c38383530f mac802154: tx: fix synced xmit deadlock
This patch reverts 6001d52 ("mac802154: tx: don't allow if down while
sync tx"). This has side effects with stop callback which flush the
transmit workqueue. The stop callback will wait until the workqueue is
flushed and holding the rtnl lock. That means it can happen that the stop
callback waits forever because it try to lock the rtnl mutex which is
already hold by stop callback.

32b23550ad ieee802154: change cca ed level to mbm
This patch change the handling of cca energy detection level from dbm to
mbm. This prepares to handle floating point cca energy detection levels
values. The old netlink 802.15.4 will convert the dbm value to mbm for
handling backward compatibility.

1a19cb680b ieee802154: change transmit power to s32
This patch change the transmit power from s8 to s32. This prepares to store a
mbm value instead dbm inside the transmit power variable. The old
interface keep the a s8 dbm value, which should be backward compatibility
when assign s8 to s32.

7fe9a3882b ieee802154: rework cca setting
The current cca setting handle is a driver specific call. We need to
introduce some 802.15.4 specific layer and mapping 802.15.4 cca modes to
driver specific ones inside the 802.15.4 driver. This patch will add
such 802.15.4 layer and mapping the cca settings to driver specific ones.

538181a879 mac802154: add synchronization handling
This patch adds synchronization handling in start and stop driver ops
calls. This patch is mostly grab from mac80211 which was introduced by
commit ea77f12f2c ("mac80211: remove
tasklet enable/disable"). This is to be sure that we don't run into same
issues.

e363eca386 mac802154: move local started handling
This patch removes the current handling of started boolean. This is
actually dead code, because mac802154_netdev_register can't never be
called before ieee802154_register_hw. This means that local->started is
always be true when mac802154_netdev_register is called. Instead we
using this now like mac80211 to indicate that an instance of sdata is
running.

b6eea9ca35 mac802154: introduce driver-ops header
This patch introduce a driver-ops header file with function wrappers to
call the driver ops. These wrappers checking on right context
information and warn if optional driver ops are called when these aren't
implemented. This behaviour is like mac80211 driver-ops header file,
just without function tracing calls.
