Get header length from data
unsigned int ieee80211_get_hdrlen_from_skb(const struct sk_buff * skb);
skb
the frame
Given an skb with a raw 802.11 header at the data pointer this function returns the 802.11 header length.
The 802.11 header length in bytes (not including encryption headers). Or 0 if the data in the sk_buff is too short to contain a valid 802.11 header.
