Thank you for highlighting this.

Vladimir told me recently over the phylink get_interfaces vs get_caps
change for DSA, and I quote:

  David who applied your patch can correct me, but my understanding from
  the little time I've spent on netdev is that dead code isn't a candidate
  for getting accepted into the tree, even more so in the last few days
  before the merge window, from where it got into v5.16-rc1.
  ...
  So yes, I take issue with that as a matter of principle, I very much
  expect that a kernel developer of your experience does not set a
  precedent and a pretext for people who submit various shady stuff to the
  kernel just to make their downstream life easier.

This sounds very much like double-standards, especially as Vladimir
reviewed this.

I'm not going to be spiteful NAK these patches, because we all need to
get along with each other. I realise that it is sometimes useful to get
code merged that facilitates or aids further development - provided
that development is submitted in a timely manner.
