Hello,
we are using VPP 20.01 and vpp-agent in Azure Centos7.5 VM, we have got a
segmentation fault error when we used VPP Agent to set interface MTU.
There is backtrace,
Program received signal SIGSEGV, Segmentation fault.

when Use VPP agent Set interface IP and MTU get the segmentation fault.
docker exec etcd etcdctl put

I would really appriciate any advice.
Thanks.
