I don't think these are linked at all. While being able to specify
multiple listen ports, I agree, is a good idea, being able to specify
alternate remote ports is needed because you can already change the
one per-host port.

With only one listen port per host, if they are different on two hosts,
NDA_PORT in the fdb table is the only way those two hosts can use VXLAN
with each other at all.

It has nothing to do with how many listen ports there are, but just that
the listen port can be different on different hosts.
