Subject: [PATCH V2 2/8] net: mediatek: mtk_cal_txd_req() returns bad value
Date: Thu, 7 Apr 2016 21:26:44 +0200 [thread overview]
Message-ID: <1460057210-55786-3-git-send-email-blogic@openwrt.org> (raw)
In-Reply-To: <1460057210-55786-1-git-send-email-blogic@openwrt.org>
The code used to also support the PDMA engine, which had 2 packet pointers
per descriptor. Because of this we had to divide the result by 2 and round
it up. This is no longer needed as the code only supports QDMA.
