They mean that the incoming data packet was corrupt - or at least it
failed its checksum. The masq code used to just rewrite the packet
headers and force the checksum to be right (thus falsely validating
corrupt data), it now drops corrupt packets on the floor and
generates that kernel message.
It should probably do something else - update the error counts on the
interface?, inform in a more useful fashion?, not fill up the syslog!
Basically if its occaisional then ignore the message.
If its regular then the other end may be broken.
If its regular and distributed over many hosts start checking your
ethernet or other net connections!
