If the driver for your network card supports transmit and/or receive checksum offloading, Linux may not be calculating or verifying these values. The hardware internal to your network card will do that work instead.
You should be able to use ethtool to toggle this behavior on and off. Someone other than me may also be able to tell you if that behavior changed by default for your network card between F14 and F15 given the model of the network card and driver used.
It might also be useful if you could explain to the list the exact nature of the problems you are having with Network Manager.

I upgrade my desktop (Acer ASE380) from Fedora 14 to F15. Unfortunately, the network has issue with "bad udp cksum" using tcpdump. -vv command. How to resolve that problem?
NetworkManager caused a lot of trouble since I moved to F15 on Toshiba Satelitte C650D (Fusion version).
Thanks for help.
