Subject: [PATCH wpan/next v4 0/8] net: ieee802154: Improve filtering support

Hello,

A fourth version of this series, where we try to improve filtering
support to ease scan integration. Will then come a short series about
the coordinator interfaces and then the proper scan series.

Thanks,
Miquèl

Changes in v4:
* Added a condition upon which the packets for a given interface would be
  dropped: in case AACK and/or address filtering was expected, but
  another interface has disabled it on the PHY.
* Changed the way Alexander's patch behaves regarding the handling of
  the different filtering levels. I added a third variable which shows
  the default filtering level for the interface. There is a second
  (per-interface) field giving the expected filtering level for this
  interface and finally we keep the per-PHY actual filtering level
  information. With this we can safely go back to the right level after
  a scan and also we can detect any wrong situation where ACKs would not
  be sent while expected and drop the frames if in this situation.
* Moved all the additional filtering logic out of the core and put it
  into hwsim's in-driver receive path, so that it can act like any other
  transceiver depending on the filtering level requested.
* Dropped the addition of the support for the ieee802154 promiscuous
  filtering mode which is anyway not usable yet.
* Dropped the "net:" prefixes in many patches to fit what Alexander
  does.

Changes in v3:
* Full rework of the way the promiscuous mode is handled, with new
  filtering levels, one per-phy and the actual one on the device.
* Dropped all the manual acking, everything is happenging on hardware.
* Better handling of the Acks in atusb to report the trac status.
