From 2ade5667e2e0244549818f16e2520141661e8bcd Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Wed, 28 Jan 2015 15:54:20 +0530 Subject: [PATCH] mwifiex: separate function for parsing head and tail IEs Head & Tail IEs are supposed to be added to beacon and probe response. This patch adds separate function for parsing head and tail IEs from cfg80211_beacon_data and sets them to FW.
