From b6f1b24448de1d294f9668b14bf02391ff6bef5c Mon Sep 17 00:00:00 2001

Subject: [PATCH 71/91] net: mediatek: mtk_cal_txd_req() returns bad value
The code used to also support the PDMA engine, which had 2 packet pointers
per descriptor. Because of this we have to divide the result by 2 and round
it up. This is no longer needed as the code only supports QDMA.
