QEDE Poll Mode Driver
======================
- N-tuple filter and flow director (limited support)
- NPAR (NIC Partitioning)
- SR-IOV VF
-- VXLAN tunneling offload
-- MPLSoUDP Tx tunnel offload
+- GRE Tunneling offload
+- GENEVE Tunneling offload
+- VXLAN Tunneling offload
+- MPLSoUDP Tx Tunneling offload
Non-supported Features

- SR-IOV PF
-- GENEVE and NVGRE Tunneling offloads

+Co-existence considerations
+---------------------------
+- QLogic FastLinQ QL4xxxx CNAs can have both NIC and Storage personalities. However, coexistence with storage protocol drivers (qedi and qedf) is not supported on the same adapter. So storage personality has to be disabled on that adapter when used in DPDK applications.
+- For SR-IOV case, qede PMD will be used to bind to SR-IOV VF device and Linux native kernel driver (qede) will be attached to SR-IOV PF.
Supported QLogic Adapters
-------------------------
Prerequisites
-------------
-- Requires storm firmware version **8.30.12.0**. Firmware may be available
+- Requires storm firmware version **8.33.12.0**. Firmware may be available
inbox in certain newer Linux distros under the standard directory
- ``E.g. /lib/firmware/qed/qed_init_values-8.30.12.0.bin``
+ ``E.g. /lib/firmware/qed/qed_init_values-8.33.12.0.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.
+ `linux-firmware git repository <http://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qed>`_
+ or `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
+ To download firmware file from QLogic website, select adapter category, model and DPDK Poll Mode Driver.
+
+- 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
