Yes, but your fix is removing the handler INT_SOURCE_CSR_TX_FIFO_STATUS which probably should still be handled anyway. > 2) Turns out we are depending on the TX_STA_FIFO register on the card to give us > per-tx statistics, but it appears to only be a sort of global statistic thing > that doesn't even work most of the time.

So basically it gives us crap statistics. I am not seeing this check in the code, only the complete removal of the TX_STA_FIFO handling. > Looking through RaLinks driver it doesn't seem there is a way to get per-tx > statistics, so you can't really tell if the tx failed or not.

Returning success is bogus, it must return status unknown just like the USB drivers do. It is up to rt2x00lib to determine if that should resolve to success or not (at the moment it will resolve to success). > This patch makes it so this driver works for me finally (minus a couple of > quirks).
