Non-PCI gigabit Ethernet controller

Thanks Scott. I agree with you that adding a bridge is a silly idea.
Marvell has not got a non-PCI version gigabit Ethernet either. I guess
we just wait.

You'll be waiting a long time.  There's no market for a gigabit 
controller that can only do 10% throughput because of its bus.  Have you 
noticed only 3 products even exist for non-PCI 100Mbps?

If you want bragging rights for gigabit in your design, it looks like 
you'll need to use a PCI bridge, wait for an integrated MCU, or switch 
to an MCU with PCI.

Did you study any (early) 1 GbE switch or other 1 Gb network
component? You might find some useful hints about the chips used.
Modern 1 Gb switches most likely contain only ASICs, so they are not
of any use in your case.

I gave up on the gigabits now.

Can you list the three providers of the non-PCI 100Mbps? I only knew
this one:

(That's a 10Mb model; I suspect you meant the one below.)

Here are the three, in rough order of their apparent popularity:

The Asix has the benefit of being an NE2000 interface, which gives you 
no shortage of reference drivers.  It's been on the scene for about 3 
years now, and it's becoming pretty popular, at least relatively speaking.

For a proto board of the Asix, go to http://www.edtp.com.  Good folks, 
and it's cheaper than ordering a sample from Taiwan.  They'll also sell 
bare chips if their stock isn't low.

Cheers,
Richard
