From a160c7846e1f81b5cd6c5d0fbe5c1f8757e8884b Mon Sep 17 00:00:00 2001

Subject: [PATCH 66/66] net-next: 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.
