net: dsa: bcm_sf2: Qualify phydev->dev_flags based on port
Similar to commit 92696286f3bb37ba50e4bd8d1beb24afb759a799 ("net: bcmgenet: Set phydev->dev_flags only for internal PHYs") we need to qualify the phydev->dev_flags based on whether the port is connected to an internal or external PHY otherwise we risk having a flags collision with a completely different interpretation depending on the driver. Fixes: aa9aef77c761 ("net: dsa: bcm_sf2: communicate integrated PHY revision to PHY driver") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
