Overview
========
Devices based on the Intel(R) Ethernet 800 Series require a Dynamic
Device Personalization (DDP) package file to enable advanced features
(such as dynamic tunneling, Intel(R) Ethernet Flow Director, RSS, and
ADQ).
DDP allows you to change the packet processing pipeline of a device by
applying a profile package to the device at runtime. Profiles can be
used to, for example, add support for new protocols, change existing
protocols, or change default settings. DDP profiles can also be rolled
back without rebooting the system.
The DDP package loads during device initialization or driver runtime,
depending on the operating system. The driver checks to see if the DDP
package is present and compatible. If this file exists, the driver
will load it into the device. If the DDP package file is missing or
incompatible with the driver, the driver will go into Safe Mode where
it will use the configuration contained in the device's NVM.
Safe Mode disables advanced and performance features, and supports
only basic traffic and minimal functionality, such as updating the NVM
or downloading a new driver or DDP package.
Refer to the Intel(R) Ethernet Adapters and Devices User Guide for
more details on DDP and Safe Mode.
A general-purpose, default DDP package is automatically installed with
all supported Intel Ethernet 800 Series drivers on supported operating
systems. Additional DDP packages are available to address needs for
specific market segments or targeted solutions.
The default DDP package supports the following:
* MAC
* EtherType
* VLAN
* IPv4
* IPv6
* TCP
* ARP
* UDP
* SCTP
* ICMP
* ICMPv6
* CTRL
* LLDP
* VXLAN-GPE
* VXLAN (non-GPE)
* Geneve
* GRE
* NVGRE
* RoCEv2
* MPLS (up to 5 consecutive MPLS labels in the outermost Layer 2
header group)
Supported Operating Systems

Notes
=====
* In Linux, FreeBSD, and Windows, you cannot update the DDP package if
any PF drivers are already loaded. To overwrite a package, unload
all PFs and then reload the driver with the new package.
* In FreeBSD and Windows, you can only use one DDP package per driver,
even if you have more than one device installed that uses the
driver.
* In Linux, FreeBSD, and Windows, only the first loaded PF per device
can download a package for that device. In ESXi, you can load
different DDP packages for different PFs associated with a device.
* If you are using DPDK, see the DPDK documentation at
https://www.dpdk.org/ for installation instructions and more
information.
Troubleshooting
===============
FreeBSD
-------
If you encounter issues with the DDP package file, you may need to
download an updated driver or ice_ddp module. See the log messages for
more information.
