Payload Length in Small 10/100 MAC

Hello, 

 

We are using Custom Cylcone-IV board and currently testing Ethernet using small 10/100 MAC. I went through TSE MAC user guide of Altera, and i understand that length/type is part of the frame, i also understand that maximum frame length is fixed with 1518 in small MAC and its read only register.  

 

Do i have to set the payload length of the Ethernet frame manually? If so how do i do it. 

 

Thanks

What exactly do you want to achieve? The size of a given frame is defined by the Avalon Stream signals themselves, with the "start of packet" and "end of packet" signals. AFAIK this register you are talking about is just used inside the TSE to discard frames that are too long.
