[RFC PATCH v2 8/9] net: dsa: dsa_slave_phy_connect(): extend phy's flags with port specific phy flags

From: Oleksij Rempel
Date: Mon May 10 2021 - 08:50:01 EST


This patch extends the flags of the phy that's being connected with the
port specific flags of the switch port.

This is needed to handle a port specific erratum of the KSZ8873 switch,
which is added in a later patch.
