The document details Intel's Ethernet 700 series, focusing on its capabilities, particularly Dynamic Device Personalization (DDP). It explains that DDP allows for real-time configuration and updates of packet classification to support emerging protocols, thereby enhancing performance in various network scenarios. Additionally, it reinforces that Intel disclaims all warranties regarding its products and encourages consulting other benchmarks for complete performance evaluation.

Intel® Ethernet 700 Series – Increased
Programmability
Dynamic Device
Personalization (DDP)Profiles for Intel® Ethernet 700 Series enables run-time updating and
configuration of parse graph to expand or modify protocol support
allowing early adoption of new technologies.
Example:
Default Tunnel protocol support does not cover all uses cases
• VXLAN, GENEVE, NVGRE, MPLS, VXLAN-GPE currently supported
Dynamic Device Personalization enables
• Loadable profiles for packet classification for additional or modification of existing
protocols such as MPLSoGRE, GTP-U/GTP-C, PPPoE, QUIC, ESP, AH
• Configurable tunnel filters for enhanced traffic steering

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
1Does not include Intel® Ethernet Connection X722

10. Ethernet Networking Division 10
DDP can be applied in Transaction like mode
No need to reset NIC to restore original configuration:
“Write Profile” AQ returns original values ready to be applied.
Profile can be applied/removed with traffic running*.
* some packet loss is expected during profile download/rollback

FVL6 with Personalization profile applied:

RSS
GTP-U is unknown flow type, so no RSS, FDIR or other filters are possible on encapsulated frame
GTP-U flow type is defined, encapsulated frame fields (including GTP TEID) can be used for RSS, FDIR.
Encapsulated frame type is indicated on RX descriptor, for example, TCP in GTP-U or GTP-U echo message
GTP-C flow type is defined as well and has separate RSS/FDIR configuration.

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.
