Since I needed an |ifconfig| with a more BSD-like interface /anyway/ so 
that I didn't have to maintain highly divergent scripts, you are going 
to gain in the future.

|ifconfig| from GNU inetutils 
<https://packages.debian.org/en/sid/inetutils-tools>:

    jdebp % inetutils-ifconfig -l
    enp14s0 enp15s0 lo
    jdebp % inetutils-ifconfig lo
    lo        Link encap:Local Loopback
               inet addr:127.0.0.1  Bcast:0.0.0.0  Mask:255.0.0.0
               UP LOOPBACK RUNNING  MTU:65536  Metric:1
               RX packets:9087 errors:0 dropped:0 overruns:0 frame:0
               TX packets:9087 errors:0 dropped:0 overruns:0 carrier:0
               collisions:0 txqueuelen:1000
               RX bytes:51214341  TX bytes:51214341

    jdebp %

|ifconfig| from NET-3 net-tools 
<https://packages.debian.org/en/sid/net-tools>:

    jdebp % ifconfig -l
    ifconfig: option `-l' not recognised.
    ifconfig: `--help' gives usage information.
    jdebp % ifconfig lo
    lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536

|ifconfig| from an unreleased version of the nosh toolset 
<http://jdebp.eu./Softwares/nosh/>:

    jdebp % ifconfig -l

    jdebp % ifconfig lo

FreeBSD |ifconfig| (on a different system) for comparison:

    JdeBP % ifconfig lo0
    lo0: flags=ffde8149<UP,LOOPBACK,RUNNING,PROMISC,MULTICAST,PPROMISC,MONITOR,STATICARP> metric 0 mtu 16384

The |ifconfig| from an unreleased version of the nosh toolset
