“trace add dpdk-input 100” ... run a bit of traffic ... “show trace”. That will
tell you precisely what’s happening. Check the outbound src and dst MAC
addresses. It’s quite possible that they have NOT been swapped...

Subject: [vpp-dev] Blackholed packets after forwarding interface output
Hi everyone. I created a plugin for process packet. After process İ forward
packets interface output. For testing, I generate packet with trex and send
vpp. Trex send packet vpp but after process in my node, vpp not send to trex.
But when show int:
TenGigabitEthernet1/0/1 2 up 9000/0/0/0 rx packets
47034936
rx bytes
2822096160
tx packets
47034934
tx bytes
2163606978
it seems to be transfer packet, but not see in trex.

it seem to be received. I cant understand problem.
for trex configuration :
ip route add 16.0.0.0/8 via 10.10.1.2
ip route add 48.0.0.0/8 via 10.10.2.2
Do you have any advice about this problem?
Thanks,
