ieee80211_generic_frame_duration - Calculate the duration field for a frame : pointer obtained from ieee80211_alloc_hw(). : &struct ieee80211_vif pointer from &struct ieee80211_if_init_conf. : the length of the frame. : the rate (in 100kbps) at which the frame is going to be transmitted.
Calculate the duration field of some generic frame, given its length and transmission rate (in 100kbps).

ieee80211_get_hdrlen_from_skb - get header length from data
Given an skb with a raw 802.11 header at the data pointer this function returns the 802.11 header length in bytes (not including encryption headers). If the data in the sk_buff is too short to contain a valid 802.11 header the function returns 0.

ieee80211_is_erp_rate - Check if a rate is an ERP rate : The PHY-mode for this rate : Transmission rate to check, in 100 kbps
Check if a given rate is an Extended Rate PHY (ERP) rate.
