Subject: [PATCH v2 2/8] rtlwifi: Do IQK only once to reduce wifi occupy antenna
Date: Wed, 21 Jun 2017 12:15:32 -0500	[thread overview]
Message-ID: <20170621171538.4462-3-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20170621171538.4462-1-Larry.Finger@lwfinger.net>

From: Ping-Ke Shih <pkshih@realtek.com>

Modify 8723be and 8192e only.
8812/8821 do IQK in DM, so we may do it later.
