[PATCH net-next v2 00/26] switchdev: spring cleanup

[sfeldma@gmail.com]

From: Scott Feldman <sfeldma@gmail.com>

v2:

Address review comments:

 - [Jiri] squash a few related patches
 - [Roopa] don't remove NETIF_F_HW_SWITCH_OFFLOAD
 - [Roopa] address VLAN setlink/dellink
 - [Ronen] print warning is attr set revert fails

Not address:

 - Using something other than "swdev_" prefix
 - Vendor extentions

The patch set grew a bit to not only support port attr get/set but also add
support for port obj add/del.  Example of port objs are VLAN, FDB entries, and
FIB entries.  The VLAN support now allows the swdev driver to get VLAN ranges
and flags like PVID and "untagged".  Sridhar will be adding FDB obj support
in follow-on patch.


v1:

The main theme of this patch set is to cleanup swdev in preparation for
new features or fixes to be added soon.  We have a pretty good idea now how
to handle stacked drivers in swdev, but there where some loose ends.  For
example, if a set failed in the middle of walking the lower devs, we would
leave the system in an undefined state...there was no way to recover back to
the previous state.  Speaking of sets, also recognize a pattern that most
swdev API accesses are gets or sets of port attributes, so go ahead and make
port attr get/set the central swdev API, and convert everything that is
set-ish/get-ish to this new API.

Features/fixes that should follow from this cleanup:

 - solve the duplicate pkt forwarding issue
 - get/set bridge attrs, like ageing_time, from/to device
 - get/set more bridge port attrs from/to device

There are some rename cleanups tagging along at the end, to give swdev
consistent naming.

And finally, some much needed updates to the switchdev.txt documentation to
hopefully capture the state-of-the-art of swdev.  Hopefully, we can do a better
job keeping this document up-to-date.

Tested with rocker, of course, to make sure nothing functional broke.  There
are a couple minor tweaks to DSA code for getting switch ID and setting STP
updates to use new API, but not expecting amy breakage there.
