Hi,

Tested on bananapi-r64 with an mt7612 in slot cn8 and compex wle900vx in cn25.

note that there are pcie-HW-issues on my boards revision(power limitation and missing capacitors on tx-lines) which may cause the different Pcie-Ids for mt7612 and the class of the compex-card. sorry had not seen this before on tests with Steven

maybe anyone can test the Patches with a fixed board.
