It should be noted that I was able to saturate a 100 Mbps Ethernet with
FreeBSD 2.2 and a 21140 based card, using around 56% of the CPU of a
PPro-200. This was done almost exactly three years ago, using the (then)
standard if_de driver. I have no idea whether the card was operating in
store-and-forward mode or not - but the performance was perfectly fine.
