I believe you wanted to say "frame" instead of packet and "64" instead of "60"? As far as I know, an IP packet can transport no payload, which gives a 20-bytes packet in result. :-P
The limitation is about the minimum size of the frame, which (on ethernet) is of 64 bytes, to allow proper collision detection... (I hoped that such low-layer stuff would be handled by the packet driver... seems that it is not...)

All in all, mTCP sounds like a great project. It's really nice to see that someone still cares to write some good stuff for DOS! :-)
