BTW, just for the record, the culprit to disk corruption on ath9k
seems to be a bug in the swiotlb emergency buffer. If bored please
bugzilla 11811 [1] for more information and also a suggested patch
for how to fix this by Maciej, which he should be sending to
linux-kernel soon hopefully.

The swiotlb issue should not affect us anymore though as we now don't starve
the swiotlb of bounce buffers and hence no reason to rely on the buggy
emergency buffer.
