[PATCH net-next v5 7/8] net: dsa: dsa_slave_phy_connect(): extend phy's flags with port specific phy flags

From: Oleksij Rempel
Date: Mon Jun 14 2021 - 00:32:05 EST


The current get_phy_flags() is only processed when we connect to a PHY
via a designed phy-handle property via phylink_of_phy_connect(), but if
we fallback on the internal MDIO bus created by a switch and take the
dsa_slave_phy_connect() path then we would not be processing that flag
and using it at PHY connection time.
