[dpdk-dev] [PATCH v2 09/10] doc: refer PMD compile and test section from qede doc

Refer the section which explains driver compilation and running of
testpmd in Linux, instead of describing it in driver documentation.

-~~~~~~~~~~~~~~~~~~
+Driver compilation and testing
+------------------------------
 
-To compile QEDE PMD for Linux x86_64 gcc target, run the following ``make``
-command::
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
 
-   cd <DPDK-source-directory>
-   make config T=x86_64-native-linuxapp-gcc install

+--------------------------------------------------
 
-To compile QEDE PMD for Linux x86_64 clang target, run the following ``make``
-command::
+This section provides instructions to configure SR-IOV with Linux OS.
 
-   cd <DPDK-source-directory>
-   make config T=x86_64-native-linuxapp-clang install
+**Note**: librte_pmd_qede will be used to bind to SR-IOV VF device and Linux native kernel driver (QEDE) will function as SR-IOV PF driver. Requires PF driver to be 8.10.x.x or higher.
 
-To compile QEDE PMD for FreeBSD x86_64 clang target, run the following ``gmake``
-command::
+#. Verify SR-IOV and ARI capability is enabled on the adapter using ``lspci``:
 
-   cd <DPDK-source-directory>

+#. Load the kernel module:
 
-#. Request huge pages:
+   .. code-block:: console
+
+      modprobe qede
+
+   Example output:
 
    .. code-block:: console
 
-      echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/ \
-                                                                nr_hugepages

+      systemd-udevd[4848]: renamed network interface eth1 to ens5f1
 
-#. Load ``igb_uio`` driver:
+#. Bring up the PF ports:
 
    .. code-block:: console
 
-      insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
+      ifconfig ens5f0 up
+      ifconfig ens5f1 up
+
+#. Create VF device(s):
+
+   Echo the number of VFs to be created into ``"sriov_numvfs"`` sysfs entry
+   of the parent PF.
 
-#. Bind the QLogic 4xxxx adapters to ``igb_uio`` loaded in the
-   previous step:
+   Example output:
 
    .. code-block:: console
 
-      ./usertools/dpdk-devbind.py --bind igb_uio 0000:84:00.0 0000:84:00.1 \

+      echo 2 > /sys/devices/pci0000:00/0000:00:03.0/0000:81:00.0/sriov_numvfs
 
-#. Start ``testpmd`` with basic parameters:
-   (Enable QEDE_DEBUG_INFO=y to view informational messages)
+
+#. 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 ens5f0 vf 0 mac 52:54:00:2f:9d:e8
+
+
+#. PCI Passthrough:
+
+   The VF devices may be passed through to the guest VM using ``virt-manager`` or
+   ``virsh``. QEDE PMD should be used to bind the VF devices in the guest VM
+   using the instructions from Driver compilation and testing section above.
+
