Subject: MTU in vpp
Hi
I set mtu to all of my interfaces using "vppctl set interface mtu 1500
<interface>".
But when I generate packets larger than mtu size, all packet pass through vpp.
Is there any parameter that I must set?
I generate large packet using "ping -M do -s 9472 200.200.200.40".
My vpp version: master v18.07-rc0~147-g7220f42c
Thanks,
Sincerely
