100G cmac UDP packets

Jump to solution

Hello,

I am trying to implement the UDP protocol on a standalone 100G cmac core.

If i follow the example design,  i have to write the header on the lbus concatenated with the data for TX.

For RX, i have to check if the MAC/IP addresses are the correct matches of pre-assigned ones.

Is there a way to assign this job to the cmac core, so that i can configure it to have a MAC address and an IP address, and tell it to accept only packets that are sent to him.

Hi

 

No, currently there is no SW or driver support for 100G CMAC core.

Hi

 

No, CMAC doesn't have any address filtering logic and it has to be implemented outside the core.

Hi ,

thanks for the feedback. By the way, is there any standalone library such as the LWIP that can help with this mac especially with DHCP/ARP and TCP/IP protocols.

should everything be hardware implemented?
