[PATCH net-next v2 0/3] switchdev: add swdev ops

[sfeldma]

From: Scott Feldman <sfeldma@gmail.com>

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.

Scott Feldman (3):
  switchdev: add swdev ops
  switchdev: use new swdev ops
  netdev: remove ndo ops for switchdev

[PATCH net-next v2 1/3] switchdev: add swdev ops

[sfeldma]

From: Scott Feldman <sfeldma@gmail.com>

As discussed at netconf, introduce swdev_ops as first step to move switchdev
ops from ndo to swdev.  This will keep switchdev from cluttering up ndo ops
space.

This isn't correct kernel-doc syntax.

It was a cut-and-paste from netdevice.h.  Give me an example of
correct syntax, and I'll fix these.
