[Avila] Too many ethernet interrupts on Gateworks board

Tim,

63mbps over a 54mps standard is impressive!

I just followed demo scripts on the avila board to
setup a simple 802.11G AP mode ATH0, add ATH0 and ETH0
to the linux bridge and use a TCP program to send
packets (1500 MTU) from one computer (associated to
ATH0) to another (connected to ETH0). The ASUS WL-530g
gets 21-22mps. Gateworks 15-16mps. A Linksys router
comes in at 23mps.

Maybe I'm doing some thing wrong with the standard
development kit from Gateworks?  I haven't started
tweaking anything yet.

Regards
