- Number of DMA receive buffers. Each buffer is 1600 bytes.
- These buffers are allocated dynamically.
- More buffers will increase throughput.
- If flow ctrl is enabled, make sure this number is larger than 9.

- help
- If this option is selected, a copy of each received buffer will be allocated from the heap
- before passing it to the IP Layer (L3).
- Which means, the total amount of received buffers is limited by the heap size.
- If this option is not selected, IP layer only uses the pointers to the DMA buffers owned by Ethernet MAC.
- When Ethernet MAC doesn't have any available buffers left, it will drop the incoming packets.

- help
- The emac driver uses an internal timer to check the Ethernet linkup status.
- Here you should choose a valid interval time.
