That is total fiction - I wrote a lot of the code that passes that signal
through to the upper layers. The only way to test the connection is via data
throughput. As most driver/card combinations are faster than the external link,
you also need a local server running iperf or tcpperf.

You are comparing different kernels. The driver is better with time.

If you were running a full upload while trying to use Skype or any other VOIP
application, you would experience delays. With the openfwwf, all transmits use a
single hardware queue, whereas the proprietary firmware uses all 4 of the
hardware queues with the high-priority one reserved for time-critical applications.

Thanks for the offer, but we have provided lots of driver dumps to the
open-firmware group. They are still looking for the bug.
