Subject: [PATCH v2 05/11] rtlwifi: Implement rtl_get_tx_hw_rate to yield correct hw_rate
Date: Mon, 17 Jul 2017 10:09:48 -0500	[thread overview]
Message-ID: <20170717150954.1441-6-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20170717150954.1441-1-Larry.Finger@lwfinger.net>

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

Originally, we get legacy rate only, so we extend to get HT and VHT rate.
