-Subject: [PATCH] src: support for flowtable listing
-
-This patch allows you to dump existing flowtable.
-
- # nft list ruleset
- table ip x {
- flowtable x {
- hook ingress priority 10
- devices = { eth0, tap0 }
- }
- }
-
-You can also list existing flowtables via:
-
- # nft list flowtables
- table ip x {
- flowtable x {
- hook ingress priority 10
- devices = { eth0, tap0 }
- }
- }
-
- You need a Linux kernel >= 4.16-rc to test this new feature.

-Subject: [PATCH] src: add support to add flowtables
-
-This patch allows you to create flowtable:
-
- # nft add table x
- # nft add flowtable x m { hook ingress priority 10\; devices = { eth0, wlan0 }\; }
-
-You have to specify hook and priority. So far, only the ingress hook is
-supported. The priority represents where this flowtable is placed in the
-ingress hook, which is registered to the devices that the user
-specifies.
-
-You can also use the 'create' command instead to bail out in case that
-there is an existing flowtable with this name.

-Subject: [PATCH] src: flow offload support
-
-This patch allows us to refer to existing flowtables:
-
- # nft add rule x x flow offload @m
-
-Packets matching this rule create an entry in the flow table 'm', hence,
-follow up packets that get to the flowtable at ingress bypass the
-classic forwarding path.

-+ Flowtables allow you to accelerate packet forwarding in software.
-+ Flowtables entries are represented through a tuple that is composed of the
-+ input interface, source and destination address, source and destination
-+ port; and layer 3/4 protocols. Each entry also caches the destination
-+ interface and the gateway address - to update the destination link-layer
-+ address - to forward packets. The ttl and hoplimit fields are also
-+ decremented. Hence, flowtables provides an alternative path that allow
-+ packets to bypass the classic forwarding path. Flowtables reside in the
-+ ingress hook, that is located before the prerouting hook. You can select
-+ what flows you want to offload through the <literal>flow offload</literal>
-+ expression from the <literal>forward</literal> chain. Flowtables are
-+ identified by their address family and their name. The address family
-+ must be one of
-+
-+ <simplelist type="inline">
-+ <member><literal>ip</literal></member>
-+ <member><literal>ip6</literal></member>
-+ <member><literal>inet</literal></member>
-+ </simplelist>.
-+
-+ The <literal>inet</literal> address family is a dummy family which is used to create
-+ hybrid IPv4/IPv6 tables.
-+
-+ When no address family is specified, <literal>ip</literal> is used by default.
