Hello there,

I am using OpenBSD with OpenBGPD to server my private ASN. Unfortunately, since 
upgrading from 7.0 to 7.1, my p-to-p vxlan underlay network stopped working. 
This behavior is reproducible on fresh set up systems without any further 
modification.
My configuration looks as follows on both sides with correct IP addresses:
```
# content of /etc/hostname.vxlan0
up
tunnel 1.1.1.1 2.2.2.2
inet6 2001:db8::1/126
vnetid 10
```
While taking the interface up, I am getting the following error:
```
border1# ifconfig vxlan0 up 
ifconfig: SIOCSIFFLAGS: Protocol not supported
```
If someone has an idea, please let me know.

Best regards
Florian
