ath9k: Adjust tbtt delta properly
In a GO/STA setup, when we switch to the STA context,
the channel context timer is scheduled with a period of
half the beacon interval. If a beacon is received in
this duration, the timer is adjusted to accommodate
TSF sync done by the HW.
But, if the actual channel switch is delayed for some
reason, we end up rearming the timer every time a new
beacon is received. Avoid this by doing the adjustment
only once.

ieee802154: || vs && in ieee802154_is_valid_extended_addr()
The ieee802154_is_valid_extended_addr() always returns true because
there is a typo. The || should be &&. Neither 0x0000000000000000ULL
nor 0xffffffffffffffffULL are valid addresses.

6lowpan: fix udp header compression when using raw sockets
If you use RAW sockets the transport header offset is not set by the
ipv6 stack so when we get to the udp header compression it does not
compress the right part of the packet.
This patch adds a check for this scenario and sets the transport
header offset.

mac80211: increase U-APSD max service period length
Deliver up to 128 frames during service period instead of 8 if
unlimited is specified by the client during association.
8 was just an arbitrary value; so is 128 since unlimited can
be any number.
However for large traffic bursts, increasing this value looks
reasonable. Also, it seems that a few certification tests
expect more frames to be delivered during SP.

mac80211: handle RIC data element in reassociation request
When the RIC data element (RDE) is included in the IEs coming
from userspace for an association request, its handling is
currently broken as any IEs that are contained within it would
be split off from it and inserted again after all the IEs that
mac80211 generates (e.g. HT, VHT.)
To fix this, treat the RIC element specially, and stop after
it only when we find something that doesn't actually belong to
it. This assumes userspace is actually correctly building it,
directly after the fast BSS transition IE and before all the
others like extended capabilities.
This leaves as a potential problem the case where userspace is
building the following IEs:
In this case, we'd erroneously consider all three IEs to be
part of the RIC data together, and not split them between the
two vendor IEs. Unfortunately, it isn't easily possible to
distinguish vendor IEs, so this isn't easy to fix. Luckily,
this case is rare as normally wpa_supplicant will include an
extended capabilities IE in the IEs, and that certainly will
break the two vendor IEs apart correctly.

This patch adds new iface type (NL80211_IFTYPE_OCB) representing
the OCB (Outside the Context of a BSS) mode.
When establishing a connection to the network a cfg80211_join_ocb
function is called (particular nl80211_command is added as well).
A mandatory parameters during the ocb_join operation are 'center
frequency' and 'channel width (5/10 MHz)'.
Changes done in mac80211 are minimal possible required to avoid
many warnings (warning: enumeration value 'NL80211_IFTYPE_OCB'
not handled in switch) during compilation. Full functionality
(where needed) is added in the following patch.

Firmware was crashing when we were trying to warm reset it
after suspend. This was due to the fact that target registeres
can be accessed only if the hardware is awaken.
This patch makes sure to awake the device also on the hif up,
not only in case of probe call.

Existing implementation of reset_resume handler just calls
ath6kl_usb_remove() that deallocates all resources.
It can lead to double free, etc. on disconnect.
The patch removes reset_resume handler,
so usb core could conservatively reset the driver.

netdevice: add ieee802154_ptr to net_device
This patch adds an ieee802154_ptr to the net_device structure.
Furthermore the 802.15.4 subsystem will introduce a nl802154 framework
which is similar like the nl80211 framework and a wpan_dev structure.
The wpan_dev structure will hold additional net_device attributes like
address options which are 802.15.4 specific. In the upcoming nl802154
implementation we will introduce a NL802154_FLAG_NEED_WPAN_DEV like
NL80211_FLAG_NEED_WDEV. For this flag an ieee802154_ptr in net_device is
needed. Additional we can access the wpan_dev attributes in upper layers
like IEEE 802.15.4 6LoWPAN easily. Current solution is a complicated
callback interface and getting these values over subif data structure
in mac802154.
