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.

Standardize the net core ratelimited logging functions.

Coalesce formats, align arguments.
Change a printk then vprintk sequence to use printf extension %pV.

mac80211: set HT channel before association

2012-04-10T18:54:07+00:00

Changing the channel type during operation is
confusing to some drivers and will be hard to
handle in multi-channel scenarios. Instead of
changing the channel, set it to the right HT
channel before authenticating/associating and
don't change it -- just update the 20/40 MHz
restrictions in rate control as needed when
changed by the AP.

This also fixes a problem that Paul missed in
his fix for the "regulatory makes us deaf"
issue -- when we couldn't use 40 MHz we still
associated saying we were using 40 MHz, which
could in similarly broken APs make us never
even connect successfully.

mac80211: Use appropriate TID for sending BAR, ADDBA and DELBA frames

2011-12-15T19:46:35+00:00

Currently BAR, ADDBA and DELBA frames are always sent using AC_VO. If
the TID for which a BA session is established is assigned to a different
queue BAR, ADDBA and DELBA frames can "overtake" frames of the according
BA session.

Hence, always put BA session related frames into the same queue as the
BA sessions data frames.

mac80211: Remove WARN_ON in apply-ht-override logic.

2011-12-06T21:07:07+00:00

AP interfaces routinely call this logic, so just silently
return when this happens instead of splatting the kernel
logs.

mac80211: Add HT operation modes for IBSS

2011-12-06T21:05:25+00:00

The HT mode is set by iw (previous patchsets).
The interface is set into the specified HT mode.
HT mode and capabilities are announced in beacons.

If we add a station that uses HT also, the fastest matching HT mode will
be used for transmission. That means if we are using HT40+ and we add a station
running on HT40-, we would transfer at HT20.

If we join an IBSS with HT40, but the secondary channel is not
available, we will fall back into HT20 as well.

Allow frame aggregation to start in IBSS mode.

mac80211: Support ht-cap over-rides.

2011-11-21T21:22:06+00:00

This implements ht-cap over-rides for mac80211 drivers.
HT may be disabled, making an /a/b/g/n station act like an
a/b/g station.  HT40 may be disabled forcing the station to
be HT20 even if the AP and local hardware support HT40.

MAX-AMSDU may be disabled.
AMPDU-Density may be increased.
AMPDU-Factor may be decreased.

This has been successfully tested with ath9k using patched
wpa_supplicant and iw.
