2013-03-25mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chanKarl Beldan
Drivers that don't use chanctxes cannot perform VHT association because they still use a "backward compatibility" pair of {ieee80211_channel, nl80211_channel_type} in ieee80211_conf and ieee80211_local.

2012-10-29carl9170: fix spurious transmissions in sniffer modeChristian Lamparter
Several people have complained about an unusual and undocumented feature of the AR9170 hardware: In siffer mode, the hardware generates spurious ACK frames for every received frame... even broadcasts. The reason for this malfunction is unknown: <http://marc.info/?l=linux-wireless&m=134517238506033> But there's a workaround: Instead of the special sniffer mode, the hardware will be put into station mode and all rx filters are disabled.

2012-09-24carl9170: connect to 11w protected networksChristian Lamparter
Previously, it was not possible to connect to networks which requires 11w to be supported by the stations. While the documentation hints that there's some hardware support for offloading MFP "decryption", this simple implementation relies on the mac80211 stack to do the actual crypto operations.

2012-08-06carl9170: Add support for NL80211_IFTYPE_MESH_POINT interfacesJavier Lopez
This patch contains following modifications: - Add mesh capabilities on fw.c to permit creation of mesh interfaces using this driver. - Modify carl9170_set_operating_mode, to use AP-style beaconing with mesh interfaces. - Allow beacon updates for NL80211_IFTYPE_MESH_POINT type in carl9170_handle_command_response. - Add NL80211_IFTYPE_MESH_POINT case on carl9170_op_add_interfaces to support mesh/ap/sta virtual interface combinations.

2010-11-15carl9170: configurable beacon ratesChristian Lamparter
Previously, the beacon rate was fixed to either: * 1Mb/s [2.4GHz band] * 6Mb/s [5GHz band] This limitation has been addressed and now the beacon rate is selected by ieee80211_tx_info's rate control info, almost like any ordinary data frame.
