Subject: [PATCH 12/14] rtlwifi: btcoex: 21a 1ant: monitor bt profiling when scan
Date: Mon, 10 Apr 2017 11:23:08 -0500	[thread overview]
Message-ID: <20170410162310.7515-13-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20170410162310.7515-1-Larry.Finger@lwfinger.net>

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

When wifi is scanning and not connected, set the tdma and coex table
properly to control the priority of the packets to make the wifi bt
coexistence operate smoothly
