There are no options that control that; support for that is not
conditionally compiled.

Either

        1) your application isn't linked with that version of the
           library;

        2) your Linux defines ARPHRD_IEEE80211 as something other than
           801 in "/usr/include/net/if_arp.h";

        3) including <net/if_arp.h> when building libpcap doesn't cause
           it to include "/usr/include/net/if_arp.h".
