i also tracked this down, when i was experimenting with wampes while
attaching to the soundmodem sm0-device (something, that worked under
kernel 2.0.x).
again, i saw it, while debuging krnlif.c (attaching to the kernel ip from
wampes, that stopped working when 2.2.x kernels came up (SOCK_PACKET problem)).
and last but not least, while testing the bpq0 features (ax25 over ethernet
mac layer), i saw these messages.
i must admit, that i never understood, what's *really* going on,
but i found exactly that piece of code.
well, the author sais "Code, following below is wrong. [...] so that the
second statement is just protection against buggy protocols.", and i
believed it was a hack to make things work, and may be rewritten some time..
hmm..
