Yes, that is the way it is intended to be used. The MAC driver can
pass flags to the PHY. It is a fragile API, since the MAC needs to
know what PHY is being used, since the flags are driver specific.

One option would be to modify the assignment in phy_attach_direct() to
OR in the flags passed to it with flags which are already in
phydev->dev_flags.
