The good: - Switching off the radio and back on finally works - nice work. - Scanning seems faster (but see caveat below) - Association is MUCH faster (mind you, I don't use an encrypted AP). - The "failed to align memory" stuff when the driver loads up - fixed. - The fact that it reloaded in the kernel even if I manually kldunloaded if_wpi.ko - fixed The slightly wonky: - As reported by someone else: wpi0: timeout resetting Tx ring 1 wpi0: timeout resetting Tx ring 3 wpi0: timeout resetting Tx ring 4 appear on startup and occasionally on kldload - however they don't appear to adversely affect too much The ugly: - I can only do an ifconfig wpi0 scan every OTHER time - in between successful attempts, I get wpi0: fatal firmware error wpi0: timeout resetting Tx ring (or: timeout resetting Tx ring 0) wpi0: link state changed to DOWN This wouldn't be so bad since it works every other time, but the problem is that every time I do a scan, it sets the link state down, causing the connection to drop - doesn't seem normal. Of course then it comes right back up but the network interruption is not so great. Hmm - what else? The whole thing seems - livelier. I need to run some throughput benchmarks but traffic to/from the card on my local network seems faster and more responsive. Hopefully this isn't the placebo effect. ;) Great work to you & rest of team on this patch... it's more than usable at this point! --Yousif
