Oh, that's not the problem. This is where the v6 patches have
relevance: carrying v6 involves inventing a way to tag packets with
types; I used one of them for v6, and it would be easy to use another
for serial data. The difficulty is in the kernel: SLIP works by
switching line disciplines, which makes it difficult to get normal
output processing to happen - and what I want is for that to happen and
then run the result through if_sl.c before sending it to the real
In the light of morning, I'm not sure this will get me what I want even
if I make it work. I need to think about it more....
