There are a few out there.  The entire Excelan line (now being sold
by Federal Technologies), Interlan, and probably a couple more.

Typically this is a slower solution than host based protocols.  Why?
Because in order to keep the price down, the on board processor, the
one that runs your TCP/IP stack, is slow.  Typically a 6-12 Mhz 80186.
This is a lot slower than a 25+ Mhz 80486/R3000/SPARC/RS6000/PA-RISC/...
when it comes to fiddling bits and computing a checksum!

In general, there is no reason why this architecture cannot give you
equal or better performance that a host-based scheme, but you have to
put a *real* cpu on the network board.  If you find one, expect to pay
big bucks.
