I am hoping the box will be able to forward > 30-50Mb/s over its life time. I have just finished a driver for the FORE PCA200E which uses the same NATM stack as the en driver. On a 900MHz Athlon it can send 135MBit/sec with plain AAL5 (this is near to the theoretical maximum) and around 15kbyte/sec over TCP. The TCP sending code seems to be the limiting factor in this case. And well, its -current.
