In the EMAC-functional description of the HR-manual (BF60x) on page 23-85 there is
a statement in section DMA Initialization
7. Ensure that the software creates three or more different tx or rx descriptors...
why should there 3 or more? if I copy the received frames immediately there should no problem if I use
2 buffers (ping/pong).
please correct me if I'm wrong or there is a special background behind this demand.
