6bdf1e0efb Makefile: drop -D__CHECK_ENDIAN__ from cflags
That's the default now, no need for makefiles to set it.

1201cd22fd mac802154: introduce mac802154_config_ops
This patch introduces mac802154_config_ops struct. Like wireless this
struct should be the only one interface between ieee802154 to mac802154
or possible HardMAC drivers.

b9ff77e50c mac802154: monitor: merge into iface implementation
This patch removes the monitor implementation file and put all monitor
stuff into iface file. It's now small enough to put all necessary
handling into iface.

c208510351 mac802154: add netdev qeue helpers
This patch adds a new file net/mac802154/util.c which contains utility
functions for drivers, etc. This file contains functions to start and
stop queues for all virtual interfaces, this is useful for asynchronous
handling by driver level.

15859a5e14 mac802154: move wpan.c to iface.c
The wpan.c file contains the interface handling functions now. It's similar
like the mac80211 iface.c file. This patch renames this file to iface.c to
have similar naming convention in mac802154.

62eb01f5c2 mac802154: move ieee802154_dev.c to main.c
The ieee802154_dev functionality contains various function for
allocation and registration of an ieee802154_dev. This is equal to the
net/mac80211/main.c file. This patch rename the ieee802154_dev.c to
main.c to have the same behaviour.

5d637d5aab mac802154: add llsec structures and mutators
This patch adds containers and mutators for the major ieee802154_llsec
structures to mac802154. Most of the (rather simple) ieee802154_llsec
structs are wrapped only to provide an rcu_head for orderly disposal,
but some structs - llsec keys notably - require more complex
bookkeeping.

Since each llsec key may be referenced by a number of llsec key table
entries (with differing key ids, but the same actual key), we want to
save memory and not allocate crypto transforms for each entry in the
table. Thus, the mac802154 llsec key is reference-counted instead.
Further, each key will have four associated crypto transforms - three
CCM transforms for the authsizes 4/8/16 and one CTR transform for
unauthenticated encryption. If we had a CCM* transform that allowed
authsize 0, and authsize as part of requests instead of transforms, this
would not be necessary.

b70ab2e87f ieee802154: enforce consistent endianness in the 802.15.4 stack
Enable sparse warnings about endianness, replace the remaining fields
regarding network operations without explicit endianness annotations
with such that are annotated, and propagate this through the entire
stack.

Uses of ieee802154_addr_sa are not changed yet, this patch is only
concerned with all other fields (such as address filters, operation
parameters and the likes).

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.

This interface could be used by networks sniffers and is already
