 src/dist/tcpdump/interface.h has:
 
 /*
  * The default snapshot length.  This value allows most printers to print
  * useful information while keeping the amount of unwanted data down.
  */
 #ifndef INET6
 #define DEFAULT_SNAPLEN 68      /* ether + IPv4 + TCP + 14 */
 #else
 #define DEFAULT_SNAPLEN 96      /* ether + IPv6 + TCP + 22 */
 #endif
 
 I wonder where the problem is.
 INET6 is defined in src/usr.sbin/tcpdump/Makefile
 
 Do you have USE_INET6=no??
