DMA TX buffers for MAC

Question asked by Michurin on Nov 25, 2012
Latest reply on Nov 25, 2012 by Michurin
Why application needs to copy ethernet frame to the TX buffer first and then DMA will move it to the MAC fifo? Why is it bad idea to set up DMA to read the frame directly from application? Just want to know the reason(s)

Thank you
