From 2a32ad66da9e2b318bc994222441cdd38d2ef7ec Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Mon, 22 Dec 2014 20:41:19 +0200 Subject: [PATCH] HT: Fix 20/40 coex Action frame parsing Commit 5ce3ae4c8f2a07c28e0bbae1b68e5524ee034387 tried to clean up fetching a pointer to the action code field, but it forgot to add IEEE80211_HDRLEN to the pointer. This resulted in the coex report elements being read from too early in the frame.
