Hi all,

I noticed today the series state is 'Awaiting Upstream'. I am wondering if
this series is expected to go through a different tree, e.g. wireless one
(adding Kalle in cc). In this particular case the series changes only
the mtk ethernet driver and mt76 is built since we modify a common include (but
there are no changes in mt76). My personal opinion is this series is suited to
go through net-next tree but I would be fine even if it goes through Kalle's
one. Any opinions?

Regards,
Lorenzo
