1e9f954516 mac802154: fix destructon ordering for ieee802154 devices
mutex_destroy() must be called before wpan_phy_free(), because it puts the last
reference and frees memory. Catched as overwritten poison in kmalloc-2048.

32bad7e30f mac802154: add wpan device-class support
Every real 802.15.4 transceiver, which works with software MAC layer,
can be classified as a wpan device in this stack. So the wpan device
implementation provides missing link in datapath between the device
drivers and the Linux network queue.

According to the IEEE 802.15.4 standard each packet can be one of the
following types:
 - beacon
 - MAC layer command
 - ACK
 - data

This patch adds support for the data packet-type only, but this is
enough to perform data transmission and receiving over radio.

0606069d9e mac802154: monitor device support
Support for monitor device intended to capture all the network activity.
This interface could be used by networks sniffers and is already
supported by WireShark. That's a good test point to check that basic
MAC support works.

1010f54018 mac802154: allocation of ieee802154 device
An interface to allocate and register ieee802154 compatible device.
The allocated device has the following representation in memory:

	+-----------------------+
	| struct wpan_phy       |
	+-----------------------+
	| struct mac802154_priv |
	+-----------------------+
	| driver's private data |
	+-----------------------+

Used by device drivers to register new instance in the stack.
