Subject: [PATCH 02/10] rtlwifi: fix scan channel 1 fail after IPS
Date: Wed, 10 Jan 2018 13:19:54 +0800 [thread overview]
Message-ID: <20180110052002.9544-3-pkshih@realtek.com> (raw)
In-Reply-To: <20180110052002.9544-1-pkshih@realtek.com>
From: Ping-Ke Shih <pkshih@realtek.com>
If there is no connection, driver will enter IPS state. Meanwhile, it
fails to scan channel 1 by the command 'iw dev wlan0 scan freq 2412',
because hardware channel setting lose after IPS. Thus, restore channel
setting from hw->conf.channel set by last rtl_op_config().
