GIF does not support broadcast
Plus Target Version:
This might be related to #4455.
I am seeing the same radvd spam under System / Routing logs:
Aug 27 20:43:00 radvd 53790 interface gif0 does not support broadcast Aug 27 20:43:00 radvd 53790 do you need to add the UnicastOnly flag?
I don't know how to set that flag from the radvd configuration page.
Unlike #4455, this is not for a VPN connection, but a GIF interface for an IPv6 tunnel.

I found out the issue. I had to:
- change the tunnel IF IPv6 from None to Static
- access the radvd page for the tunnel IF
- change from Managed to Disabled
- revert the tunnel IF IPv6 to None.
This means that there is a bug in pfSense where, even though an interface has its IPv6 address assignment disabled, and the DHCPv6 and radvd pages are hidden, radvd can still be enabled and non-configurable.
