The TCP/UDP connection-tracking code in netfilter validates the

It seems at least part of this has already been merged in 2.6.12-rc

It would be great if the UDP code also would observeCHECKSUM_UNNECESSARY. I'll wait for 2.6.12 to appear and then submit anew patch if UDP has been missed.


 Thanks,
 Keir
