The QEDE poll mode driver library (**librte_pmd_qede**) implements support
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
-several standard Linux distros like RHEL7.x, SLES12.x and Ubuntu.
+several standard Linux distros like RHEL, SLES, Ubuntu etc.
It is compile-tested under FreeBSD OS.

+Co-existence considerations
+---------------------------
+
+- QLogic FastLinQ QL4xxxx CNAs support Ethernet, RDMA, iSCSI and FCoE
+ functionalities. These functionalities are supported using
+ QLogic Linux kernel drivers qed, qede, qedr, qedi and qedf. DPDK is
+ supported on these adapters using qede PMD.
+
+- When SR-IOV is not enabled on the adapter,
+ QLogic Linux kernel drivers (qed, qede, qedr, qedi and qedf) and qede
+ PMD can’t be attached to different PFs on a given QLogic FastLinQ
+ QL4xxx adapter.
+ A given adapter needs to be completely used by DPDK or Linux drivers
+ Before binding DPDK driver to one or more PFs on the adapter,
+ please make sure to unbind Linux drivers from all PFs of the adapter.
+ If there are multiple adapters on the system, one or more adapters
+ can be used by DPDK driver completely and other adapters can be used
+ by Linux drivers completely.
+
+- When SR-IOV is enabled on the adapter,
+ Linux kernel drivers (qed, qede, qedr, qedi and qedf) can be bound
+ to the PFs of a given adapter and either qede PMD or Linux drivers
+ (qed and qede) can be bound to the VFs of the adapter.
+
+- For sharing an adapter between DPDK and Linux drivers, SRIOV needs
+ to be enabled. Bind all the PFs to Linux Drivers(qed/qede). Create
+ a VF on PFs where DPDK is desired and bind these VFs to qede_pmd.
+ Binding of PFs simultaneously to DPDK and Linux drivers on a given
+ adapter is not supported.
Supported QLogic Adapters
-------------------------
Prerequisites
-------------
-- Requires storm firmware version **8.30.12.0**. Firmware may be available
+- Requires storm firmware version **8.40.33.0**. Firmware may be available
inbox in certain newer Linux distros under the standard directory
- ``E.g. /lib/firmware/qed/qed_init_values-8.30.12.0.bin``
+ ``E.g. /lib/firmware/qed/qed_init_values-8.40.33.0.bin``.
If the required firmware files are not available then download it from
- `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
- For downloading firmware file, select adapter category, model and DPDK Poll Mode Driver.
+ `linux-firmware git repository <http://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qed>`_.
-- Requires management firmware (MFW) version **8.30.x.x** or higher to be
- flashed on to the adapter. If the required management firmware is not
- available then download from
- `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
- For downloading firmware upgrade utility, select adapter category, model and Linux distro.
- To flash the management firmware refer to the instructions in the QLogic Firmware Upgrade Utility Readme document.
+- Requires the NIC be updated minimally with **8.30.x.x** Management firmware(MFW) version supported for that NIC.
+ It is highly recommended that the NIC be updated with the latest available management firmware version to get latest feature set.
+ Management Firmware and Firmware Upgrade Utility for Cavium FastLinQ(r) branded adapters can be downloaded from
+ `Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
+ For downloading Firmware Upgrade Utility, select NIC category, model and Linux distro.
+ To update the management firmware, refer to the instructions in the Firmware Upgrade Utility Readme document.
+ For OEM branded adapters please follow the instruction provided by the OEM to update the Management Firmware on the NIC.
- SR-IOV requires Linux PF driver version **8.20.x.x** or higher.
If the required PF driver is not available then download it from
`QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
For downloading PF driver, select adapter category, model and Linux distro.

recommended for use under normal condition.
+Config notes
+~~~~~~~~~~~~
+
+When there are multiple adapters and/or large number of Rx/Tx queues
+configured on the adapters, the default (2560) number of memzone
+descriptors may not be enough. Please increase the number of memzone
+descriptors to a higher number as needed. When sufficient number of
+memzone descriptors are not configured, user can potentially run into
+following error.

SR-IOV: Prerequisites and Sample Application Notes
--------------------------------------------------
This section provides instructions to configure SR-IOV with Linux OS.
-**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.
