Need to discard IPv6 martian packets #107
For a long time, we've had a TODO we've been forgetting. That is because it's written away in the Basic Runs tutorial, not here.
Basically, the RFC wants us to always discard martian packets.
We currently avoid them by asking users to issue the following command:
Not sure why I can't find an IPv6 equivalent. Perhaps they are always discarded, regardless of configuration. We need to make sure and update Jool or the documentation accordingly.
Logging martians does not actually discard them; we were oddly misinformed.
In practice, getting rid of martian packets is a firewall concern, which pretty much renders this issue a duplicate of #41.
As such, no code was added, but we're removing the log_martians sysctl from the manual.
