Subject: [PATCH 3/9] net: mediatek: mtk_cal_txd_req() returns bad value
Date: Thu,  7 Apr 2016 19:57:50 +0200	[thread overview]
Message-ID: <1460051876-53135-3-git-send-email-blogic@openwrt.org> (raw)
In-Reply-To: <1460051876-53135-1-git-send-email-blogic-p3rKhJxN3npAfugRpC6u6w@public.gmane.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.
