Overview | |||||
======== | |||||
Adapters based on the Intel(R) Ethernet Controller 800 Series require a Dynamic | |||||
Device Personalization (DDP) package file to enable advanced features (such as | |||||
dynamic tunneling, 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. 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. See "Safe Mode"!later in this | |||||
README!for more information. | |||||
A general purpose, OS-default DDP package is automatically installed with all | |||||
supported Intel Ethernet Controller 800 Series drivers on Microsoft* Windows*, | |||||
ESX*, FreeBSD*, and Linux* operating systems. Additional DDP packages are | |||||
available to address needs for specific market segments. For example, a | |||||
telecommunications (Comms) DDP package is available to support certain | |||||
market-specific protocols in addition to the protocols in the OS-default | |||||
package. | |||||
The OS-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 | |||||
Safe Mode | |||||
========= | |||||
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. | |||||
See the Intel(R) Ethernet Adapters and Devices User Guide for more details on | |||||
DDP!and Safe Mode. | |||||
Notes | |||||
===== | |||||
- 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. | |||||
- Except for Linux, you can only use one DDP package per driver, even if you | |||||
have more than one device installed that uses the driver. | |||||
- Only the first loaded PF per device can download a package for that device. | |||||
- If you are using DPDK, see the DPDK documentation at https://www.dpdk.org/ | |||||
for installation instructions and more information. | |||||
Installation and Troubleshooting | |||||
================================ | |||||
Microsoft* Windows* | |||||
------------------- | |||||
The DDP package is installed as part of the driver binary. You don't need to | |||||
take additional steps to install the DDP package file. | |||||
If you encounter issues with the DDP package file, download the latest driver. | |||||

--- | |||||
The DDP package is installed as part of the driver binary. You don't need to | |||||
take additional steps to install the DDP package file. | |||||
If you encounter issues with the DDP package file, download the latest driver. | |||||
FreeBSD | |||||
------- | |||||
The FreeBSD driver automatically installs the default DDP package file during | |||||
driver installation. See the ice driver README for general installation and | |||||
building instructions. | |||||
The DDP package loads during device initialization. The driver looks for the | |||||
ice_ddp module and checks that it contains a valid DDP package file. | |||||
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. | |||||
NOTE: It's important to do 'make install' during initial ice driver | |||||
installation so that the driver loads the DDP package automatically. | |||||
Linux | |||||
----- | |||||
The Linux driver automatically installs the default DDP package file during | |||||
driver installation. See the ice driver README for general installation and | |||||
building instructions. | |||||
The DDP package loads during device initialization. The driver looks for | |||||
intel/ice/ddp/ice.pkg in your firmware root (typically /lib/firmware/ or | |||||
/lib/firmware/updates/) and checks that it contains a valid DDP package file. | |||||
The ice.pkg file is a symbolic link to the default DDP package file installed | |||||
by the linux-firmware software package or the ice out-of-tree driver | |||||
installation. | |||||
If you encounter issues with the DDP package file, you may need to download an | |||||
updated driver or DDP package file. See the log messages for more information. | |||||
You can install specific DDP package files for different physical devices in | |||||
the same system. To install a specific DDP package: | |||||
1. Download the DDP package file (ice-x.x.x.x.zip) you want for your device. In | |||||
addition to licensing information and this README, this zip file contains the | |||||
following files: | |||||
ice-x.x.x.x.pkg | |||||
ice.pkg | |||||
NOTE: The ice.pkg file is a Linux symbolic link file pointing to | |||||
ice-x.x.x.x.pkg (in the same path). | |||||
2. Rename the ice-x.x.x.x.pkg file as ice-xxxxxxxxxxxxxxxx.pkg, where | |||||
'xxxxxxxxxxxxxxxx' is the unique 64-bit PCI Express device serial number (in | |||||
hex) of the device you want the package downloaded on. The filename must | |||||
include the complete serial number (including leading zeros) and be all | |||||
lowercase. For example, if the 64-bit serial number is b887a3ffffca0568, then | |||||
the file name would be ice-b887a3ffffca0568.pkg. | |||||
To find the serial number from the PCI bus address, you can use the following | |||||
command: | |||||
# lspci -vv -s af:00.0 | grep -i Serial | |||||
Capabilities: [150 v1] Device Serial Number b8-87-a3-ff-ff-ca-05-68 | |||||
You can use the following command to format the serial number without the | |||||
dashes: | |||||
# lspci -vv -s af:00.0 | grep -i Serial | awk '{print $7}' | sed s/-//g | |||||
b887a3ffffca0568 | |||||
3. Copy the renamed DDP package file to /lib/firmware/updates/intel/ice/ddp/. | |||||
If the directory does not yet exist, create it before copying the file. | |||||
4. Unload all of the PFs on the device. | |||||
5. Reload the driver with the new package. | |||||
NOTE: The presence of a device-specific DDP package file overrides the loading | |||||
of the default DDP package file (ice.pkg). | |||||
