Questions about 10GE mac configuration and CRC inserting enabling in eth_e2e_e10

Hi JohnT,

Thanks for your feedback and support.

I have checked ccip_std_afu.sv ,and found that is a mapping module from CCIP MmioDin to Ethernet CSR.

But that is just a mapping module, which means the control source and source data is in the upper stream module, I think source is from c code in CPU side.

ccip_std_afu.sv works as a highspeed way to provide a road only, but data source, it can connect different modules but cannot know what data being delivered.

So with that ccip_std_afu.sv,still cann’t fig out what specific value being write to CSR. Thanks

Jim
