Can not control LAN/WAN leds with ath79 branch

With 19.07 ar71xx branches, LAN/WAN LEDs can be turned off, now with ath79 branches (rc1, rc2, snapshot, master snapshot), no more handle to turn off these LEDs


is NOT populated with LANs and WAN virtual links while ar71xx branches do.
This happens with WDR4900V2, TL-archer C7V2.

Any suggestions to turn these blinking LEDs off?

This extensions to the drivers isn't ported to the device tree based target and I think no one will make the needed effort to port this to ath79 in the near future.

The simplest solution is a black insulating tape.
