with permissible

The :c:func:`mac_link_state` method is used to read the link state
from the MAC, and report back the settings that the MAC is currently
