mlxsw: Support VLAN devices in mirroring offloads

Petr says:

When offloading "tc action mirred mirror", there are several scenarios
where VLAN devices can show up, that mlxsw can offload on Spectrum
machines.

I) A direct mirror to a VLAN device on top of a front-panel port device
   (commonly referred to as "RSPAN")

II) VLAN device in egress path of a packet when resolving a mirror to
    gretap or ip6gretap netdevice.

Specifically in the latter case, the following are the cases that can be
offloaded:

IIa) VLAN device directly above a physical device.
IIb) A VLAN-unaware bridge where the egress device is as in IIa.
IIc) VLAN device on top of a VLAN-aware bridge where the egress device
     is a physical device.

This patch set implements all the above cases.

First, in patch #1, br_vlan_get_info() is extended to allow bridge
master argument.

Case I is then implemented in patches #2 and #3, case II in patch #4.

Note that handling of VLAN protocol is not included. In case I, mirrored
packets may end up being double-tagged, and it might be reasonable for
the outer tag to be an 802.1ad. However, the protocol type configuration
would have to be put on the same VLAN netdevice that represents normal
VLAN traffic, and mlxsw currently ignores this setting in that case. Thus
this support was left out and the encapsulation always uses 802.1q
protocol.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
