emac_esp_dma_flush_recv_frame() function

EMAC DMA handle

Copy received Ethernet frame from EMAC DMA memory space to application.

Get number of frames remaining in Rx DMA

Deletes the ESP EMAC DMA instance

Reset DMA

Transmit data from buffer over EMAC

Transmit data from multiple buffers over EMAC in single Ethernet frame. Data will be joint into single frame in order in which the buffers are stored in input array. @pre @p lengths array must have the same size as @p buffs array and their elements need to be stored in the same order, i.e. lengths[1] is a length associated with data buffer referenced at buffs[1] position.

Allocate buffer with size equal to actually received Ethernet frame size.
