I too am suffering the same. There have been several suggestions,
mainly around the arp_ entries in the /proc/sys/net/ipv4 directory. Sadly
on my 2.2.10 (SuSE) with libax25 (0.0.7), tools (0.0.5) and apps
(0.0.4), there are no arp entries anywhere under /proc (besides a copy
of the arp table itself). My older kernels (2.0.35) did have these entries
and they worked fine. I've checked the older SuSE 6.1 with 2.2.5 and
they're not there either.

Does anyone have any suggestions as to if it's something I've done or
are they not there in 2.2 even though the linux/net/Documentation says
they should be.

I've tried echoing values to create the entries, but no joy....

Any ideas?
