Summary
Add option to the config of GENEVE tunnels to specify the destination port of the tunnel (instead of the IANA default port 6081)
Use case
I'm currently unable to create 2 completely separate tunnel interfaces between the same remote endpoints since both terminate on the same UDP ports. With this option, I could create one tunnel on port 6081 and another one on 6082 for example.
Additional information
The underlying iproute2 package has a parameter "dstport" to configure this: https://manpages.debian.org/testing/iproute2/ip-link.8.en.html#GENEVE
