[wpan-tools,0/7] IEEE 802.15.4 passive scan support

Message

Hello,

This series follows the work done in the Linux kernel stack: now that
the core knows about the different netlink commands and attributes in
order to support passive scan requests from end-to-end, here are the
userspace changes to be able to use it.

Here is a list of the new available features.

* Passively sending (or stopping) beacons. So far only intervals ranging
  from 0 to 14 are valid. Bigger values would request the PAN
  coordinator to answer to BEACONS_REQ (active scans), this is not
  supported yet.
  # iwpan dev wpan0 beacons send interval 2
  # iwpan dev wpan0 beacons stop

* Scanning all the channels or only a subset:
  # iwpan dev wpan1 scan type passive duration 3

* If a beacon is received during this operation the internal PAN list is
  updated and can be dumped or flushed with:
  # iwpan dev wpan1 pans dump
  PAN 0xffff (on wpan1)
	coordinator 0x2efefdd4cdbf9330
	page 0
	channel 13
	superframe spec. 0xcf22
	LQI 0
	seen 7156ms ago
  # iwpan dev wpan1 pans flush

* It is also possible to monitor the events with:
  # iwpan event

* As well as triggering a non blocking scan:
  # iwpan dev wpan1 scan trigger type passive duration 3
  # iwpan dev wpan1 scan done
  # iwpan dev wpan1 scan abort

Cheers,
Miquèl

Hi,

I did a quick overlook of those patches and I am very happy to see
such patches and I will try them out in the next few days! Thanks.

I think those binaries were added by accident, or?

Sure, thanks for the feedback all along this series, I'll try to
discuss and address all the points you raised.

Oops! Of course I'll drop them all.

Thanks,
