These buffers are allocated dynamically.

More buffers will increase throughput.

If flow ctrl is enabled, make sure this number is larger than 9.

|
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.

The emac driver uses an internal timer to check the Ethernet linkup status.

Here you should choose a valid interval time.
