Hi Kunwu,
nf is for fixes for Netfilter (which includes IPVS). The target tree is nf.git
nf-next is for non-fixes for Netfilter. The target tree if nf-next.git
net is for fixes for Networking code, which does not have a more specific
tree (as is the case for Netfilter). The target tree is net.git.
Liikewise, net-next is for non-fixes for Networking code.
The target tree is net-next.git
The MAINTAINERS file, and get_maintainers.pl script are useful here.
nf is merged into net on request from the Netfilter maintainers,
this is it's path to released kernels.
Likewise, nf-next is merged into net-next.
