From 71ba186c123630ddab17667ec9ecf7e2ef211295 Mon Sep 17 00:00:00 2001 From: Vivek Natarajan <vnatarajan@atheros.com> Date: Thu, 12 Aug 2010 14:23:28 +0530 Subject: [PATCH] ath9k_htc: Fix disconnect issue in HT40 mode. Some APs advertise that they may be HT40 capable in the capabilites but the current operating channel configuration may be only HT20. This causes disconnection as ath9k_htc sets WLAN_RC_40_FLAG despite the AP operating in HT20 mode. Hence set this flag only if the current channel configuration is HT40 enabled.
