Merge branch 'swdev_ops'
Scott Feldman says:
====================
switchdev: add swdev ops
v3:
- Fix missing include for DSA build
v2:
- Per Simon's review, squash some of the dependent commits into one to
make series git bisect safe.
v1:
Per discussions at netconf, move switchdev ndo ops to a new swdev_ops to
keep ndo namespace clean and maintain switchdev-related ops into one place.
There are no functional changes here; just shuffling ops around for better
organization.
====================
