cfg80211: remove channel_switch combination check

2014-06-25T16:06:20Z

Driver is now responsible for veryfing if the switch is possible. Since this is inherently tricky driver may decide to disconnect an interface later with cfg80211_stop_iface(). This doesn't mean driver can accept everything. It should do it's best to verify requests and reject them as soon as possible. Signed-off-by: Michal Kazior Signed-off-by: Johannes Berg

cfg80211: pass TDLS initiator in tdls_mgmt operations

2014-06-23T12:24:55Z

The TDLS initiator is set once during link setup. If determines the address ordering in the link identifier IE. Fix dependent drivers - mwifiex and mac80211. Signed-off-by: Arik Nemtsov Signed-off-by: Johannes Berg

cfg80211: make ethtool the driver's responsibility

2014-06-23T09:05:33Z

Currently, cfg80211 tries to implement ethtool, but that doesn't really scale well, with all the different operations. Make the lower-level driver responsible for it, which currently only has an effect on mac80211. It will similarly not scale well at that level though, since mac80211 also has many drivers. To cleanly implement this in mac80211, introduce a new file and move some code to appropriate places. Signed-off-by: Johannes Berg

cfg80211: allow RSSI compensation

2014-05-22T07:58:49Z

Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.

cfg80211: implement cfg80211_get_station cfg80211 API

2014-05-21T07:15:17Z

Implement and export the new cfg80211_get_station() API. This utility can be used by other kernel modules to obtain detailed information about a given wireless station. It will be in particular useful to batman-adv which will implement a wireless rate based metric. Signed-off-by: Antonio Quartulli Signed-off-by: Johannes Berg

cfg80211: export expected throughput through get_station()

2014-05-20T13:13:32Z

Users may need information about the expected throughput towards a given peer. This value is supposed to consider the size overhead generated by the 802.11 header. This value is exported in kbps through the get_station() API by including it into the station_info object. Moreover, it is sent to user space when replying to the nl80211 GET_STATION command. This information will be useful to the batman-adv module which will use it for its new metric computation. Signed-off-by: Antonio Quartulli Signed-off-by: Johannes Berg

cfg80211: constify wowlan/coalesce mask/pattern pointers

2014-05-19T16:06:50Z

This requires changing the nl80211 parsing code a bit to use intermediate pointers for the allocation, but clarifies the API towards the drivers. Signed-off-by: Johannes Berg

cfg80211: constify more pointers in the cfg80211 API

2014-05-19T15:53:16Z

This also propagates through the drivers. The orinoco driver uses the cfg80211 API structs for internal bookkeeping, and so needs a (void *) cast that removes the const - but that's OK because it allocates those pointers. Signed-off-by: Johannes Berg

cfg80211: constify MAC addresses in cfg80211 ops

2014-05-19T15:34:42Z

This propagates through all the drivers and mac80211. Signed-off-by: Johannes Berg
