Allow user to override STBC configuration for Rx and Tx spatial streams. In practice RX/TX STBC settings can be modified using appropriate options in wpa_supplicant configuration file: tx_stbc=-1..1 rx_stbc=-1..3 This functionality has been added to wpa_supplicant in commit cdeea70f59d0. In FullMAC case these STBC options are passed to drivers by cfg80211 connect callback in fields of cfg80211_connect_params structure. However for mac80211 drivers, e.g. for mac80211_hwsim, overrides for STBC settings are ignored. The reason why RX/TX STBC capabilities are not modified for mac80211 drivers is as follows. All drivers need to specify supported HT/VHT overrides explicitly: see ht_capa_mod_mask and vht_capa_mod_mask fields of wiphy structure. Only supported overrides will be passed to drivers by cfg80211_connect and cfg80211_mlme_assoc operations: see bitwise 'AND' performed by cfg80211_oper_and_ht_capa and cfg80211_oper_and_vht_capa. This commit adds RX/TX STBC HT capabilities to mac80211_ht_capa_mod_mask, allowing their modifications, as well as applies requested STBC modifications in function ieee80211_apply_htcap_overrides.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
