@Note: This interface is implemented to operate in zero-copy mode only:
|
|
|
|
- Rx buffers are allocated statically and passed directly to the LwIP stack
|
|
|
|
they will return back to DMA after been processed by the stack.
|
|
|
|
- Tx Buffers will be allocated from LwIP stack memory heap,
|
|
|
|
then passed to ETH HAL driver.
|
|
|
|
|
|
|
|
@Notes:
|
|
|
|
1.a. ETH DMA Rx descriptors must be contiguous, the default count is 4,
|
|
|
|
to customize it please redefine ETH_RX_DESC_CNT in stm32xxxx_hal_conf.h
|
|
|
|
1.b. ETH DMA Tx descriptors must be contiguous, the default count is 4,
|
|
|
|
to customize it please redefine ETH_TX_DESC_CNT in stm32xxxx_hal_conf.h
|
|
|
|
|
|
|
|
2.a. Rx Buffers number must be between ETH_RX_DESC_CNT and 2*ETH_RX_DESC_CNT
|
|
|
|
2.b. Rx Buffers must have the same size: ETH_RX_BUFFER_SIZE, this value must
|
|
|
|
passed to ETH DMA in the init field (EthHandle.Init.RxBuffLen)
