Guysm

Yet another network driver is probably not what the world needs most,
but I had to write one for MIPS Linux this month that was a little
different from any of the others.  It's a driver that impersonates
an ethernet interface whilst actually passing packets in memory between
different processors running different OS images in a shared memory
environment, something that actually happens in embedded systems.
I call it M3P (pronounced "mep"), for MIPS Memory Message Passing,
but if I didn't think it could be adapted to non-MIPS based and indeed
heterogeneous systems, I wouldn't trouble you with it.  I note that
the "mipsnet" driver, which is limited in its function to running
on a MIPS simulator, made it in, so I figured I'd at least ask if
it's something that could be absorbed into the network driver mass,
the better for other folks to improve on it - there are a lot of
enhancements I'd like to make, some of which are described in the
comments, but it's not clear that I'll have time to make them any
time soon.  A familiar refrain, I suppose.  Anyway, the patch is
attached.  See also Ralf's ack below.
