[wpan-next,0/6] IEEE 802.15.4 passive scan support

Message

Hello,

We now have the infrastructure to report beacons/PANs, we also have the
capability to transmit MLME commands synchronously. It is time to use
these to implement a proper scan implementation.

There are a few side-changes which are necessary for the soft MAC scan
implementation to compile/work, but nothing big. The two main changes
are:
* The introduction of a user API for managing scans.
* The soft MAC implementation of a scan.

In all the past, current and future submissions, David and Romuald from
Qorvo are credited in various ways (main author, co-author,
suggested-by) depending of the amount of rework that was involved on
each patch, reflecting as much as possible the open-source guidelines we
follow in the kernel. All this effort is made possible thanks to Qorvo
Inc which is pushing towards a featureful upstream WPAN support.

Cheers,
Miquèl
