4.1) Transmit process
|

When the driver's transmit routine is called by the kernel, it sets up a
|
||||
transmit descriptor by calling the underlying DMA transmit routine (SGDMA or

MSGDMA), and initites a transmit operation. Once the transmit is complete, an

resource required to send and track the requested transmit operation.
