Danielle Ratson 89a7f155e6 bridge: switchdev: Notify about VLAN protocol changes ...

[ Upstream commit 22ec19f3aee327806c37c9fa1188741574bc6445 ]

Drivers that support bridge offload need to be notified about changes to
the bridge's VLAN protocol so that they could react accordingly and
potentially veto the change.

Add a new switchdev attribute to communicate the change to drivers.
