PATCH v2 1/1 Show 'external' link mode in output

Recently external support was added to the tunnel drivers, but there is no way to introspect this from userspace. This adds support for that.

Now ip -details link shows it:

```
7: tunl60@NONE: <NOARP> mtu 1452 qdisc noop state DOWN mode DEFAULT group
default qlen 1
    link/tunnel6 :: brd :: promiscuity 0
    ip6tnl external any remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) addrgenmode eui64 numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535
```
