Oh?
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html#latest
doesn't mention that, AFAICT.
Also, iw _requires_ nl80211.  I know this because it did not work for me.
(ie, iw IS NOT a replacement for wireless-tools)

(OT, I usually use iwmulticall, the multicall version of wireless-tools)

Yuck.  One monolith that does everything but no plugin architecture...

Well, if toybox implements ifconfig, there will be work done on ifconfig.
I won't be switching.  And Rob won't be.  And Android won't be.

In other words, if you're switching, who cares?  If you want an ip command, please either write it yourself or pay for it to happen. It's not on Rob's agenda at present, and this argument over whether to implement it or ifconfig is making no headway and impeding real progress.

mount and init have specs in LSB--though it's not enough.
Landley's point is that toybox aims to be standards-conformant, not to copy every command in every detail. And if you can point to a standard (POSIX, LSB, or similar, not "consensus among a subset of distros" which would also mandate avahi for zeroconf and pulse for audio) that says "use ip", then that will mandate implementing ip.

As far as I can tell, that problem is only with the net-tools implementation of ifconfig. BSD still uses ifconfig, and so does Android.
