1=========================== 2mac80211 subsystem (basics) 3=========================== 4 5You should read and understand the information contained within this 6part of the book while implementing a mac80211 driver. In some chapters, 7advanced usage is noted, those may be skipped if this isn't needed. 8 9This part of the book only covers station and monitor mode 10functionality, additional information required to implement the other 11modes is covered in the second part of the book. 12 13Basic hardware handling 14======================= 15 16TBD 17 18This chapter shall contain information on getting a hw struct allocated 19and registered with mac80211. 20 21Since it is required to allocate rates/modes before registering a hw 22struct, this chapter shall also contain information on setting up the 23rate/mode structs. 24 25Additionally, some discussion about the callbacks and the general 26programming model should be in here, including the definition of 27ieee80211_ops which will be referred to a lot. 28 29Finally, a discussion of hardware capabilities should be done with 30references to other parts of the book. 31 32.. kernel-doc:: include/net/mac80211.h 33 :functions: 34 ieee80211_hw 35 ieee80211_hw_flags 36 SET_IEEE80211_DEV 37 SET_IEEE80211_PERM_ADDR 38 ieee80211_ops 39 ieee80211_alloc_hw 40 ieee80211_register_hw 41 ieee80211_unregister_hw 42 ieee80211_free_hw 43 44PHY configuration 45================= 46 47TBD 48 49This chapter should describe PHY handling including start/stop callbacks 50and the various structures used. 51 52.. kernel-doc:: include/net/mac80211.h 53 :functions: 54 ieee80211_conf 55 ieee80211_conf_flags 56 57Virtual interfaces 58================== 59 60TBD 61 62This chapter should describe virtual interface basics that are relevant 63to the driver (VLANs, MGMT etc are not.) It should explain the use of 64the add_iface/remove_iface callbacks as well as the interface 65configuration callbacks. 66 67Things related to AP mode should be discussed there. 68 69Things related to supporting multiple interfaces should be in the 70appropriate chapter, a BIG FAT note should be here about this though and 71the recommendation to allow only a single interface in STA mode at 72first! 73 74.. kernel-doc:: include/net/mac80211.h 75 :functions: ieee80211_vif 76 77Receive and transmit processing 78=============================== 79 80what should be here 81------------------- 82 83TBD 84 85This should describe the receive and transmit paths in mac80211/the 86drivers as well as transmit status handling. 87 88Frame format 89------------ 90 91.. kernel-doc:: include/net/mac80211.h 92 :doc: Frame format 93 94Packet alignment 95---------------- 96 97.. kernel-doc:: net/mac80211/rx.c 98 :doc: Packet alignment 99 100Calling into mac80211 from interrupts 101------------------------------------- 102 103.. kernel-doc:: include/net/mac80211.h 104 :doc: Calling mac80211 from interrupts 105 106functions/definitions 107--------------------- 108 109.. kernel-doc:: include/net/mac80211.h 110 :functions: 111 ieee80211_rx_status 112 mac80211_rx_encoding_flags 113 mac80211_rx_flags 114 mac80211_tx_info_flags 115 mac80211_tx_control_flags 116 mac80211_rate_control_flags 117 ieee80211_tx_rate 118 ieee80211_tx_info 119 ieee80211_tx_info_clear_status 120 ieee80211_rx 121 ieee80211_rx_ni 122 ieee80211_rx_irqsafe 123 ieee80211_tx_status 124 ieee80211_tx_status_ni 125 ieee80211_tx_status_irqsafe 126 ieee80211_rts_get 127 ieee80211_rts_duration 128 ieee80211_ctstoself_get 129 ieee80211_ctstoself_duration 130 ieee80211_generic_frame_duration 131 ieee80211_wake_queue 132 ieee80211_stop_queue 133 ieee80211_wake_queues 134 ieee80211_stop_queues 135 ieee80211_queue_stopped 136 137Frame filtering 138=============== 139 140.. kernel-doc:: include/net/mac80211.h 141 :doc: Frame filtering 142 143.. kernel-doc:: include/net/mac80211.h 144 :functions: ieee80211_filter_flags 145 146The mac80211 workqueue 147====================== 148 149.. kernel-doc:: include/net/mac80211.h 150 :doc: mac80211 workqueue 151 152.. kernel-doc:: include/net/mac80211.h 153 :functions: 154 ieee80211_queue_work 155 ieee80211_queue_delayed_work 156
