Hi all,

This patch series splits the removal of the switchdev_ops that was
proposed a few times before and first tackles the easy part which is the
removal of the single call to switchdev_port_attr_get() within the
bridge code.

As suggestd by Ido, this patch series adds a
SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS which is used in the same
context as the caller of switchdev_port_attr_set(), so not deferred, and
then the operation is carried out in deferred context with setting a
support bridge port flag.

Follow-up patches will do the switchdev_ops removal after introducing
the proper helpers for the switchdev blocking notifier to work across
stacked devices (unlike the previous submissions).

David this does depend on Russell's "[PATCH net-next v5 0/3] net: dsa:
mv88e6xxx: fix IPv6".

Changes in v3:

- rebased against net-next/master after Russell's IPv6 changes to DSA
- ignore prepare/commit phase for PRE_BRIDGE_FLAGS since we don't
  want to trigger the WARN() in net/switchdev/switchdev.c in the commit
  phase

Changes in v2:

- differentiate callers not supporting switchdev_port_attr_set() from
  the driver not being able to support specific bridge flags

- pass "mask" instead of "flags" for the PRE_BRIDGE_FLAGS check

- skip prepare phase for PRE_BRIDGE_FLAGS

- corrected documentation a bit more

- tested bridge_vlan_aware.sh with veth/VRF
