* mac80211: allow drivers to provide most station statisticsJohannes Berg2015-01-081-15/+15
| | | | | | | | | | | | | | | | | | | In many cases, drivers can filter things like beacons that will skew statistics reported by mac80211. To get correct statistics in these cases, call drivers to obtain statistics and let them override all values, filling values from mac80211 if the driver didn't provide them. Not all of them make sense for the driver to fill, so some are still always done by mac80211. Note that this doesn't currently allow a driver to say "I know this value is wrong, don't report it at all", or to sum it up with a mac80211 value (as could be useful for "dropped misc"), that can be added if it turns out to be needed. This also gets rid of the get_rssi() method as is can now be implemented using sta_statistics(). Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Verify low-level driver support for the new ops when using the relevant wiphy feature bit. Also verify the peer supports channel switching before passing the command down.

* mac80211: 802.11p OCB mode supportRostislav Lisovy2014-11-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | This patch adds 802.11p OCB (Outside the Context of a BSS) mode support. When communicating in OCB mode a mandatory wildcard BSSID (48 '1' bits) is used. The EDCA parameters handling function was changed to support 802.11p specific values. The insertion of a newly discovered STAs is done in the similar way as in the IBSS mode -- through the deferred insertion. The OCB mode uses a periodic 'housekeeping task' for expiration of disconnected STAs (in the similar manner as in the MESH mode). New Kconfig option for verbose OCB debugging outputs is added.

| | | | | | | | | | | | | | | | | Split sched scan IEs to band specific and not band specific blocks. Common IEs blocks may be sent to the FW once per command, instead of per band. This allows optimization of size of the command, which may be required by some drivers (eg. iwlmvm with newer firmware version).

* mac80211: add a single-transaction driver op to switch contextsLuciano Coelho2014-05-261-0/+53
| | | | | | | | | | | | | | | | In some cases, when the driver is already using all the channel contexts it can handle at once, we have to do an in-place switch (ie. we cannot afford using an extra context temporarily for the transaction). But some drivers may not support switching the channel context assigned to a vif on the fly (ie. without unassigning and assigning it) while others may only work if the context is changed on the fly, without unassigning it first. To allow these different scenarios, add a new driver operation that let's the driver decide how to handle an in-place switch.

The API returns a value expressed in Kbps. Also, add the new get_expected_throughput() member to the rate_control_ops structure in order to be able to query the RC algorithm (this patch provides an implementation of this API for both minstrel and minstrel_ht).

* mac80211: add pre-RCU-sync sta removal driver operationJohannes Berg2013-12-161-0/+16
| | | | | | | | | | | | | | | | | | | | | | | Currently, mac80211 allows drivers to keep RCU-protected station references that are cleared when the station is removed from the driver and consequently needs to synchronize twice, once before removing the station from the driver (so it can guarantee that the station is no longer used in TX towards the driver) and once after the station is removed from the driver. Add a new pre-RCU-synchronisation station removal operation to the API to allow drivers to clear/invalidate their RCU-protected station pointers before the RCU synchronisation. This will allow removing the second synchronisation by changing the driver API so that the driver may no longer assume a valid RCU-protected pointer after sta_remove/sta_state returns. The alternative to this would be to synchronize_rcu() in all the drivers that currently rely on this behaviour (only iwlmvm) but that would defeat the purpose.

* mac80211: add supported rates change notification in IBSSAntonio Quartulli2012-08-201-0/+3
| | | | | | | | | | | | | | | | In IBSS it is possible that the supported rates set for a station changes over time (e.g. it gets first initialised as an empty set because of no available information about rates and updated later). In this case the driver has to be notified about the change in order to update its internal table accordingly (if needed). This behaviour is needed by all those drivers that handle rc internally but leave stations management to mac80211 Reported-by: Gui Iribarren <gui@altermundi.net> Signed-off-by: Antonio Quartulli <ordex@autistici.org> [Johannes - add docs, validate IBSS mode only, fix compilation] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
