Subject: NVIDIA roadmap for 24.03
Please find below NVIDIA roadmap for 24.03 release:
A. rte_flow new APIs
=================
Adding a new action for header re-write of NAT64.
NAT64 (Network Address Translation 64) is a networking technology that facilitates communication between IPv6 and IPv4 networks.
Supporting IPv4 IHL & total length, IPv6 payload length and TCP data offset in the rte_flow modify field actions.
For example, by using the ADD operation, the length of the IP and TCP headers can be calculated. When it is equal to the total
length of an IP packet, it means that there is no encrypted header and the IPSec matching can be skipped.
Improve code to enable faster rule insertion/deletion.
Improve indexed pool management for faster allocations.
When doing ECMP (Equal-Cost Multipath Routing) in the underlay network with a tunnel encapsulation,
for example, GENEVE, the outer UDP source port can be used as an identifier.
The source port calculation in the slow path SW and data path HW offloading should be aligned to solve the path selection mismatch.
Adding new item RTE_FLOW_ITEM_TYPE_COMPARE to
compare 2 fields with reusing the MODIFY_FIELD
Provide a more flexible comparison.
Enable matching random inside a range. An enhancement of the random item
matching.
Used for sampling the packets.
The table size (maximal number of rules supported) is fixed when creating a template table and the ASO actions number is also fixed when
configuring the port.
Reduce the number of tables to be created. Using rehash mechanism to handle the table resize for this stage.
B. Net/mlx5 PMD updates
=====================
Different NIC generations has different matching size
limits (number of matching fields).
Once application receive such error, it should perform
relevant enhancements to build an
alternate matching pipe that fits to the NIC’s limits.
No ports number limitation when creating an indirect connection
tracking action in the template API.
Support
VXLAN-GPE
matching in template API, including the flag and reserved bits.
Added support for Geneve raw_encap/decap as
well as Geneve options modify with template API in addition to previously supported match on Geneve options.
C. Test apps updates
=================
For Connectx -7 Nic's that support 4 physical ports, detect port number, and update hairpin logic
to enable use of all ports.
Current testpmd enable sequential pair for hairpin, this feature is meant to enable any pair.
