Recently our Nagios started reported network interface errors on few servers and I have no idea how to identify what caused these errors.
I collected some information here and hope someone can provide some advice.

SolarFlare user guide just says rx_tcp_udp_chksum_err
Number of packets received with TCP/UDP checksum error.
How do I troubleshoot this?
