Right - I forgot to mention that while the PCI card produced about 60% CPU
load (at full speed), the PCMCIA card in the net4511 loaded it to 100% (as
indicated by top, which became almost unusable while transferring data at
full speed).

I'd like to know what you can get out of a net4521, too... So far I have
the impression that transferring data from/to a wireless card is very
expensive (CPU-wise) in any case - a net4501 can pump up to 60 Mbps
between two of its NICs (with fast routing and polling enabled, though -
without these it's still > 40 Mbps). Looks as if wireless cards would
still use PIO. ;)

Also, I wonder how other BSDs or Linux compare. At least in Ethernet
performance, FreeBSD seems to be superior to NetBSD and OpenBSD on net45xx
(I posted some benchmarks to the soekris-tech list a while ago),
performing as good as Linux.
