Additionally we decided it was best to split up the patches in this changeset as much as possible to individually addressable changes. You may have seen a new patch appear as a result of this. Thanks, Kieran
This patchset builds on the work down by Thomas Pedersen to add further support for 802.11ah in cfg80211 and mac80211. The ultimate goal is to enable the successful starting of an AP on 802.11ah using 802.11ah terms by implementing the various features that are required by the AP. The features are split into their own commits, please see those patches for more details. The patchset has been tested on both real hardware (Morse Micro MM610x) and mac80211_hwsim, in AP and STA modes. Basic regression testing was performed on 802.11n with mac80211_hwsim by starting an AP and having a STA interface connect to it. 802.11ah features/support missing: Rate control integration Regulatory database updates (only US regulatory information exists) Optional 802.11ah (S1G) features such as RAW, TWT and AID grouping Changelog v3: [PATCH 01/12] Added prototype definition and description for ieee80211_channel_to_freq_khz. Fixed issue introduced in v1 where center_freq_khz in handle_channel_custom() was uninitialised. [PATCH 10/12] Fixed comment block style v2: [PATCH 01/12] Added validation to assignment of s1g_oper_class and class_idx. Changed align_to_end from u8 to bool. Added clarification of usage requirements for country code in s1g_oper_class struct. Changed cc field in s1g_oper_class struct from char * to cc[3]. Moved initialised structs and arrays and from reg_s1g.h to reg_s1g.c. Moved reg_s1g_get_oper_class from reg_s1g.h to reg_s1g.c reg_s1g_get_oper_class now defaults to NULL if no natching s1g_oper_class is found. [PATCH 04/12] NL80211_ATTR_SHORT_BEACON_PERIOD changed to NLA_U16. [PATCH 07/12] Implemented ieee80211_ie_build_s1g_cap function to build S1G capability IE in place. Mimicing behaviour of ieee80211_ie_build_ht_cap. [PATCH 08/12] Capatilisation of MCS in description of RATE_INFO_FLAGS_S1G_MCS. Re-ordered grouping of fields in rate_info struct to order by size. [PATCH 09/12] Capatilisation of MCS in field naming of NL80211_RATE_INFO_S1G_MSS. Reordering of info->bw cases in switch to numberical order.
