Hi,
I install ovs and ovn for version of 2.11.4. and use geneve protocol for
overlay communication. and found some log info in ovs-vswitch.log, like
bellow:

with the log info it tell me my kernel doesn't support several modules,
what can i do to let the kernel support them. also i found some warn
message like below:

messages. thank you very much.
