If I remember, by default netfilter is running on bridge. (without any rules).
And I had problem with packets dropped, because of too much traffic.

They are also security problem if it's enabled by default

I get the following warnings when booting with 3.10 kernel:

The patch does not really mention why we need this?

How can we avoid that warning?
