br_switchdev_port_vlan_add() currently emits a SWITCHDEV_PORT_OBJ_ADD event with a SWITCHDEV_OBJ_ID_PORT_VLAN for 2 distinct cases: - a struct net_bridge_vlan got created - an existing struct net_bridge_vlan was modified This makes it impossible for switchdev drivers to properly balance PORT_OBJ_ADD with PORT_OBJ_DEL events, so if we want to allow that to happen, we must provide a way for drivers to distinguish between a VLAN with changed flags and a new one. Annotate struct switchdev_obj_port_vlan with a "bool changed" that distinguishes the 2 cases above. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
