+           Non-temporary proxy ARP entries for  an IPMP group are
+           automatically managed by the kernel.  Specifically, if
+           the hardware address  in an entry matches the hardware
+           address of an IP  interface in an  IPMP group, and the
+           IP  address is not local to   the system, this will be
+           regarded as an IPMP proxy  ARP entry.  This entry will
+           have  its hardware address  automatically adjusted  in
+           order to keep the IP address  reachable so long as the
+           IPMP group has not entirely failed.
 
+           ARP entries  must be consistent  across an IPMP group.
+           Therefore, ARP   entries  cannot be   associated  with
+           individual underlying  IP interfaces in an IPMP group,
+           and must  instead be associated with the corresponding
+           IPMP IP interface.
