This patch adds the IPv4 flow table type, that implements the datapath flow table to forward IPv4 traffic. Rationale is: 1) Look up for the packet in the flow table, from the ingress hook. 2) If there's a hit, decrement ttl and pass it on to the neighbour layer for transmission. 3) If there's a miss, packet is passed up to the classic forwarding path. This patch also supports layer 3 source and destination NAT. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
