+
+Driver Compilation
+------------------
+
+To compile LiquidIO PMD for Linux x86_64 gcc target, run the following "make"
+command:
+
+.. code-block:: console
+
+   cd <DPDK-source-directory>
+   make install T=x86_64-native-linuxapp-gcc
+
+
+Sample Application Notes
+------------------------
+
+This section demonstrates how to launch ``testpmd`` with LiquidIO® CN23X0
+device managed by ``librte_pmd_lio`` in Linux operating system.
+
+#. Mount huge pages:
+
+   .. code-block:: console
+
+      mkdir /mnt/huge
+      mount -t hugetlbfs nodev /mnt/huge
+
+#. Request huge pages:
+
+   .. code-block:: console
+
+      echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/nr_hugepages
+
+#. Load ``vfio-pci`` driver:
+
+   .. code-block:: console
+
+      modprobe vfio-pci
+
+#. Bind the LiquidIO VFs to ``vfio-pci`` loaded in previous step:
+
+   Setup VFIO permissions for regular users and then bind to ``vfio-pci``:
+
+   .. code-block:: console
+
+      sudo chmod a+x /dev/vfio
+
+      sudo chmod 0666 /dev/vfio/*
+
+      ./usertools/dpdk-devbind.py --bind vfio-pci 0000:03:00.3 0000:03:08.3
+
+#. Start ``testpmd`` with basic parameters:
+
+   .. code-block:: console
+
+      ./build/app/testpmd -c 0xf -n 4 -- -i
+
+   Example output:
+
+   .. code-block:: console
+
+      [...]

+      EAL:   probe driver: 177d:9712 net_liovf

+
+SR-IOV: Prerequisites and Sample Application Notes
+--------------------------------------------------
+
+This section provides instructions to configure SR-IOV with Linux OS.
+
+#. Verify SR-IOV and ARI capabilities are enabled on the adapter using ``lspci``:
+
+   .. code-block:: console
+
+      lspci -s <slot> -vvv
+
+   Example output:
+
+   .. code-block:: console
+
+      [...]
+      Capabilities: [148 v1] Alternative Routing-ID Interpretation (ARI)
+      [...]
+      Capabilities: [178 v1] Single Root I/O Virtualization (SR-IOV)
+      [...]
+      Kernel driver in use: LiquidIO
+
+#. Load the kernel module:
+
+   .. code-block:: console
+
+      modprobe liquidio
+
+#. Bring up the PF ports:
+
+   .. code-block:: console
+
+      ifconfig p4p1 up
+      ifconfig p4p2 up
+
+#. Change PF MTU if required:
+
+   .. code-block:: console
+
+      ifconfig p4p1 mtu 9000
+      ifconfig p4p2 mtu 9000
+
+#. Create VF device(s):
+
+   Echo number of VFs to be created into ``"sriov_numvfs"`` sysfs entry
+   of the parent PF.
+
+   .. code-block:: console
+
+      echo 1 > /sys/bus/pci/devices/0000:03:00.0/sriov_numvfs
+      echo 1 > /sys/bus/pci/devices/0000:03:00.1/sriov_numvfs
+
+
+#. Assign VF MAC address:
+
+   Assign MAC address to the VF using iproute2 utility. The syntax is::
+
+      ip link set <PF iface> vf <VF id> mac <macaddr>
+
+   Example output:
+
+   .. code-block:: console
+
+      ip link set p4p1 vf 0 mac F2:A8:1B:5E:B4:66
+
+
+#. Assign VF(s) to VM.
+
+   The VF devices may be passed through to the guest VM using qemu or
+   virt-manager or virsh etc.
+
+   Example qemu guest launch command:
+
+   .. code-block:: console
+
+      ./qemu-system-x86_64 -name lio-vm -machine accel=kvm \
+      -cpu host -m 4096 -smp 4 \
+      -drive file=<disk_file>,if=none,id=disk1,format=<type> \
+      -device virtio-blk-pci,scsi=off,drive=disk1,id=virtio-disk1,bootindex=1 \
+      -device vfio-pci,host=03:00.3 -device vfio-pci,host=03:08.3
+
+
+#. Running testpmd
+
+   Refer :ref:`notes above <lio_driver-compilation>`
+   to compile and run ``testpmd`` application.
+   Use ``igb_uio`` instead of ``vfio-pci`` in VM.
+
+
+Limitations
+-----------
+
+VF MTU
+~~~~~~
+
+VF MTU is limited by PF MTU. Raise PF value before configuring VF for larger packet size.
+
+VLAN offload
+~~~~~~~~~~~~
+
+Tx VLAN insertion is not supported and consequently VLAN offload feature is
+marked partial.
+
+Ring size
+~~~~~~~~~
+
+Number of descriptors for Rx/Tx ring should be in the range 128 to 512.
