Jeff was out sick last week. It might take him a bit to catch up.

I'll remind him when I see him next (which I hope is soon).

Pavel, before ask for revert - let's check Benjamin's patch following to his previous patch. Previous patch was not competed and latest one come to complete changes.

v4.15-rc4+:

Ethernet works with 19110cfbb reverted.

Ethernet works With patchwork.ozlabs.org/patch/846825/ applied.

Hmm. So... ethernet originally did not work with patch/846825/ applied
or 19110cfbb reverted, so I re-plugged ethernet cables. Now it works
even with plain v4.15-rc4+.

So it looks like the bug was fixed in the mainline in the meantime...?

Sorry for the noise,
Pavel

Good Pavel, thanks for update us, let's keep both patch applied and see
ethernet adapter behavior.
