for example, if TOE was supported in a driver (eg. /dev/toeN) which allowed
user-space to mmap() into RAM (either on the card or main memory which the
TOE card DMAs into/out-of).

This is a very old concept, see UNET.

But that is %100 outside the realm of the TCP on a card stuff.
You don't even need firmware to do UNET, you just export the
packet descriptor rings into userspace. Like I said, it's a
"been there, done that" technology.

Franks a lot,
