Tool/software:
An issue came up while using iperf3 with the radio trying to measure throughput. It looks like the radio firmware locked up and tripped an internal watchdog:

The observed side effect was the radio stopped responding to iperf traffic for about 15 to 20 seconds, then the radio finally reset (as shown by the kernel log messages above) and then reassociated with the AP. It was a bit concerning because it occurred after about 20 minutes of fairly simple testing with iPerf. Is this a known issue or is there newer radio firmware and/or driver available with more recent improvements or bug fixes?
