8 The QEDE poll mode driver library (**librte_net_qede**) implements support
9 for **QLogic FastLinQ QL4xxxx 10G/25G/40G/50G/100G Intelligent Ethernet Adapters (IEA) and Converged Network Adapters (CNA)** family of adapters as well as SR-IOV virtual functions (VF). It is supported on
10 several standard Linux distros like RHEL, SLES, Ubuntu etc.
11 It is compile-tested under FreeBSD OS.
13 More information can be found at `QLogic Corporation's Website
14 <http://www.qlogic.com>`_.

22 - Port hardware statistics
24 - Multiple MAC address

32 - Stateless checksum offloads (IPv4/IPv6/TCP/UDP)
34 - VLAN offload - Filtering and stripping
35 - N-tuple filter and flow director (limited support)

44 Co-existence considerations
45 ---------------------------
47 - QLogic FastLinQ QL4xxxx CNAs support Ethernet, RDMA, iSCSI and FCoE
48 functionalities. These functionalities are supported using
49 QLogic Linux kernel drivers qed, qede, qedr, qedi and qedf. DPDK is
50 supported on these adapters using qede PMD.
52 - When SR-IOV is not enabled on the adapter,
53 QLogic Linux kernel drivers (qed, qede, qedr, qedi and qedf) and qede
54 PMD can’t be attached to different PFs on a given QLogic FastLinQ
56 A given adapter needs to be completely used by DPDK or Linux drivers
57 Before binding DPDK driver to one or more PFs on the adapter,
58 please make sure to unbind Linux drivers from all PFs of the adapter.
59 If there are multiple adapters on the system, one or more adapters
60 can be used by DPDK driver completely and other adapters can be used
61 by Linux drivers completely.
63 - When SR-IOV is enabled on the adapter,
64 Linux kernel drivers (qed, qede, qedr, qedi and qedf) can be bound
65 to the PFs of a given adapter and either qede PMD or Linux drivers
66 (qed and qede) can be bound to the VFs of the adapter.
68 - For sharing an adapter between DPDK and Linux drivers, SRIOV needs
69 to be enabled. Bind all the PFs to Linux Drivers(qed/qede). Create
70 a VF on PFs where DPDK is desired and bind these VFs to qede_pmd.
71 Binding of PFs simultaneously to DPDK and Linux drivers on a given
72 adapter is not supported.
74 Supported QLogic Adapters
75 -------------------------
77 - QLogic FastLinQ QL4xxxx 10G/25G/40G/50G/100G Intelligent Ethernet Adapters (IEA) and Converged Network Adapters (CNA)
82 - Requires storm firmware version **8.40.33.0**. Firmware may be available
83 inbox in certain newer Linux distros under the standard directory
84 ``E.g. /lib/firmware/qed/qed_init_values-8.40.33.0.bin``.
85 If the required firmware files are not available then download it from
86 `linux-firmware git repository <http://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qed>`_.
88 - Requires the NIC be updated minimally with **8.30.x.x** Management firmware(MFW) version supported for that NIC.
89 It is highly recommended that the NIC be updated with the latest available management firmware version to get latest feature set.
90 Management Firmware and Firmware Upgrade Utility for Cavium FastLinQ(r) branded adapters can be downloaded from
91 `Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
92 For downloading Firmware Upgrade Utility, select NIC category, model and Linux distro.
93 To update the management firmware, refer to the instructions in the Firmware Upgrade Utility Readme document.
94 For OEM branded adapters please follow the instruction provided by the OEM to update the Management Firmware on the NIC.
96 - SR-IOV requires Linux PF driver version **8.20.x.x** or higher.
97 If the required PF driver is not available then download it from
98 `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
99 For downloading PF driver, select adapter category, model and Linux distro.
104 - For better performance, it is recommended to use 4K or higher RX/TX rings.
109 The following option can be modified in the ``config/rte_config.h`` file.
111 - ``RTE_LIBRTE_QEDE_FW`` (default **""**)
113 Gives absolute path of firmware file.
114 ``Eg: "/lib/firmware/qed/qed_init_values-8.40.33.0.bin"``
115 Empty string indicates driver will pick up the firmware file
116 from the default location /lib/firmware/qed.
117 CAUTION this option is more for custom firmware, it is not
118 recommended for use under normal condition.
120 The following options can be enabled with Meson flags.
122 - ``RTE_LIBRTE_QEDE_DEBUG_TX`` (default **disabled**)
124 Toggle display of transmit fast path run-time messages.
126 - ``RTE_LIBRTE_QEDE_DEBUG_RX`` (default **disabled**)
128 Toggle display of receive fast path run-time messages.
133 When there are multiple adapters and/or large number of Rx/Tx queues
134 configured on the adapters, the default (2560) number of memzone
135 descriptors may not be enough. Please increase the number of memzone
136 descriptors to a higher number as needed. When sufficient number of
137 memzone descriptors are not configured, user can potentially run into
140 .. code-block:: console
142 EAL: memzone_reserve_aligned_thread_unsafe(): No more room in config

188 SR-IOV: Prerequisites and Sample Application Notes
189 --------------------------------------------------
191 This section provides instructions to configure SR-IOV with Linux OS.
193 **Note**: librte_net_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 8.20.x.x or higher.
195 #. Verify SR-IOV and ARI capability is enabled on the adapter using ``lspci``:
197 .. code-block:: console
203 .. code-block:: console
206 Capabilities: [1b8 v1] Alternative Routing-ID Interpretation (ARI)
208 Capabilities: [1c0 v1] Single Root I/O Virtualization (SR-IOV)
210 Kernel driver in use: igb_uio
212 #. Load the kernel module:
214 .. code-block:: console
220 .. code-block:: console
222 systemd-udevd[4848]: renamed network interface eth0 to ens5f0
223 systemd-udevd[4848]: renamed network interface eth1 to ens5f1
225 #. Bring up the PF ports:
227 .. code-block:: console
232 #. Create VF device(s):
234 Echo the number of VFs to be created into ``"sriov_numvfs"`` sysfs entry
239 .. code-block:: console
241 echo 2 > /sys/devices/pci0000:00/0000:00:03.0/0000:81:00.0/sriov_numvfs
244 #. Assign VF MAC address:
246 Assign MAC address to the VF using iproute2 utility. The syntax is::
248 ip link set <PF iface> vf <VF id> mac <macaddr>
252 .. code-block:: console
254 ip link set ens5f0 vf 0 mac 52:54:00:2f:9d:e8
259 The VF devices may be passed through to the guest VM using ``virt-manager`` or
260 ``virsh``. QEDE PMD should be used to bind the VF devices in the guest VM
261 using the instructions from Driver compilation and testing section above.
265 (Supply ``--log-level="pmd.net.qede.driver:info`` to view informational messages):
267 Refer to the document
268 :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>` to run
269 ``testpmd`` application.
