I know thats because of random bogosity coming in from the internet, and I really don't care. can I suppress that from filling up the dmesg buffer so I can see more important things like scsi soft errors?
You could try turning TCP window scaling off which should stop that part of the stack from executing.
How much it will affect the network performance of your box depends on the clients connecting to it...
