#1583510 — [PATCH net-next v2 5/6] net: dsa: mv88e6xxx: add VTU ops

FromVivien Didelot <vivien.didelot@savoirfairelinux.com>

Subject[PATCH net-next v2 5/6] net: dsa: mv88e6xxx: add VTU ops
Message-ID<tbSky-5TK-27@gated-at.bofh.it>
Because there are several variant of the VTU operations and because
checking for the presence of an STU is not enough, add new ops to the
info structure to describe the VTU operations that a chip supports.

You appear to be taking out code you just added in the previous patch.

Please think about structuring these patches different. We want these
ops, but i don't think you have the best way of getting there.
