Number of DMA receive buffers. Each buffer is 1600 bytes.

Buffers are allocated statically.

Larger number of buffers increases throughput.

If enable flow ctrl, the num must be above 9 .

If this options is selected, a copy of each received buffer will be created when
|
|
passing it from the Ethernet MAC (L2) to the IP stack (L3). Otherwise, IP stack
|
|
will receive pointers to the DMA buffers used by Ethernet MAC.
|
|
|
|
When Ethernet MAC doesn't have any unused buffers left, it will drop incomming
|
|
packets (flow control may help with this problem, to some extent).
|
|
|
|
The buffers for the IP stack are allocated from the heap, so the total number of
|
|
receive buffers is limited by the available heap size, if this option is selected.
|
|
|
|
If unsure, choose n.
