I did some more benchmarking as Jeff Garzik requested:
[S: sending host, R: receiving host]
1. S: Broadcom's GPLed driver
R: Miller/Garzik's GPLed driver
2. S: Broadcom's GPLed driver
R: Broadcom's GPLed driver
3. S: Miller/Garzik's GPLed driver
R: Broadcom's GPLed driver
(scenario 4, Miller/Garzik on both ends has already been tested, see another
email in this thread).
