This patch changes the default minimum value of frame_retries to 0 and
changes the frame_retries default value to 3 which is also 802.15.4
default.We don't use the frame_retries "-1" value as indicator for no-aret mode
anymore, instead we checking on the ack request bit inside the 802.15.4
frame control field. This allows a acknowledge handling per frame. This
checking is done by transceiver or inside xmit callback of driver layer.If a transceiver doesn't support ARET handling the transmit
functionality ignores ack frames then, which isn't well but should not
effect anything of current functionality.Reviewed-by: Stefan Schmidt

When transmitting a packet via a mac802154 driver that can sleep in
its transmit function, mac802154 defers the call to the driver's
transmit function to a per-device workqueue.However, mac802154 uses a single global work_struct for this, which
means that if you have more than one registered mac802154 interface
in the system, and you transmit on more than one of them at the same
time, you'll very easily cause memory corruption.This patch moves the deferred transmit processing state from global
variables to struct ieee802154_local, and this seems to fix the memory
corruption issue.Signed-off-by: Lennert Buytenhek

This patch adds support for phy supported handling for all other already
existing handling 802.15.4 functionality. We assume now a fully 802.15.4
complaint transceiver at phy allocation. If a transceiver can support
802.15.4 default values only, then the values should be overwirtten by
values the transceiver supports. If the transceiver doesn't set the
according hardware flags, we assume the 802.15.4 defaults now which
cannot be changed.Signed-off-by: Alexander Aring

This code is based on commit 6bab2e19c5ffd
("cfg80211: pass name_assign_type to rdev_add_virtual_intf()")This will expose in sysfs whether the ifname of a IEEE-802.15.4
device is set by userspace or generated by the kernel.
We are using two types of name_assign_types
o NET_NAME_ENUM: Default interface name provided by kernel
o NET_NAME_USER: Interface name provided by user.Signed-off-by: Varka Bhadram

This patch adds support for setting an extended address while
registration a new interface. If ieee802154_is_valid_extended_addr

is fallback. This is useful to make some default handling while for
example default registration of a wpan interface while phy registration.Signed-off-by: Alexander Aring

This parameter was grabbed from wireless implementation with the

This patch replace the depracted IEEE802154_DEV to the new introduced
NL802154_IFTYPE_NODE types. There is a backwards compatibility to have
the identical types for both enum definitions. Also remove some inlcude
issue with "linux/nl802154.h", because the export nl_policy inside this
header it was always necessary to have an include of "net/rtnetlink.h"
before. The reason for this is more complicated. Nevertheless we removed
this now, because "linux/nl802154.h" is the depracted netlink interface.Signed-off-by: Alexander Aring

This patch adds a new interframe spacing time handling into mac802154
layer. Interframe spacing time is a time period between each transmit.
This patch adds a high resolution timer into mac802154 and starts on
xmit complete with corresponding interframe spacing expire time if
ifs_handling is true. We make it variable because it depends if
interframe spacing time is handled by transceiver or mac802154. At the
timer complete function we wake the netdev queue again. This avoids
new frame transmit in range of interframe spacing time.For synced driver we add no handling of interframe spacing time. This
is currently a lack of support in all synced xmit drivers. I suppose
it's working because the latency of workqueue which is needed to call
spi_sync.Signed-off-by: Alexander Aring

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

Tasklets have much less overhead than workqueues. This patch also
removes the heap allocation for the worker on receiving path.
Like mac80211 we should prefer use a tasklet here instead a workqueue to
getting fast out of interrupt context when ieee802154_rx_irqsafe is
called by driver. Like wireless inside the tasklet context we should
call netif_receive_skb instead netif_rx_ni anymore.Signed-off-by: Alexander Aring
