Will match any ipv4 packet (VLAN included).
+- When using DV flow engine (``dv_flow_en`` = 1), flow pattern without VLAN item
+ will match untagged packets only.
+ The flow rule::
+
+ flow create 0 ingress pattern eth / ipv4 / end ...
+
+ Will match untagged packets only.
+ The flow rule::
+
+ flow create 0 ingress pattern eth / vlan / ipv4 / end ...
+
+ Will match tagged packets only, with any VLAN ID value.
+ The flow rule::
+
+ flow create 0 ingress pattern eth / vlan vid is 3 / ipv4 / end ...
+
+ Will only match tagged packets with VLAN ID 3.

- VLAN pop offload command:
- Flow rules having a VLAN pop offload command as one of their actions and
- Match on GTP tunnel header item supports the following fields only:
+ - v_pt_rsv_flags: E flag, S flag, PN flag
- msg_type
- teid
- **ethtool** operations on related kernel interfaces also affect the PMD.
+Run as non-root
+^^^^^^^^^^^^^^^
+
+In order to run as a non-root user,
+some capabilities must be granted to the application::
+
+ setcap cap_sys_admin,cap_net_admin,cap_net_raw,cap_ipc_lock+ep <dpdk-app>
+
+Below are the reasons of the need for each capability:
+
+``cap_sys_admin``
+ When using physical addresses (PA mode), with Linux >= 4.0,
+ for access to ``/proc/self/pagemap``.
+
+``cap_net_admin``
+ For device configuration.
+
+``cap_net_raw``
+ For raw ethernet queue allocation through kernel driver.
+
+``cap_ipc_lock``
+ For DMA memory pinning.
+
+Driver options
+^^^^^^^^^^^^^^

- ``rxq_cqe_comp_en`` parameter [int]
A nonzero value enables the compression of CQE on RX side. This feature
