net: bridge: vlan options: add support for tunnel mapping
In order to bring the new vlan API on par with the old one and be able
to completely migrate to the new one we need to support vlan tunnel mapping
and statistics. This patch-set takes care of the former by making it a
vlan option. There are two notable issues to deal with:
- vlan range to tunnel range mapping
* The tunnel ids are globally unique for the vlan code and a vlan can
be mapped to one tunnel, so the old API took care of ranges by
taking the starting tunnel id value and incrementally mapping
vlan id(i) -> tunnel id(i). This set takes the same approach and
uses one new attribute - BRIDGE_VLANDB_ENTRY_TUNNEL_ID. If used
with a vlan range then it's the starting tunnel id to map.
- tunnel mapping removal
* Since there are no reserved/special tunnel ids defined, we can't
encode mapping removal within the new attribute, in order to be
able to remove a mapping we add a vlan flag which makes the new
tunnel option remove the mapping
The rest is pretty straight-forward, in fact we directly re-use the old
code for manipulating tunnels by just mapping the command (set/del). In
order to be able to keep detecting vlan ranges we check that the current
vlan has a tunnel and it's extending the current vlan range end's tunnel
id.

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.
