============================= mac80211 subsystem (advanced) ============================= Information contained within this part of the book is of interest only for advanced interaction of mac80211 with drivers to exploit more hardware capabilities and improve performance. LED support =========== Mac80211 supports various ways of blinking LEDs. Wherever possible, device LEDs should be exposed as LED class devices and hooked up to the appropriate trigger, which will then be triggered appropriately by mac80211. .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_tx_led_name .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_rx_led_name .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_assoc_led_name .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_radio_led_name .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_tpt_blink .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_tpt_led_trigger_flags .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_create_tpt_led_trigger Hardware crypto acceleration ============================ .. kernel-doc:: include/net/mac80211.h :doc: Hardware crypto acceleration .. kernel-doc:: include/net/mac80211.h :functions: set_key_cmd .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_key_conf .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_key_flags .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_tkip_p1k .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_tkip_p1k_iv .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_tkip_p2k Powersave support ================= .. kernel-doc:: include/net/mac80211.h :doc: Powersave support Beacon filter support ===================== .. kernel-doc:: include/net/mac80211.h :doc: Beacon filter support .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_beacon_loss Multiple queues and QoS support =============================== TBD .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_tx_queue_params Access point mode support ========================= TBD Some parts of the if_conf should be discussed here instead Insert notes about VLAN interfaces with hw crypto here or in the hw crypto chapter. support for powersaving clients ------------------------------- .. kernel-doc:: include/net/mac80211.h :doc: AP support for powersaving clients .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_get_buffered_bc .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_beacon_get .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_sta_eosp .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_frame_release_type .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_sta_ps_transition .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_sta_ps_transition_ni .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_sta_set_buffered .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_sta_block_awake Supporting multiple virtual interfaces ====================================== TBD Note: WDS with identical MAC address should almost always be OK Insert notes about having multiple virtual interfaces with different MAC addresses here, note which configurations are supported by mac80211, add notes about supporting hw crypto with it. .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_iterate_active_interfaces .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_iterate_active_interfaces_atomic Station handling ================ TODO .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_sta .. kernel-doc:: include/net/mac80211.h :functions: sta_notify_cmd .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_find_sta .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_find_sta_by_ifaddr Hardware scan offload ===================== TBD .. kernel-doc:: include/net/mac80211.h :functions: ieee80211_scan_completed Aggregation =========== TX A-MPDU aggregation --------------------- .. kernel-doc:: net/mac80211/agg-tx.c :doc: TX A-MPDU aggregation ..
