Traffic not going through dummynet

[hiren panchasara]

This is driving me nuts. I've had an ipfw/dummynet working config on
separate setup and the same thing doesn't work on this new setup I have
so I tried to narrow it down and removed all complexity and trying to
see if this works on just single host. But it doesn't work as I expect
it to. I am pretty sure I am missing something here.

11.0-CURRENT FreeBSD 11.0-CURRENT #1 r283696M: Fri Jul 17 15:43:05 MST
2015

loader.conf has:
net.inet.ip.fw.default_to_accept="1"
dummynet_load="YES"

I did:
# ipfw add pipe 1 ip from any to any
# ipfw pipe 1 config delay 100ms

# ipfw show
00100    0      0 pipe 1 ip from any to any
65535 4321 509541 allow ip from any to any

# ipfw pipe show
00001: unlimited       100 ms burst 0 
q131073  50 sl. 0 flows (1 buckets) sched 65537 weight 0 lmax 0 pri 0
droptail
 sched 65537 type FIFO flags 0x0 0 buckets 0 active

Now if I ping anything, I don't see 100ms delay.

# sysctl -a | grep ipfw
kern.features.ipfw_ctl3: 1
net.link.ether.ipfw: 0

net.inet.ip.dummynet.io_pkt_fast: 0
net.inet.ip.dummynet.io_fast: 0
net.link.ether.ipfw: 0

What should I be looking at next?

Cheers,
Hiren
