mac80211: disable VHT for TDLS

2014-07-21T10:14:04Z

TDLS VHT support requires some more information elements during setup. While these are not there, mask out the peer's VHT capabilities so that VHT rates are not mistakenly used. Signed-off-by: Arik Nemtsov Reviewed-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

mac80211: allow VHT with peers not capable of 40MHz

2014-05-09T07:56:53Z

There are two (related) issues with this. One case, reported by Michal, is related to hostap: it unsets the 20/40 capability bit for stations that associate when it's in 20 MHz mode. The other case, reported by Eyal, is that some APs like Netgear R6300v2 and probably others based on the BCM4360 chipset can be configured for doing VHT at 20Mhz. In this case the beacon has a VHT IE but the HT cap indicates transmitter only support 20Mhz. In both of these cases, we currently avoid VHT and use only HT this means we can't use the highest rates (MCS8), so fixing this leads to throughput improvements.

mac80211: update opmode when adding new station

2014-02-05T13:03:23Z

Update the operating mode field is needed when an association request contains the operating mode notification element and it's not just changed later on the fly. Signed-off-by: Marek Kwaczynski [clarify commit log, comments & fix whitespace] Signed-off-by: Johannes Berg

mac80211: enable easier manipulation of VHT beamforming caps

2013-11-25T19:52:01Z

Introduce shift and mask defines for beamformee STS cap and number of sounding dimensions cap as these can take any 3 bit value. While at it also cleanup an unrequired parenthesis. Signed-off-by: Eyal Shapira Reviewed-by: Johannes Berg Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

ieee80211: fix vht cap definitions

2013-10-01T10:17:08Z

VHT_CAP_BEAMFORMER_ANTENNAS cap is actually defined in the draft as VHT_CAP_BEAMFORMEE_STS_MAX, and its size is 3 bits long. VHT_CAP_SOUNDING_DIMENSIONS is also 3 bits long. Fix the definitions and change the cap masking accordingly. Signed-off-by: Eliad Peller Signed-off-by: Johannes Berg

mac80211: restrict peer's VHT capabilities to own

2013-03-06T15:36:03Z

Implement restricting peer VHT capabilities to the device's own capabilities. This is useful when a single driver supports more than one device and the devices have different capabilities (often they will differ in the number of spatial streams), but in particular is also necessary for VHT capability overrides to work correctly -- otherwise it'd be possible to e.g. advertise, due to overrides, that TX-STBC is not supported, but then still use it to TX to the AP because it supports RX-STBC.

mac80211: handle operating mode notif in beacon/assoc response

2013-02-15T08:41:34Z

In beacons and association response frames an AP may include an operating mode notification element to advertise changes in the number of spatial streams it can receive. Handle this using the existing function that handles the action frame, but only handle NSS changes, not bandwidth changes which aren't allowed here. Signed-off-by: Johannes Berg
