mac80211: stop modifying HT SMPS capability

2013-02-15T08:41:41+00:00

Instead of modifying the HT SMPS capability field
for stations, track the SMPS mode explicitly in a
new field in the station struct and use it in the
drivers that care about it. This simplifies the
code using it.

mac80211: constify IE parsing

2013-02-15T08:41:39+00:00

Make all the parsed IE pointers const, and propagate
the change to all the users etc.

mac80211: handle VHT operating mode notification

2013-02-15T08:41:32+00:00

Handle the operating mode notification action frame.
When the supported streams or the bandwidth change
let the driver and rate control algorithm know.

mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40

2013-02-15T08:41:30+00:00

For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

mac80211: allow driver to be stateless wrt. SMSP requests

2013-02-12T09:10:28+00:00

Bail out if no update is made to the SMPS state. This
allows the driver to avoid duplicating the state.

mac80211: unset peer's HT 40 MHz support if not usable

2013-01-03T12:01:45+00:00

When an interface is configured to a 20 MHz channel
and the device as well as the peer are 40 MHz capable
the HT capabilities of the peer are not restricted to
20 MHz, even though they're supposed to be restricted
to the currently possible capabilities.

Unset the 40 MHz HT capability bits in this case.

mac80211: split aggregation stop by reason

2013-01-03T12:01:41+00:00

The initiator/tx doesn't really identify why an
aggregation session is stopped, give a reason
for stopping that more clearly identifies what's
going on. This will help tell the driver clearly
what is expected of it.

mac80211: Allow disabling SGI-20

2013-01-03T12:01:14+00:00

This allows user-space (wpa_supplicant) to disable
short guard interval (SGI) for 20Mhz.  The SGI-40
disable option is already handled.

mac80211: introduce IEEE80211_NUM_TIDS and use it

2012-11-19T14:44:00+00:00

Introduce IEEE80211_NUM_TIDS in the generic 802.11
header file and use it in place of STA_TID_NUM and
NUM_RX_DATA_QUEUES which are both really the number
of TIDs.

mac80211: clean up debugging

2012-06-24T09:32:29+00:00

There are a few things that make the logging and
debugging in mac80211 less useful than it should
be right now:
 * a lot of messages should be pr_info, not pr_debug
 * wholesale use of pr_debug makes it require *both*
   Kconfig and dynamic configuration
 * there are still a lot of ifdefs
 * the style is very inconsistent, sometimes the
   sdata->name is printed in front

Clean up everything, introducing new macros and
separating out the station MLME debugging into
a new Kconfig symbol.
