How about, if either bit is set in drv->features, then assume the phy
driver really knows what it's doing, and just copy those bits to
phydev->supported?

if (drv->features & (SUPPORTED_Pause | SUPPORTED_AsymPause)) {
    phydev->supported &= ~(SUPPORTED_Pause | SUPPORTED_AsymPause);
    phydev->supported |= drv->features & (SUPPORTED_Pause |
SUPPORTED_AsymPause);
} else
    phydev->supported |= SUPPORTED_Pause | SUPPORTED_AsymPause;
