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