Interface grouping is available on FreeBSD and OpenBSD. This will allow
you to enumerate only SoftEther virtual interfaces or exclude SoftEther
virtual interfaces, and be helpful when making custom scripts to start
DHCP client when virtual interface become up (=VPN connection
established) for example.
Usage examples as follows.
List all interfaces' names available on the system:
```
$ ifconfig -l
vtnet0 lo0 vpn_client0 vpn_client1 vpn_client2
```
Display a list of SoftEther virtual interfaces:
```
$ ifconfig -g softether
vpn_client0
vpn_client1
vpn_client2
```
Display details about SoftEther virtual interfaces that are up:
```
$ ifconfig -a -u -g softether
vpn_client0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

Display details about interfaces except for SoftEther virtual interfaces:
