Comment (by risa2000):
I went ahead and changed my `/etc/config/network` to:
{{{
config interface vpn
option ifname tun0
option proto static
option auto 0
}}}
but I see the same behavior as described above. No IP address assigned on
`tun0` interface:
{{{
root@risa-wrt:~# ip addr
5: tun0: <POINTOPOINT,MULTICAST,NOARP> mtu 1500 qdisc fq_codel state DOWN
group default qlen 100
link/none
}}}
even though `openvpn` believes it did a correct job:

}}}
The only difference compared to the original configuration with `proto
none` is the state of `tun0` interface after the boot (it is `DOWN`).
I am on r47874.
