Thanks for the replies guys.
I don't know what FreeBSD is doing in their TCP stack to support TCP
Offload - I haven't looked at that part of FreeBSD. I suppose once I
get the NIC driver working (without memory leaks), I could delve into
the a little bit. It sounds like adding this to the NetBSD TCP stack
might be a bit more cumbersome than I would hope?
