Subject: [PATCH 063/102] 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.
