[PATCH V3 2/8] net: mediatek: mtk_cal_txd_req() returns bad value

From: John Crispin
Date: Fri Apr 08 2016 - 03:52:59 EST


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.
