->ndo_do_ioctl() can be entered with the rtnl lock already held,
for example when sending a wext ioctl to a device (in which case
the rtnl lock is taken by wext_ioctl_dispatch()), but
mac802154_wpan_ioctl() currently unconditionally takes the rtnl
lock on entry, which can cause deadlocks.
To fix this, bail out of mac802154_wpan_ioctl() before taking the
rtnl lock if the ioctl cmd is not one of the cmds we implement.

This patch removes the mib lock. The new locking mechanism is to protect
the mib values with the rtnl lock. Note that this isn't always necessary
if we have an interface up the most mib values are readonly (e.g.
address settings). With this behaviour we can remove locking in
hotpath like frame parsing completely. It depends on context if we need
to hold the rtnl lock or not, this makes the callbacks of
ieee802154_mlme_ops unnecessary because these callbacks hols always the
locks.

This patch introduce a flag property for the wpan phy structure.
The current flag settings in ieee802154_hw are accessable in mac802154
layer only which is okay for flags which indicates MAC handling which
are done by phy. For real PHY layer settings like cca mode, transmit
power, cca energy detection level.
The difference between these flags are that the MAC handling flags are
only handled in mac802154/HardMac layer e.g. on an interface up. The phy
settings are direct netlink calls from nl802154 into the driver layer
and the nl802154 need to have a chance to check if the driver supports
this handling before sending to the next layer.
We also check now on PHY flags while dumping and setting pib attributes.
In comparing with MIB attributes the 802.15.4 gives us an default value
which we assume when a transceiver implement less functionality. In case
of MIB settings the nl802154 layer doesn't need to check on the
ieee802154_hw flags then.

inside of interface up instead doing it it directly inside of netlink
interface. The netlink call which can only be called when netif isn't
running sets only the necessary short_addr value in sdata. After an
interface up the address filter will be set with this value.

This patch moves the setting of hardware extended address filtering
inside of interface up instead doing it directly inside of netlink interface.
Also we don't need to set the sdata extended attribute in netlink. This
is already done by ndo_set_mac_address of net_device_ops.

This patch removes the wpan_phy callbacks for add and del an interface
on a phy. Instead we introduce deprecated cfg802154 callbacks for this.
Furthermore we introduce a new netlink interface nl802154 which use
different callbacks. The deprecated function is to have a backwards
compatibility with the current netlink interface.

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.

This patch introduce the cfg802154_registered_device struct. Like
cfg80211_registered_device in wireless this should contain similar
functionality for cfg802154. This patch should not change any behaviour.
We just adds cfg802154_registered_device as container for wpan_phy struct.

This patch adds basic support for monitor mode. Also change the open
call that we set the transceiver mac setting on an interface up. Futher
patches will add a better handling while interface up an interface.

This patch replace the !netif_running(sdata->dev) instead we doing a

This patch change the actual crc handling while receive. Currently the
IEEE802154_HW_RX_OMIT_CKSUM flag is used to filter a frame with a bad crc.
This patch changes the behaviour of IEEE802154_HW_RX_OMIT_CKSUM to add a
crc while receiving for the monitor interface. After monitor receiving
we remove the crc for frame parsing. This affect the driver layer
because all drivers sets IEEE802154_HW_RX_OMIT_CKSUM and deliver without
checksum.

This patch splits the IEEE802154_HW_OMIT_CKSUM hardware flag into
IEEE802154_HW_TX_OMIT_CKSUM and IEEE802154_HW_RX_OMIT_CKSUM. This is
useful to deliver the received crc from the driver layer to the monitor
interface. At the moment we can't do that without change the xmit
handling.
The received checksum should be visible in monitor mode only.
