Because? Hardware was updated? It was missing before?

You updated commit msg - looks fine - but same problem as before in your
code. Now MT7981 has 4-8 interrupts, even though you say here it has only
4.

Although I don't know how to treat this. Just say how many interrupts
are there (MT7981, MT7986, MT7988: 4 FE and 4 RSS), not 4 but later
actually 4+4.

I also do not understand why 7 interrupts is now valid... Are these not
connected physically?

Best regards,
Krzysztof
