This patch removes the kmalloc allocation for workqueue data. This patch
replaces the kmalloc and uses the control block of skb. The control block
has enough space and isn't use by any other layer in this case.

This patch replace the mac802154_to_priv macro with a static inline
function named hw_to_local. This brings a similar naming convention like

Like wireless this structure should named ieee802154_sub_if_data and not
mac802154_sub_if_data. This patch renames the struct and variables to
sdata instead priv sometimes.

This patch rename the mac802154_priv to ieee802154_local. The
mac802154_priv structure is like ieee80211_local and so we name it
ieee802154_local.

The wpan-phy header contains the wpan_phy struct information. Later this
header will be have similar function like cfg80211 header. The cfg80211
header contains the wiphy struct which is identically the wpan_phy
struct inside 802.15.4 subsystem.

This patch moves the mac802154.h internal header to ieee802154_i.h like
the wireless stack ieee80211_i.h file. This avoids confusing with the
not internal header include/net/mac802154.h header. Additional we get
the same naming conversion like mac80211 for this file.

Two sections checked whether the current channel != the new channel
without ever setting the current channel variables.
1. net/mac802154/tx.c: Prevent set_channel() from getting called every
time a packet is sent.
2. net/mac802154/mib.c: Lock (pib_lock) accesses to current_channel and
current_page and make sure they are updated when the channel has been
changed.

Use netif_stop_queue() and netif_wake_queue() to control the flow of
packets to mac802154 devices. Since many IEEE 802.15.4 devices have no
output buffer, and since the mac802154 xmit() function is designed to
block, netif_stop_queue() is called after each packet.

When ops->xmit() fails, drop the packet. Devices which support hardware
ack and retry (which include all devices currently supported by mainline),
will automatically retry sending the packet (in the hardware) up to 3
times, per the 802.15.4 spec. There is no need, and it is incorrect to
try to do it in mac802154.

Conflicts:

The qmi_wwan merge was trivial.
The caif_hsi.c, on the other hand, was not. It's a conflict between
1c385f1fdf ("caif-hsi: Replace platform
device with ops structure.") in the net-next tree and commit
39abbaef19 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.
I did my best with that one and will ask Sjur to check it out.
