This patch reworks the wpan_phy index incrementation. It's now similar
like wireless wiphy index incrementation. We move the wpan_phy index
attribute inside of cfg802154_registered_device and use atomic
operations instead locking mechanism via wpan_phy_mutex.

The include/net/nl802154.h file contains a lot of prototypes which are
not used inside of ieee802154 subsystem. This patch removes this file
and make the only one used prototype "ieee802154_nl_start_confirm" as
static declaration in ieee802154/nl-mac.c

This patch moves and rename the mac802154_del_iface function into
iface.c and rename the function to ieee802154_if_remove which is a similar
naming convention like mac80211.

This patch moves and renames the mac802154_add_iface and
mac802154_netdev_register functions into iface.c. The function
mac802154_add_iface is renamed to ieee802154_if_add which is a similar naming
convention like mac80211.

This patch moves the dev_hold call inside of nl-phy ieee802154_add_iface
function. The ieee802154_add_iface is the only one function which use the
ieee802154_if_add function and contains the corresponding dev_put call.

This patch meld mac802154_netdev_register into ieee802154_if_add
function. Also we have now only one alloc_netdev call with one interface
setup routine "ieee802154_if_setup" instead two different one for each
interface type. This patch checks via runtime the interface type and do
different handling now. Additional we add the wpan_dev struct in
ieee802154_sub_if_data and set the new ieee802154_ptr while netdev
registration. This behaviour is very similar the mac80211 netdev
registration functionality.

This patch removes the get_phy callback from mlme ops structure. Instead
we doing a dereference via ieee802154_ptr dev pointer. For backwards
compatibility we need to run get_device after dereference wpan_phy via
ieee802154_ptr.

This patch adds a default interface registration for a wpan interface
type. Currently the 802.15.4 subsystem need to call userspace tools to
add an interface. This patch is like mac80211 handling for registration
a station interface type by default.

This patch adds an ieee802154_vif similar like the ieee80211_vif which
holds the interface type and maybe further more attributes like the
ieee80211_vif structure.

First of all why do we need this functionality. Extended address will be configured by the
user by using iz ..?

If those 8 bytes not a valid addr, then you are toggling last bit, Why..?

We need such function for the perm extended address. The extended
address is some unique number. It's an EUI-64 address this should be
unique and hardware companies can allocate OUI. The EUI-64 is some
combine OUI and device identifier. The perm address can be used that the
driver ask the transceiver for serial id or eeprom and set the unique
extended address. Also the IEEE 802.15.4-2011 standard describes the
default value for an extended address as "Implementation specific". The
perm address is now the "Implementation specific" behaviour.
The iz tool sets no perm address, it's just another address than the
perm address if you want that. This is also only an optional parameter
if this is zero the perm address will be used.
Also we have now a default registration for a wpan interface, this will
always use the perm address which is a random extended address now.
We need this function like a random ethernet address. If a transceiver
doesn't support some serial id or eeprom where we can generate an EUI-64
address, then we will generate a valid random extended address.
In case of short address the default value is 0xffff. Short address will
be assign from coordinators... but we are far away from that to support
such behaviour.

EUI-64 values 0xff..ff and 0x00..00 are owned by IEEE [0]. The function
"ieee802154_is_valid_extended_addr" will return "false" when we hit such
address. Now we flip some bit to get out of an invalid IEEE address...
btw. the 0xff..ff will be used as mapping for short broadcast address
and 0x00..00 should be the default monitor interface address. (This
should be not be changed at runtime, I have patches for this but there
is alot of other things where I have patches for it).

This patch adds a new function to convert a le64 to a be64. This is
useful to translate an extended address to a netdev dev_addr.

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.

You are getting this extended address here and configuring at the time
of iface add.
This change should be there for other drivers ( CC2520 & MRF24J40 ) also ..?

yes, but please refer before if these transceivers supports some eeprom
or serial id where the extended addr could be generated from.
Otherwise we need to generate a random one. This value can also get from
device tree or extended addr, but we are far away to support such
behaviour. If somebody wants to implement this, please send patches to
me and device tree ml.

what's about this, to having a zero address perm_extended_addr address
is defintly a bug in your driver.
My respone here was more a (this is not really c, but mention what I
meant here):
switch (CC2520_supports)
case EEPROM_FOR_EUI64:
perm_extended_addr = readout_eeprom;
break;
case SERIAL_ID_REGISTERS_FOR_EUI64:
perm_extended_addr = readout_registers;
break;
default:
perm_extended_addr = generate_random_one;
}
So if you don't have case 1 and 2, then generate a random one.
Also please check for reset values for phy settings like
current_channel, current_page...
Maybe wait some time when cca handling patches are in then you can
changes also the cca mode to the default value after reset.

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 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.
