Hi,
I'm having some problem to make traffic shaping work with bridge, the
topology is below, the same script to set the delay/loss works for
10.34.201.45 and 10.35.201.47, but not working
for 10.35.200.2.
I use ifb device for traffic control, say for example, adding 300ms delay
for dst 10.35.200.2, and I use tcpdump to capture ifb1, and no packets. And
if I set the dst to 10.35.201.47 or 10.35.201.45, it works.
I tried to read the code, the "sch_handle_ingress" is before "rx_handle",
and I can capture packets on enp2s0, but can't figure out why the filter is
not working, 10.35.200.2 is in different subnet with 10.35.201.45, but the
bridge works b/c it just use MAC address, even it's not the typical
scenario to put them in different subnet.
Thanks in advance!
