Exercises 3 cases: 1. no pmtu discovery (need to frag) 2. no PMTUd + NAT (don't flag packets as invalid from conntrack) 3. PMTU + NAT (need to send icmp error) The first two cases make sure we handle fragments correctly, i.e. pass them to classic forwarding path. Third case checks we offload everything (in the test case, PMTUd will kick in so all packets should be within link mtu). Nftables rules will filter packets that are supposed to be handled by the fast-path. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
