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.
