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.
regards Frank
Hi Frank,
We've verified the patchset on a fixed board.
The result shows that no matter how I swap the cards, it all works fine :)
Here are the logs:
