Re: [casper] arp: unknown or malformed arp packet

[casper] arp: unknown or malformed arp packet

Hi All, We are seeing, "arp: unknown or malformed arp packet" messages on ROACH2 board, quite frequently. In our setup, we have ROACH2 board sending data out via a 40G switch. Sometimes the data is broadcast from ROACH2 boards instead of sending to a particular ip address. The 10GbE core
