Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Validate NIX maximum LFs correctly NIX maximum number of LFs can be set via devlink command but that can be done before assigning any LFs to a PF/VF. The condition used to check whether any LFs are assigned is incorrect. This patch fixes that condition.
