exciting news: thanks to a contribution by Roger Burrows we now have an open-source STinG driver for the USB-to-Ethernet adapters based on the Asix AX88772 chip -- the same ones that are supported by the MiNTNet driver and my uip-tool port. STinG (ST Internet Next Generation
), if you don't know, is probably the most popular network stack for plain TOS, for which different clients (FTP, Mail, IRC, WWW...) exist.

Of course, I tested it with my Lightning VME USB host adapter. However, since troed got my uip-tool port working on the Unicorn, I assume the STinG driver would work with that as well.
