Thanks!
But those examples are for same MTU for client and server. If we have
Client: 1500

The size of MTU only really matters for the server and client. The
between connections need to be larger than the packets that are being sent.
Scenario 1:
Server - 1400 MTU
Client - 1400 MTU
Switches - 9216 MTU
OVS - 1500 MTU
Result: Successful - Traffic passes without any issue
Scenario 2:
Hello.
We've hit badly changes in behaviour of OVS when we switched from 3.08
to 3.13 kernel. When runs on 3.11 or above, OVS starts to use kernel
GRE services. And they copy DNF (do not fragment) flag from encapsulated
packet to GRE packet. And this mess up all things, because ICMP messages
