grabbed from nl80211 framework.

This patch adds the new userspace header for nl802154. We don't place

next time.

This patch adds a wpan_dev_list list into cfg802154_registered_device
struct. Also adding new wpan_dev into this list while
cfg802154_netdev_notifier_call. This behaviour is mostly grab from
wireless core.c implementation and is needed for preparing nl802154
framework.

This patch adds an iftype argument to the wpan_dev. This is needed to

This patch removes the mac_params from subif data struct. Instead we
manipulate the wpan attributes directly.

This patch moves all mac pib attributes into the wpan_dev struct.
Furthermore we can easier access these attributes over the netdev
802154_ptr pointer. Currently this is only possible over a complicated
callback structure in mac802154 because subif data structure is
accessable inside mac802154 only.

Currently we ensure that the skb is freed on every error path in IPHC
decompression which makes it easy to introduce skb leaks. By centralising
the skb_free into the receive function it makes future decompression routines
easier to maintain. It does come at the expense of ensuring that the skb
passed into the decompression routine must not be copied.

If role switch was rejected by the controller and HCI Event: Command Status
returned with status "Command Disallowed" (0x0C) the flag
HCI_CONN_RSWITCH_PEND remains set. No further role switches are
possible as this flag prevents us from sending any new HCI Switch Role
requests and the only way to clear it is to receive a valid
HCI Event Switch Role.
This patch clears the flag if command was rejected.

This patch removes the af_ieee802154 defines and use the
IEEE802154_EXTENDED_ADDR_LEN. We should do this everywhere in the
802.15.4 subsystem because af_ieee802154 should be normally an uapi
header.

This patch adds a force setting of slotted operation bit. The atben
chips sometimes set these bit. The reason is unknown. Nevertheless we
don't support slotted operation so we set this bit now force while
probing.

This patch adding support for a perm extended address. This is useful
when a device supports an eeprom with a programmed static extended address.
If a device doesn't support such eeprom or serial registers then the
driver should generate a random extended address.
