So i found this manual here:
http://www.silica.com/fileadmin/02_Products/Productdetails/Texas_Instruments/SILICA_TI_66AK2E05-ds.pdf

Glad there is an open document!
There are a couple of ethernet switch chips I can spot there.

Can i control those with "bridge" or say "brctl" utilities?

I can see the bridge ports are exposed and i should be able to
control them via ifconfig or ip link. Thats what "standard
kernel infrastructure" means. Magic hidden in a driver is
not.

Take a look at recent netconf discussion (as well as earlier
referenced discussions):
http://vger.kernel.org/netconf-nf-offload.pdf

Maybe we can help providing you some direction?
The problem is it doesnt seem that the offload specs for
those other pieces are open? e.g how do i add an entry
to the L2 switch?

cheers,
jamal
