Kuniyuki Iwashima says:

====================
geneve: Allow binding UDP socket to a specific address.

By default, a GENEVE device bind()s its underlying UDP socket(s) to
the IPv4 or IPv6 wildcard address because there is no way to specify
a specific local IP address to bind() to.

This prevents deploying multiple GENEVE devices on a multi-homed host
where each device should be isolated and bound to a different local IP
address on the same UDP port.

This series introduces two options to specify local IPv4 or IPv6
addresses for a GENEVE device.
