carl9170 firmware: per-vif tx sequence counter

mac80211 will properly assign sequence numbers to QoS-data frames
but cannot do so correctly for non-QoS-data and management frames
because beacons need them from that counter as well and mac80211
cannot guarantee proper sequencing.

carl9170 firmware: Wake-on-LAN support

With this feature enabled, the device will stay
active while the host goes into System Standby
[Suspend to RAM!].

Furthermore, it scans all incoming 802.11 data frames
for a MAGIC WOL pattern and - when found - propagates
the wake-up call to the USB Host.

Notes/Limitations:
* Your host has to support USB remote wake-up.
  [In some cases, /proc/acpi/wakeup has to be
   configured as well - see Google for more
   details]

* The MAC address is taken from the device EEPROM.
  [so, ifconfig dev hw ether overrides don't
   work (yet)]

* The magic pattern has to be within the first
  320 bytes of the data frame.

* The magic frames has to be send unencrypted.
  Therefore the WOL initiator has to support
  frame injection [not a problem for most
  mac80211-based drivers].

* The initatior need to be in range and on the
  same channel as well.

mac80211: Remove unused third address from mesh address extension header.

they are interpreted as Addresses 5 and 6 (Address 4 being the 4th
address in the 802.11 header).

The address extension used to hold up to 3 addresses instead of the current 2.

Also, note that the extra address that I'm removing was not being used, so this

carl9170 firmware: fix CAB MAC RESET regression

commit "carl9170 firmware: improve tx ampdu ba_end handling"

Since the wlan_trigger was missing, the flushed CAB frames

mac80211: Update mesh constants to approved IEEE ANA values

This patch updates IEEE802.11 mesh constants to be consistent with newly
approved values. It modifies some values, as well as adds many new constants
in preparation for updating mesh code to the current 802.11s drafts. ANA
numbers were taken from:
https://mentor.ieee.org/802.11/dcn/09/11-09-0031-12-0000-ana-database-assigned-number-authority.xls

A few notes are in order:
1. This will break backwards compatibility with existing Linux kernels as
over-the-air constants have changed.
2. Some old and obsolete constants have been retained for now as the mesh code
itself hasn't been updated yet to the new 802.11s draft. This was desired to
keep the existing mesh scheme working until it can be updated. Adding the
approved values is the first step in updating the mesh code.
3. Obsolete constants have been clearly marked.
4. All ANA approved 802.11s constants have been added.
