I assume this should go to net-next. You should mention the target tree
like [PATCH net-next 0/3] and so on, in this case it's pretty obvious
though.

Generally the series looks fine and I'm glad you factored-out common
parts like the LED handling which is a great improvement also for the
older PHYs found in MT7530 and MT7531 as well as MT7621 and MT7623N.

Splitting the the 3rd patch into more atomic changes would make
reviewing a bit easier.

Also note that I've recently submitted some fixes for the LED support
which now have already been accepted to the net tree, see

https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=5b5f724b05c550e10693a53a81cadca901aefd16

So it might be the best to wait for the next round of rebase of net-next
before dealing with your suggested changes to spare maintainers from
having to deal with the merge conflicts otherwise.

Generally it'd also be nice to add support for the NO_LINK rule to the
netdev trigger, as it is supported by the hardware, but that can also be
done later obviously.


Cheers


Daniel
