* wireless: Set NL80211_EXT_FEATURE_CQM_RSSI_LIST in multiple driversAndrew Zaborowski2017-03-061-0/+2
| | | | | | | | | | | | | | Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature wholesale in all mac80211-based drivers that do not set the IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and will detect when the thresholds set by ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few) drivers need code to enable the firmware to monitor the thresholds. This is mostly only compile-tested.

* cfg80211: remove enum ieee80211_bandJohannes Berg2016-04-121-3/+3
| | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: pass block ack session timeout to to driverSara Sharon2016-01-141-3/+5
| | | | | | | | | | | | Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.

* mac80211: convert HW flags to unsigned long bitmapJohannes Berg2015-06-101-10/+10
| | | | | | | | | | | | | | | As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

* mac80211: remove support for IFF_PROMISCJohannes Berg2015-04-241-4/+3
| | | | | | | | | | | This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Set the flag in all drivers that have been tested with CCK rates.

* carl9170: add support for the new rate control APIChristian Lamparter2013-06-131-0/+3
| | | | | | | | | | | | | | | | | With the new rate control API, the driver can now apply the tx rate to outgoing frames just before they are uploaded to the device. This is important because the rate control can now react to fading or improving links a bit sooner. Also, the driver no longer needs to sort the outgoing frames for sample attempts (which affected the size of A-MPDUs and the throughput of the link). For aggregated data frames, the driver (and rate control) needs only to calculate and apply a single set of tx rates to every subframe of the whole aggregate.

* | carl9170: remove fast channel change featureChristian Lamparter2013-03-271-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | Marco Fonseca reported a issue with his carl9170 device: "I'm seeing a problem with the carl driver. If I change channels repeatedly on the 2.4ghz band, monitoring (e.g. tcpdump) will eventually halt. I've seen this on various versions of the carl driver/firmware (both from 1.9.4 to 1.9.7)" <http://marc.info/?l=linux-wireless&m=136381302428113> The culprit was identified as "fast channel change feature" which according to Adrian Chadd is: "... notoriously unreliable and really only fully debugged on some very later chips." <http://marc.info/?l=linux-wireless&m=136416984531380> Therefore, this patch removes the fast channel change feature.

* mac80211: pass queue bitmap to flush operationJohannes Berg2013-03-181-1/+1
| | | | | | | | | | There are a number of situations in which mac80211 only really needs to flush queues for one virtual interface, and in fact during this frames might be transmitted on other virtual interfaces.

* mac80211: inform the driver about update of dtim_periodEmmanuel Grumbach2013-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Currently, when the driver requires the DTIM period, mac80211 will wait to hear a beacon before association. This behavior is suboptimal since some drivers may be able to deal with knowing the DTIM period after the association, if they get it at all. To address this, notify the drivers with bss_info_changed with the new BSS_CHANGED_DTIM_PERIOD flag when the DTIM becomes known. This might be when changing to associated, or later when the entire association was done with only probe response information. Rename the hardware flag for the current behaviour to IEEE80211_HW_NEED_DTIM_BEFORE_ASSOC to more accurately reflect its behaviour. IEEE80211_HW_NEED_DTIM_PERIOD is no longer accurate as all drivers get the DTIM period now, just not before association.

| | | | | | | | | | | | | | | | | | | | | | | | | | | When TX aggregation is stopped, there are a few different cases: - connection with the peer was dropped - session stop was requested locally - session stop was requested by the peer - connection was dropped while a session is stopping The behaviour in these cases should be different, if the connection is dropped then the driver should drop all frames, otherwise the frames may continue to be transmitted, aggregated in the case of a locally requested session stop or unaggregated in the case of the peer requesting session stop. Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more. In the case of connection drop, the stop callback the driver is otherwise supposed to call is no longer required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* carl9170: fix allmulticast modeNicolas Cavallari2011-05-051-1/+1
| | | | | | | | | | | | | | | | | | Currently, the driver only disable multicast filtering when the FIF_ALLMULTI driver flag has been just set (ie, if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else it will reenable multicast filtering. But next time, this condition will be false and multicast filtering will be reenabled, even through FIF_ALLMULTI is still set. This mean that allmulticast only works for less than two minutes in ad-hoc mode. This patch fixes that to disable multicast filtering as long as FIF_ALLMULTI is set.
