I am getting (bad udp cksum) in lo interface how to fix it?

[isslam]

i gets these packets from lo interface:

is there option or command to disable udp checksum to avoid packets loss ?

[trendy]

There isn't any packet loss. Most likely this is due to Linux turning off IP checksumming on the loopback device for performance.
