The linux-x25 mail list has stopped working for a long time.

I think we only decided that X.25 as a whole was still needed. We
didn't decide that this particular driver was necessary.

I think this driver never worked. Looking at the original code in
Linux 2.1.31, it already has the problems I fixed in commit
8fdcabeac398.

I guess when people (or bots) say they "tested", they have not
necessarily used this driver to actually try transporting data. They
may just have tested open/close, etc. to confirm that the particular
problem/issue they saw had been fixed.
