Huh? I thought the ARP table is integrated with the routing
table in all 4.4BSD-derived systems, and the routing table
entries are dynamically allocated with malloc().

PS: A short browse through the source yields very few positions
depending on the GATEWAY option (thanks to id-utils):
  The default value for NMBCLUSTERS depends on the GATEWAY option.
  If NMBCLUSTERS is defined before, that doesn't matter.
  #ifdef GATEWAY, more arp hash buckets, as well as more entries
  per bucket are allocated.
  That looks very ugly -- why does netatalk not do arp the same way

  #ifdef GATEWAY and #ifndef IPFORWARDING, default ip-forwarding
