The sources to the wired networking are available in Linksys source
package. AFAIK, Linux should detect and use the wired interface in the
MIPS core out of the box. The switch sources are not in the vanilla
tree, but are available. OpenWrt has them in the 2.4 sources, not sure
if they are usable in 2.6 as well, but I don't see any reason why they
shouldn't be.
So, wired network should work fine with 2.6 kernel. Problem with binary
blob is only with the wireless, and CFE won't help here.
If you don't want/need wireless, go for 2.6. But I don't suppose anyone
would buy WRT610N to use it as a gigabit switch. There are cheaper
solutions out there...

Okay, so digging around I see that the networking for the 2.6 series
kernel is being held up by the fact that linksys has only released 2.4
series kernel firmwares that contain binary blobs for talking to the
broadcom chips. Bummer.
I've found this [1] (CFE bootloader source code), which appears to be
a BSD-like license. It has source for interacting with the wired
chipset in
cfe-1.4.2/cfe/dev/{bcm5700.h,dev_bcm5700.c,dev_bcm5780_ht1000.c}. I
don't think this source is the same version as what is on my WRT610N
based on the following:

### End ###########################################################
Basically:
CFE version 1.0.37 for BCM947XX (32bit,SP,LE)
and
Boot version: v4.2
But the above mentioned files may provide enough info to modify the
tg3 driver successfully... I'm not familiar enough with the guts of
this stuff to know if I have the right thing.
Any pointers before I wrecklessly dive in and break things?
thx,
Jason.
