Trispeed Ethernet: Do I have to manually include preamble and SFD?

Hi, as the title says, for an Ethernet transfer, which packets lands on the SOP? Is it the start of the preamble or MAC destination address?  

 

Thanks for your time.

Hi, 

 

When you write your program, you would start with the MAC destination address. Check this link https://gist.github.com/austinmarton/1922600

The socket commands add the preamble and SFD. On the receiver side, the TSE MAC strips the SFD and Preamble, so you would see SOP on the first byte of the destination address.
