[etherswitch] add the first pass of a simple API to flush and fetch the L2 address table from the ethernet switch.

This stuff may be a bit fluid during this -HEAD cycle as various other
switch features are added, but the current stuff is enough to drive
initial development and features on the atheros range of integrated
and external switches.

* add a method to flush the whole address table;
* add a method to flush all addresses on a given port;
* add a method to download the address table;
* .. and then a method to fetch entries from the address table.

The table fetch/read methods pass through to the drivers for now since
the drivers may implement different ways of fetching/caching the address
table data. The atheros devices for example fetch the table by
iterating over the table through a set of registers and so you need
to keep that locked whilst you iterate otherwise you may have the table
flushed half way by a port status change.

This is a no-op until the userland and arswitch code shows up.

sys/dev: further adoption of SPDX licensing ID tags.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Add the ability to change the vlan operation mode.

This adds a vlan capability field to etherswitch_info structure and some
definitions of ports flags.

It adds the support to global config parameters which right now is used
only to switch between the vlan modes, but it is intended to be extended
to support the setup of others parameters (STP, mirror, etc.).
