BF60x - EMAC/DMA question

Hi !

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.
