config DMA_RX_BUF_NUM
int "Number of DMA RX buffers"
range 3 20
default 10
help
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.
config DMA_TX_BUF_NUM
int "Number of DMA TX buffers"
range 3 20
default 10
help
Number of DMA transmit buffers. Each buffer is 1600 bytes.
These buffers are allocated dynamically.
More buffers will increase throughput.
config EMAC_L2_TO_L3_RX_BUF_MODE
bool "Enable received buffers be copied to Layer3 from Layer2"
default y
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.
config EMAC_CHECK_LINK_PERIOD_MS
int "Period (ms) of checking Ethernet linkup status"
range 1000 5000
default 2000
help
The emac driver uses an internal timer to check the Ethernet linkup status.
Here you should choose a valid interval time.
config EMAC_TASK_PRIORITY
int "EMAC_TASK_PRIORITY"
default 20
range 3 22
help
Priority of Ethernet MAC task.
config EMAC_TASK_STACK_SIZE
int "Stack Size of EMAC Task"
default 3072
range 2000 8000
help
Stack Size of Ethernet MAC task.
