FYI "Dropping frame due to full tx queue" causes "arrived at non-free entry" eventually that freezes interface so only reboot helps, removing "Dropping frame due to full tx queue" from printing to logs prevents this kind of hung and is better solution than 5 patches. oh and don't forget to add note that rt2x00_err/rt2x00_dbg prints can cause serious bug so you don't acidentally enable them again in a year or two! > Also 'result in lower throughput' is over-generalized statement.
