Well the Fedora Core policy with kernels is that it needs to go
upstream to be included in the kernel.. so for something like this
you'd be better joining the linux network mailing list and getting
some feedback from them and getting it upstreamed via them. Once its
hits the main kernel it'll be in Fedora.
