Hi all, I've been working on the TX underrun issues that I've only just noticed! * I've just made the TX underrun and TX FIFO adjustment code in the driver match what the reference driver does. * That is, the thresholds that are being used for when to start refilling the TX FIFO now match what the reference driver does for the AR5416 and later chips, rather than using the same thresholds as the AR5212. * I've also fixed the 11n TX delimiter / TX data underrun statistics. The TX FIFO underrun statistics were already okay. * I haven't yet updated the earlier HAL code to properly enable the URN interrupt for pre-11n chips; I'll do that soon. I'd appreciate it if people would update their devices to the most recent -HEAD and do some iperf testing, just to make sure things aren't entirely broken. I've done some initial testing on my local devices but nothing thorough. You'll see TX FIFO, data and delimiter underruns show up in athstats. Thanks! Adrian
