Yes, sorry I didn't point to that as well. Just to be clear: I have no
clue how this thing is actually wired up, or if you could use three
interrupts on the MT7621 too. I just messed with it until I got
something to work, based on Renés original idea and code.
My idea is a just a copy of mtk_handle_irq_{rx,tx} see [1]
You probably want to look at the staging driver or Ubiquity source
with a 3.10.x kernel [2] or padavan with 3.4.x kernel [3].
AFAIK mt7621 only has 1 IRQ for ethernet part.
correct there is only 1 single IRQ on mt7621
