e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * Interaction steps for 802.11e/n between net80211 module
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * and iwh driver:
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- setup link with 802.11n AP: net80211 module is responsible
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * for setup link with 802.11n AP. iwh driver monitors current
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * state and make relevant configurations according work mode.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- QoS parameter updating: net80211 module is responsible for
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * extract EDCA parameters from the fram of AP, iwh driver get
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * these parameters and make relevant configuration to HW.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- TX queue management: iwh driver place a frame into suitable
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * TX queue according to frame type and user priority extracted
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * from frame head.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- MIMO: iwh driver make relevant configurations in TX and RX
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * direction according to AP mode from net80211 module.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- Link aggregation: AMSDU is implemented by net80211 module and
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * AMPDU is implemented by both iwh driver and net80211 module.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * iwh driver distinguish frames in one AMPDU frame and net80211
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * module is responsible reordering every frame.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- Block ACK: net80211 module is responsible for setup agreement
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * with AP and iwh driver is responsible for realistic ACK.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- Rate scaling: This function is implemented independently by
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * iwh driver.
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * -- HT protection: This feature is also implemented by iwh driver
e2cf88ac9d753a00c17aa235f6afdc76574fe3a6Quaker Fang * no interaction with net80211 module.
