800aa9cd3d LinuxKPI: 80211 (+net80211): update and cleanup headers
Fix types for various struct fields (initially added as int).

Move structs and inline functions logically together, e.g., for wowlan.
Add more skeleton functions and #defines needed for iwlwifi d3.c
in the future.

Add struct ieee80211_vht_cap (without "_ie") to net80211 and remove
duplicate definitions in LinuxKPI headers now using net80211 structs.
For now leave ieee80211_ie_vhtcap in net80211.  I am not sure yet if we
actually need it as such.  That'll be cleaned up with more VHT updates
in net80211 in the future.

No functional changes in currently compiled code intended.

Try to implement ieee80211_action_contains_tpc() as I ran into it with
an older iwlwifi chipset.  This depends on c994352a88.

c9b7e9df18 net80211 / drivers: rename to IEEE80211_FC0_SUBTYPE_QOS_DATA
Going through the Frame (Sub)types the "QOS Data" being called "QOS"
scheme leads to a naming conflict for QOS_CFPOLL and QOS_CFACKPOLL
(if added).   Rename QOS* to QOS_DATA* to avoid the conflict and

04e7bb08a5 net80211: update for (more) VHT160 support
Implement two macros IEEE80211_VHTCAP_SUPP_CHAN_WIDTH_IS_160MHZ()
and its 80+80 counter part to check in vhtcaps for appropriate
levels of support and use the macros throughout the code.

Add vht160_chan_ranges/is_vht160_valid_freq and handle analogue
to vht80 in various parts of the code.

Add ieee80211_add_channel_cbw() which also takes the CBW flag
fields and make the former ieee80211_add_channel() a wrapper to it.
With the CBW flags we can add HT/VHT channels passing them to
getflags() for the 2/5ghz functions.

In ifconfig(8) add the regdomain_addchans() support for VHT160
and VHT80P80.

With this (+ regdoain.xml updates) VHT160 channels can be
configured, listed, and pass regdomain where appropriate.

fe267a5590 sys: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

c3ebe01919 Do not check sequence number for QoS Null frames; set it for generated QoS Null
frames to 0

From IEEE Std. 802.11-2012, 8.3.2.1 "Data frame format", p. 415 (513):
"The Sequence Control field for QoS (+)Null frames is ignored by the receiver
upon reception."

At this moment, any <mode>_input() function interprets them as regular QoS data
frames with TID = 0. As a result, stations, that use another TX sequence for
QoS Null frames (e.g. wpi(4), where (QoS) Null frames are generated by the
firmware), may experience significant packet loss with any other NIC in hostap
mode.

Tested:

* wpi(4) (author)
* iwn(4) - Intel 5100, STA mode (me)

59aa14a91d Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.
