What you're talking about is Fast-Ethernet which is not that widespread
and the number of Amigas connected to such a net is that small, that you'd
sell perhaps 50 boards/year which does not make up for manufacturing and
developing at all. Another issue is, that a lot of performance get's lost
during the networking-layers (virtual volume -> envoy -> sana.device -> HW).
As an imgae: two stock A3000 connected via Ariadne and Envoy, DiskSpeed
on the other A3000's RAMDISK gives about 300 - 350 KB/s. When you equip
both machines with WarpEngine40/40s, this goes up to well above 600KB/s.
Under NetBSD we had well above 700KB/s throughput with Ariadne...
So what would be the point in having 100MBit/s networking on the hardware
level when the software limits it to below 1 MB/s?
