+filter on a port::

+ testpmd> rx_vxlan_port add 4789 0
+
+Create VXLAN rules on port 0 to steer traffic to PF queues.

+
+::
+
+ testpmd> flow create 0 ingress pattern integrity value mask 1 value spec 0 / end actions queue index 0 / end
+
+Sample conntrack rules
+~~~~~~~~~~~~~~~~~~~~~~
+
+Conntrack rules can be set by the following commands
+
+Need to construct the connection context with provided information.
+In the first table, create a flow rule by using conntrack action and jump to
+the next table. In the next table, create a rule to check the state.
+
+::
+
+ testpmd> set conntrack com peer 1 is_orig 1 enable 1 live 1 sack 1 cack 0
+ last_dir 0 liberal 0 state 1 max_ack_win 7 r_lim 5 last_win 510

+ testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
+
+Construct the conntrack again with only "is_orig" set to 0 (other fields are
+ignored), then use "update" interface to update the direction. Create flow
+rules like above for the peer port.
+
+::
+
+ testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end
+
+Sample meter with policy rules
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Meter with policy rules can be created by the following commands:
+
+Need to create policy first and actions are set for green/yellow/red colors.
+Create meter with policy id. Create flow with meter id.
+
+Example for policy with meter color action. The purpose is to color the packet
+to reflect the meter color result.
+The meter policy action list: ``green -> green, yellow -> yellow, red -> red``.
+
+::
+
+ testpmd> add port meter profile srtcm_rfc2697 0 13 21504 2688 0 0
+ testpmd> add port meter policy 0 1 g_actions color type green / end y_actions color type yellow / end
+ r_actions color type red / end
+ testpmd> create port meter 0 1 13 1 yes 0xffff 0 0
+ testpmd> flow create 0 priority 0 ingress group 1 pattern eth / end actions meter mtr_id 1 / end
+
+BPF Functions
+--------------
+
+The following sections show functions to load/unload eBPF based filters.
+
+bpf-load
+~~~~~~~~
+
+Load an eBPF program as a callback for particular RX/TX queue::
+
+ testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
+
+The available load-flags are:
+
+* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
+
+* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
+
+* ``-``: none.
+
+.. note::
+
+ You'll need clang v3.7 or above to build bpf program you'd like to load
+
+For example:
+
+.. code-block:: console
+
+ cd examples/bpf
+ clang -O2 -target bpf -c t1.c
+
+Then to load (and JIT compile) t1.o at RX queue 0, port 1:
+
+.. code-block:: console
+
+ testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
+
+To load (not JITed) t1.o at TX queue 0, port 0:
+
+.. code-block:: console
+
+ testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
+
+bpf-unload
+~~~~~~~~~~
+
+Unload previously loaded eBPF program for particular RX/TX queue::
+
+ testpmd> bpf-unload rx|tx (portid) (queueid)
+
+For example to unload BPF filter from TX queue 0, port 0:
+
+.. code-block:: console
+
+ testpmd> bpf-unload tx 0 0
