Statically compiled regulatory database
---------------------------------------
In most situations the userland solution using CRDA as described
above is the preferred solution. However in some cases a set of
rules built into the kernel itself may be desirable. To account
for this situation, a configuration option has been provided
(i.e. CONFIG_CFG80211_INTERNAL_REGDB). With this option enabled,
the wireless database information contained in net/wireless/db.txt is
used to generate a data structure encoded in net/wireless/regdb.c.
That option also enables code in net/wireless/reg.c which queries
the data in regdb.c as an alternative to using CRDA.
The file net/wireless/db.txt should be kept up-to-date with the db.txt
file available in the git repository here:
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-regdb.git
Again, most users in most situations should be using the CRDA package
provided with their distribution, and in most other situations users
should be building and using CRDA on their own rather than using
this option. If you are not absolutely sure that you should be using
CONFIG_CFG80211_INTERNAL_REGDB then _DO_NOT_USE_IT_.

* DOC: Spatial multiplexing power save

* and rationale, please refer to 802.11 (as amended by 802.11n-2009)
* "11.2.3 SM power save".
*
* The mac80211 implementation is capable of sending action frames
* to update the AP about the station's SMPS mode, and will instruct
* the driver to enter the specific mode. It will also announce the
* requested SMPS mode during the association handshake. Hardware
* support for this feature is required, and can be indicated by
* hardware flags.
*
* The default mode will be "automatic", which nl80211/cfg80211
* defines to be dynamic SMPS in (regular) powersave, and SMPS
* turned off otherwise.
*
* To support this feature, the driver must set the appropriate
* hardware support flags, and handle the SMPS flag to the config()
* operation. It will then with this mechanism be instructed to
* enter the requested SMPS mode while associated to an HT AP.
