for the pc architechture, this is certianly true.  i would even bias
development toward 10 and 40gbe.

but for other platforms, i think 10/100 chipsets make a lot of sense
today.  10/100 is great for appliance-ish applications/
for example, this is a very interesting bit of hardware
(sorry, ron, mips, not arm)

an ethernet driver is here

	https://dev.openwrt.org/browser/trunk/target/linux/atheros/patches-2.6.33/110-ar2313_ethernet.patch?rev=19906

it's a mere 1200 lines, which is just trivial in the linux world so if one
were to scare up documentation, it might be quite a dream to
program.

there were a few others i stumbled on recently.  i recall reading
the datasheets for a few spi-based chipsets that looked pretty clean.
(obviously 10mbps.)
