I looked at some similar problem for someone end of April and the
crude workaround was to disable (#if 0) the following code in
in_lltable_lookup():
#if 0
if (!(flags & LLE_IFADDR) &&
in_lltable_rtcheck(ifp, flags, l3addr) != 0)
goto done;
#endif
I had since defered looking at fixing this but finding this thread I
thought I'd just let you know.
