From 5eb02e44adc92a71bae3ff60acb1eea5ada14e93 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Fri, 24 Feb 2012 21:36:04 -0800 Subject: [PATCH] mwifiex: remove unnecessary enum MWIFIEX_802_11_WEP_STATUS Instead of defining an 'enum', we can simply use 'u8' flag for WEP status. Rename 'wep_status' to 'wep_enabled' to match with 'wpa_enabled' and 'wpa2_enabled'. Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
