PCI Cogent Ethernet and Fast Ethernet adapters are very good.
We get 60% of a 100mbits link using UDP. These are not
supported on the release, but you could get the information to
write a driver from Digital Semiconductor
(DECchip 21140A PCI Fast ethenet Lan Controller).
The interface is very similar to a lance controller
and it does scatther send (up to two).
