It's generally considered a Bad Idea, as it's almost certainly easier to
do in userspace. If you're trying to to instrument a network-based monitoring
system and need access to kernel data, you're *much* better off having the
kernel export the data via netlink or even abuse of /proc or /sys, and then
a small userspace program read the data and ship it over the net. There's
a *lot* of things that you just won't have access to in kernel space (for
starters, you don't have a DNS resolver, so you can't use hostnames for
configuration).

If you're determined to do this in kernelspace anyhow, see the
linux-2.6-tux.patch in recent RedHat/Fedora kernels, and ask yourself why
that patch has no hope of being accepted upstream (although I have a great
amount of respect for a lot of things that come out of RedHat, *that* patch
is best described "a fully RFC1925-compliant networking pig, with afterburners")
