Description Gurpreet Singh 2023-06-26 22:05:47 UTC

Description of problem:

The VFLAG implementation used to implement LACP | mode=4 bond for the OVS Hardware Offload | Nvidia solution does not provide a way to select a specific xmit hash policy. The customer is Verizon and requires a way to implement a VFLAG with xmit hash policy layer3+4

The feature support was added in RHEL 8.6 and is available in RHEL 9.2 as well. 

This requirement is to validate/test the functionality in OSP for GA support. The feature is available as TP in OSP 17.1




This Jira is opened to build, and validate this feature end-to-end in RHOSP.
