I tried wireguard-go on OpenBSD and FreeBSD. I want to use WireGuard as 
replacement for OpenVPN point to point tunnels with dynamic routing 
(OSPF, iBGP). Especially this requires the right interface flags for the 
tun interface. So far wireguard-go on *BSD configures the tun interfaces 
as multicast incapable, broadcast interface which confuses the OpenBSD 
OSPF daemon completely and doesn't make any sense for a point to point 
tunnel. I get that wireguard-go tries to fake point to multipoint 
support that way. Is there a better solution than changing the hardwired 
argument ioctl() in tun/tun_*bsd.go?
