From 7d8cc7a4bbcda5d094aec6e33e9223c621bc4f87 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Tue, 3 Jun 2014 23:41:22 +0200 Subject: [PATCH] staging: rtl8723au: rtw_update_ht_cap23a(): Use correct mask when determining 40MHz channel location commit c85f70d55f7fa6d24f8d77aa736526e5a7974815 Author: Jes Sorensen Date: Tue May 27 13:43:12 2014 +0200 staging: rtl8723au: Eliminate struct HT_info_element Yet another duplicate version of struct ieee80211_ht_operation Signed-off-by: Jes Sorensen introduced a bad error, applying the wrong value as the mask when determining the location of the 40MHz channel, effectively making it always determining it as not present. This caused hangs and delays when running in 40MHz channel mode. This should get it right.
