What is Dynamic Device Personalization (DDP)?1
Loadable Packet Classifications (Parser) personalization
for any well-defined traffic profiles for VNFs or
appliances with a specific position in the network
 Enable new protocols:
– GTP tunnel support, GTP-C and GTP-U as a separate flow types
– IP protocols as new flow types, for example L2TPv3, ESP/AH for IPSec
– Legacy protocols: PPPoE, PPPoL2TPv2
 Modify existing protocols:
– VXLAN with IP payload, NSHoUDP
– New PTYPEs on RX descriptor: for example, IPv4 TCP in one/two
MPLS label(s)
 Make Smart NIC act Stupid:
– Disable GRE classification
– Disable IPv4 classification
 Debug:
– Read configuration/statistics registers in one admin command call
Configurable tunnel filters for traffic steering
(Classifier Switch)
 Steering packets to a VM on QinQ
 Steering packets to a VM on Tunnel ID
(VXLAN, NVGRE, MPLS, GTP, NSH*)
 User definable steering/mirroring rules

3. Create binary package file to be applied to FVL by customer
4. Download profile to FVL to change Parser configuration: new
PCTYPEs, PTYPEs, Protocols, extracted fields.
Profile is not persistent, on reset the original configuration is restores from
the NVM. SW can restore original configuration without reset as profiles
support “roll-back” transaction.

Dynamic Device Personalization Summary
Dynamic Device Personalization can be used on any OS supported by DPDK
 For example, QUIC protocol classification on both Windows and Linux Oses
Dynamic Device Personalization allows a DPDK application to enable identification of
new protocols, for example, GTP, PPPoE, QUIC, MPLSoGRE, SRv6, etc without requiring a
reboot due to changing hardware or firmware updates.
Allows for existing Parse Graphs to be modified to support new usage models as they
are defined enabling faster time to market for DPDK enable applications.

RSS
RSS
PPPoE is unknown flow type, so no RSS, FDIR or other filters are possible on inner packet fields.
FVL classifies PPPoE (Discovery and Session) packets as L2 payload.
With a DDP profile, PPPoE header can be parsed and encapsulated packet classified.
For example, for PPPoE session with UDP in IPv4, as shown above, RSS and FDIR filters can be used on UDP.
If required, RSS, FDIR and Tunnel filters can use PPPoE Session ID as well.

MPLSoGRE is unknown flow type, so no RSS, FDIR or other filters are possible. Packet type set to 43.
With MPLSoGRE flow type is defined by encapsulated frame, for example, UDP in IPv4 as shown above
so all filters available for UDP can be applied to the packets: RSS, FDIR. Packet type 59-72.
RSS, FDIR and Tunnel filters can use MPLS label as tunnel (tenant) ID.

28. Ethernet Networking Division
Q&A, generic
Q How profiles will be distributed?
A
There a two main ways of distributing profiles:
1. as a separate binary file and loaded by application
2. it can be precompiled to a driver, and selected on device initialization stage
For the trials/test with a customer we use the first option, as profile configuration can change
during pre-release.
After full validation, release version can be precompiled with a driver (kernel or DPDK) or an
application to be selected at initialization.
Q Can profile be applied to only one port/PF/VF of a multi-port device?
A
No, profiles affect all port on a device. In virtual environment not only PFs but all VFs will be
affected as well. Which PF is used to apply a profile does not matter.
Q Do we need to reload a profile after NIC reset or, once loaded, profile stays in the NVM?
A Profiles are not persistent, so must be reloaded after any reset of the NIC.
Q
Can we use profiles on any other i40e compatible devices, for example, on Intel® Ethernet
Connection X722 ports of Intel® Chipset C620?
A No, the Intel Ethernet Connection X722 does not support profiles.
28

29. Ethernet Networking Division
Q&A, generic
Q Does firmware version 5 supports dynamic device personalization profiles?
A No, dynamic device personalization will be available starting from firmware version 6
Q How many profiles can be loaded simultaneously on one device?
A
Thou the Network Adapters can provide information about up to 16 loaded profiles. Multiple
profiles are not recommended. In case if, for some reason, multiple profiles are needed, it
should be treated very carefully to make sure that profiles are not overlapping and to avoid
any unexpected behaviour.
Q Will I (as a customer) be able to create profiles by myself?
A
No, profile programming requires very deep knowledge of the device internals and can be
done only by Intel engineers.
Q Can I apply profile while traffic is running through the device or I have to stop device first?
A You can apply/remove profile with traffic running, but some packet loss should be expected.
