Hi Stephen,

Thanks!

Felix made me aware of this yesterday evening and said he's going to
work out the required changes to mt76.

Kalle and I will make sure to submit the trees to Dave one by one so he
doesn't have to deal with it :)

Unfortunately, this might take a few days to resolve.

Looks pretty much right to me - perhaps for safety there should be a
NULL check on txq, but OTOH when you get here it should be non-NULL.

Sorry for the inconvenience, I hadn't realized mt76 went in now.
