I see the appropriate code in src/sbin/ifconfig/ifpfsync.c

        if (preq.pfsyncr_syncif[0] != '\0') {
                printf("\tpfsync: syncif: %s maxupd: %d\n",
                    preq.pfsyncr_syncif, preq.pfsyncr_maxupdates);
        }

and I can set the maxupd on a pfsync interface:

bash-3.00# ifconfig pfsync0 syncif em0 maxupd 64
bash-3.00# ifconfig pfsync0
pfsync0: flags=0<> mtu 1348
        pfsync: syncif: em0 maxupd: 64

The only thing I can see is that it will not actually display or do
anything unlss there is a syncif set.
