ICMP echo

[proconsule]

Hi, thanks for this great project. I tried the UDP/IP stack with an ARRIA 10 SX (TERASIC HAN PILOT board) using quartus 21.1. All works good (UDP echo on port 1234 works very well and arp also) i know that icmp isn't supported, so i am trying to make it work (have ping makes connectivity test very easy) i used udp_complete_64 as starting point (since i am using a 10g fiber) but i cant figure out the packet flow.

` /*

• Input classifier (ip_protocol) */ wire s_select_udp = (ip_rx_ip_protocol == 8'h11); wire s_select_icmp = (ip_rx_ip_protocol == 8'h01 && ip_rx_ip_eth_type == 16'h0800); wire s_select_ip = !(s_select_udp || s_select_icmp); ` i tried with identify that a packet is an icmp ping with this to send to a custom icmp module (using udp_64 as reference)

have you any suggestion of a way to implement it in the right way (inside the ip_complete_64 module maybe?) or is the way i used the right way?

thanks

You can implement it on the IP layer. I have done the same and is working fine and tested on the board

Can you share the code?

I'm also curious. Could you add it to your public fork of verilog-ethernet?
