The QEDE poll mode driver library (**librte_pmd_qede**) implements support
-for **QLogic FastLinQ QL4xxxx 10G/25G/40G/50G/100G CNA** family of adapters as well
-as their virtual functions (VF) in SR-IOV context. It is supported on
+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.
It is compile-tested under FreeBSD OS.

+- QLogic FastLinQ QL4xxxx 10G/25G/40G/50G/100G Intelligent Ethernet Adapters (IEA) and Converged Network Adapters (CNA)
Prerequisites
-------------
-- Requires firmware version **8.18.x.** and management firmware
- version **8.18.x or higher**. Firmware may be available
+- Requires storm firmware version **8.30.12.0**. Firmware may be available
inbox in certain newer Linux distros under the standard directory
- ``E.g. /lib/firmware/qed/qed_init_values-8.18.9.0.bin``
+ ``E.g. /lib/firmware/qed/qed_init_values-8.30.12.0.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.
+
+- 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.
+
+- 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.
-- If the required firmware files are not available then visit

Driver compilation and testing
------------------------------
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.
