something like this:

sys/netinet/ip_fw.c:
static u_int64_t seq_num = 0;
SYSCTL_INT(_net_inet_ip_fw, OID_AUTO, seq_num, CTLFLAG_RW,
    &seq_num, 0, "Sequence number of changes");

static int
ip_fw_ctl(struct sockopt *sopt)
{
    [...]
    case IP_FW_FLUSH:
        seq_num++;
        [...]
    case IP_FW_ADD:
        seq_num++;
        [...]
    case IP_FW_DEL:
        seq_num++;
....
}

it's should be useful to have similar counter for dummynet.


regards,
m.
