A bug is found in function arpresolve() in netinet/if_ether.c.
It causes panic when doing ATM due to the (rt0 == NULL).
The following change is supposed for 2.2-SNAP, but it does not work
because struct arpcom has been changed (no more ac_ipaddr member in arpcom).
Please let me know if there is another better way to fix it.
Thanks,
-Jin
