* libpcap's source, so a number has been chosen that is unlikely to be
* confused with the real one on Linux. Those that are already found in
* Solaris inside <net/if_arp.h> may have a different value to that found
* in Linux but it should be used instead as the Solaris value originates
* from the IANA whereas the Linux values seem to ignore it.
