Subject: [PATCH 05/11] rtlwifi: btcoex: 23b 2ant: wifi is not actually off in mp mode
Date: Thu,  6 Apr 2017 15:19:52 -0500	[thread overview]
Message-ID: <20170406201958.25642-6-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20170406201958.25642-1-Larry.Finger@lwfinger.net>

From: Yan-Hsuan Chuang <yhchuang@realtek.com>

In mp mode, the wifi will not turn off and still has control of the PTA,
so the driver needs to distinguish whether it is mp mode or not
