Objet : [vpp-dev] ipsec packets fragmented post encryption

Hi,
I am on 18.10 and trying to enable reassembly and fragmentation. It is working 
fine for vxlan and vxlan-gpe tunnels but IPSec it is not.
We set physical interface MTU to be 1500 and IPSEC interface MTU to 1350 to 
give room for encryption.

The issue we are seeing is packets are getting fragmented sent out after 
encryption and causing traffic is getting dropped.
Is there any different way to enable fragmentation and then encryption each 
fragment on 18.10.


Thanks in advance.
Sam
