In some chapters, +advanced usage is noted, those may be skipped if this isn't needed. + +This part of the book only covers station and monitor mode +functionality, additional information required to implement the other +modes is covered in the second part of the book. + +Basic hardware handling +======================= + +TBD + +This chapter shall contain information on getting a hw struct allocated +and registered with mac80211. + +Since it is required to allocate rates/modes before registering a hw +struct, this chapter shall also contain information on setting up the +rate/mode structs. + +Additionally, some discussion about the callbacks and the general +programming model should be in here, including the definition of +ieee80211_ops which will be referred to a lot. + +Finally, a discussion of hardware capabilities should be done with +references to other parts of the book. + +.. kernel-doc:: include/net/mac80211.h + :functions: + ieee80211_hw + ieee80211_hw_flags + SET_IEEE80211_DEV + SET_IEEE80211_PERM_ADDR + ieee80211_ops + ieee80211_alloc_hw + ieee80211_register_hw + ieee80211_unregister_hw + ieee80211_free_hw + +PHY configuration +================= + +TBD + +This chapter should describe PHY handling including start/stop callbacks +and the various structures used. + +.. kernel-doc:: include/net/mac80211.h + :functions: + ieee80211_conf + ieee80211_conf_flags + +Virtual interfaces +================== + +TBD + +This chapter should describe virtual interface basics that are relevant +to the driver (VLANs, MGMT etc are not.) It should explain the use of +the add_iface/remove_iface callbacks as well as the interface +configuration callbacks. + +Things related to AP mode should be discussed there. + +Things related to supporting multiple interfaces should be in the +appropriate chapter, a BIG FAT note should be here about this though and +the recommendation to allow only a single interface in STA mode at +first! + +.. kernel-doc:: include/net/mac80211.h + :functions: ieee80211_vif + +Receive and transmit processing +=============================== + +what should be here +------------------- + +TBD + +This should describe the receive and transmit paths in mac80211/the +drivers as well as transmit status handling. + +Frame format +------------ + +.. kernel-doc:: include/net/mac80211.h + :doc: Frame format + +Packet alignment +---------------- + +.. kernel-doc:: net/mac80211/rx.c + :doc: Packet alignment + +Calling into mac80211 from interrupts +------------------------------------- + +.. kernel-doc:: include/net/mac80211.h + :doc: Calling mac80211 from interrupts + +functions/definitions +--------------------- + +.. kernel-doc:: include/net/mac80211.h + :functions: + ieee80211_rx_status + mac80211_rx_encoding_flags + mac80211_rx_flags + mac80211_tx_info_flags + mac80211_tx_control_flags + mac80211_rate_control_flags + ieee80211_tx_rate + ieee80211_tx_info + ieee80211_tx_info_clear_status + ieee80211_rx + ieee80211_rx_ni + ieee80211_rx_irqsafe + ieee80211_tx_status + ieee80211_tx_status_ni + ieee80211_tx_status_irqsafe + ieee80211_rts_get + ieee80211_rts_duration + ieee80211_ctstoself_get + ieee80211_ctstoself_duration + ieee80211_generic_frame_duration + ieee80211_wake_queue + ieee80211_stop_queue + ieee80211_wake_queues + ieee80211_stop_queues + ieee80211_queue_stopped + +Frame filtering +=============== + +.. kernel-doc:: include/net/mac80211.h + :doc: Frame filtering + +.. kernel-doc:: include/net/mac80211.h + :functions: ieee80211_filter_flags + +The mac80211 workqueue +====================== + +.. kernel-doc:: include/net/mac80211.h + :doc: mac80211 workqueue + +.. kernel-doc:: include/net/mac80211.h + :functions: + ieee80211_queue_work + ieee80211_queue_delayed_work |
