Write a release note for Tech Preview XDP features in RHEL 8.3
The RN is now available on the Customer Portal:
Update for RHEL 8.4:
For XDP, we're now supporting also the redirect and tx verdicts. Meaning the sentence "The XDP_TX and XDP_REDIRECT return codes." should be removed from the Technology Previews / Networking chapter.
The "XDP is conditionally supported" section in New Features / Networking sections should be adjusted. I propose the following wording:
With this release, the XDP_TX and XDP_REDIRECT return codes are now supported in XDP programs.
Red Hat supports the eXpress Data Path (XDP) feature only if all of the following conditions apply:
* You load the XDP program on an AMD or Intel 64-bit architecture
* You use the libxdp library to load the program into the kernel
* The XDP program does not use the XDP hardware offloading
For details about unsupported XDP features, see Overview of XDP features that are available as Technology Preview.
Longer term, we'll need to find a better place for the support conditions. The libxdp condition is going to stay for the RHEL 8 lifetime and having this in the New Features forever does not look correct.
For some reason, the 8.3 release notes contain two sections in the Technology Previews / Networking chapter: "XDP available as a Technology Preview" and "XDP features that are available as Technology Preview". These should be merged.

I merged the RN from this BZ and BZ#1503672.
The merged RN is now here in this BZ (see DocText field)
To track the "what-is-supported-in-8.4" part of XDP, I created BZ#1952421 for the corresponding RN.
