I had a brief look at this today an the second commit won't apply
cleanly. I suspect we will open a can of worms here, so if you feel
strong about having that support in the 6.12.y series can you please
apporach upstream and ask for inclusion?
While the second is almost "trivial" change per se, it depends for
instance on b299ea006928 ("r8169: adjust version numbering for
RTL8126") which changes around the version numberings already.
Upstream will usually want a clean series of commits to apply, this
preferred to manual backport of patches.
I will close this bug with the first version including both commits.
In case at a later stage the 6.12.y series upstream will include the
support we will automatically pick them up as well.
Thanks for your understanding so far,
Regards,
Salvatore
