TX Example 1

In this example a single, 111-Byte Ethernet packet will be transmitted. This packet is divided into three

buffers. The three buffers are as follows:

Buffer 0:

„ 7-Byte “Data Start Offset”

„ 79-Bytes of payload data

„ 16-Byte “Buffer End Alignment”

Buffer 1:

„ 0-Byte “Data Start Offset”

„ 15-Bytes of payload data

„ 16-Byte “Buffer End Alignment”

Buffer 2:

„ 10-Byte “Data Start Offset”

„ 17-Bytes of payload data

„ 16-Byte “Buffer End Alignment”
