Hi Kalle,
Unfortunately I found a regression introduced by this patch for mt7663u (and I
guess for mt7921s as well). Do you want me to post a fix or just a v2?
Sorry for the noise.
@Sean: can you please test the following patch on mt7921s? (I do not have the hw).
Regards,
Lorenzo

I don't rebase my trees, so please post a fix. I was planning to submit
a pull request to net tree today, but is this so serious that I should
skip that?

I have already tested mt7663u but I do not have mt7921s hw for testing (but the
behaviour should be the same). I guess we can split the patch, just post the
fix for mt7663u and let Sean the time to test it on mt7921s (I am not sure
mt7921s is already available on the market). In this way you can send the PR
today. What do you think?

Lorenzo

I think it's best to wait, I prefer to have proper build testing on my
tree before I submit the pull request.
