TRIGGER_NETDEV_TX + TRIGGER_NETDEV_RX = TRIGGER_NETDEV_ACTIVITY:

When calling into the driver, it probably makes the drivers simpler if
you do this simplification. Within the trigger code, keep them
separate, because that is what the user has configured.

I know such a simplification will make the marvell PHY driver simpler.
