Subject: [PATCH RFC net-next 09/12] net: dsa: ocelot: convert to
phylink_generic_validate()
Populate the supported interfaces and MAC capabilities for the Ocelot
DSA switches and remove the old validate implementation to allow DSA to
use phylink_generic_validate() for this switch driver.
The felix_vsc9959 and seville_vsc9953 sub-drivers only supports a
single interface mode, defined by ocelot_port->phy_mode, so we indicate
only this interface mode to phylink. Since phylink restricts the
ethtool link modes based on interface, we do not need to make the MAC
capabilities dependent on the interface mode.
