Need to change Fedora Linux's IPv6 stack for NDP DAD timer changes.
How to locate the Fedora's IPv6 and IPv4 stack in Fedora distribution dvd/site so that, we can recompile and generate new stack ?
"Fedora" doesn't have an IPv4/IPv6 stack. "Fedora" is a distribution -- a collection of tools and utilities. Fedora is built around "Linux", which does have a network stack. You can find the source code to Linux at kernel.org, where you can download everything as a tarball, or clone the git repository at git.kernel.org. The Kernel Hacker's Guide to Git has some useful information on getting started if you opt for this method.
