Just try to make it clear.

The support for ioctl SIOCSTUNFIB ( ifconfig vxlan[N] tunnelfib x ) was added 
via commit https://cgit.freebsd.org/src/commit/?id=7f7a804ae077 
<https://cgit.freebsd.org/src/commit/?id=7f7a804ae077> . 
The man page of ifconfig(8) was updated to reflect the change, but vxlan(4) was 
not.

Well by default the tunnelfib of a vxlan(4) interface is 0 ( the system's 
default fib ) and is not displayed. If you set it to a fib number other than 0, 
ifconfig(8) will show that.

```
# ifconfig vxlan0
vxlan0: flags=1008802<BROADCAST,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1470
        options=80020<JUMBO_MTU,LINKSTATE>
        ether 58:9c:fc:00:7c:2c
        groups: vxlan
        media: Ethernet autoselect (autoselect <full-duplex>)
        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

# sysctl net.fibs=2
net.fibs: 1 -> 2

# ifconfig vxlan0 tunnelfib 1
# ifconfig vxlan0
vxlan0: flags=1008802<BROADCAST,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1470
        options=80020<JUMBO_MTU,LINKSTATE>
        ether 58:9c:fc:00:7c:2c
        groups: vxlan
        tunnelfib: 1
        media: Ethernet autoselect (autoselect <full-duplex>)
        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
```
