This is about being able to ping the USB-attached node on its link-local<br>
address on the USB interface from the host. When nimble or 802154 are<br>
added, these addresses are the same, but they stay in `TNT[1]`<br>
indefinitely (ok, at least 5') rather than being VAL.<br>

That'd be a plausible explanation, given that unlike the others it does<br>
need to wait for the host. (And I don't have a setup where I can hotplug<br>
that w/o power cycling the whole device). I tried `ifconfig 11 set state<br>
reset`, but `unable to set status`.<br>
