Subject: [PATCH 02/11 V3] rtlwifi: Set retry limit depends on vif type.
Date: Fri,  3 Feb 2017 11:32:23 -0600	[thread overview]
Message-ID: <20170120212716.29887-3-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20170120212716.29887-1-Larry.Finger@lwfinger.net>
In-Reply-To: <20170120212716.29887-1-Larry.Finger@lwfinger.net>
In-Reply-To: <20170120212716.29887-1-Larry.Finger@lwfinger.net>

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

We assign different retry limit according to vif type, because
it can boost performance in field.
