你好，在evt提供的例程中，有關于MACRAW發(fā)送的例子，那么要怎么接收macraw的數據呢？

uint32_t?MACRAW_Tx(uint8_t?*buff,?uint16_t?len)
{
?????/*?Check?if?the?descriptor?is?owned?by?the?ETHERNET?DMA?(when?set)?or?CPU?(when?reset)?*/
????if(?DMATxDescToSet->Status?&?ETH_DMATxDesc_OWN?)
????{
????????/*?Return?ERROR:?OWN?bit?set?*/
????????return?ETH_ERROR;
????}
????DMATxDescToSet->Status?|=?ETH_DMATxDesc_OWN;
????R16_ETH_ETXLN?=?len;
????R16_ETH_ETXST?=?(uint32_t)buff;
????R8_ETH_ECON1?|=?RB_ETH_ECON1_TXRTS;???????????????????????????????//start?sending
????/*?Update?the?ETHERNET?DMA?global?Tx?descriptor?with?next?Tx?descriptor?*/
????/*?Chained?Mode?*/
????/*?Selects?the?next?DMA?Tx?descriptor?list?for?next?buffer?to?send?*/
????DMATxDescToSet?=?(ETH_DMADESCTypeDef*)?(DMATxDescToSet->Buffer2NextDescAddr);
????/*?Return?SUCCESS?*/
????return?ETH_SUCCESS;
}

您好，在例程中有接收macraw的函數。(WCHNET_MainTask -->RecDataPolling)
