spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-07-25T15:13:49+00:00

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

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

2017-11-27T14:52:40+00:00

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.

Fix up support for the AR8327.

* Even though I got the registers around "right", it seems
  I'm not tickling the MDIO access correctly for the internal PHY
  bus.  Some of the switches are fine poking at the external PHY
  registers; others aren't.  So, enable direct PHY bus access
  for the AR8327, and leave the existing code in place for the
  others.

* Go and shuffle the register access around.  Whilst here,
  restore the 2ms delay if changing page.

* Comment out some of the stub printf()s; there's some upcoming
  work to add port VLAN support.

Tested:

* AP135 development board
* Carambola2 - AR9331 SoC

Commit the first pass of the etherswitch support.

This is designed to support the very basic ethernet switch chip behaviour,
specifically:

* accessing switch register space;
* accessing per-PHY registers (for switches that actually expose PHYs);
* basic vlan group support, which applies for the rtl8366 driver but not
  for the atheros switches.

This also includes initial support for:

* rtl8366rb support - which is a 10/100/1000 switch which supports
  vlan groups;
* Initial Atheros AR8316 switch support - which is a 10/100/1000 switch
  which supports an alternate vlan configuration (so the vlan group
  methods are stubbed.)

The general idea here is that the switch driver may speak to a variety of
backend busses (mdio, i2c, spi, whatever) and expose:

* If applicable, one or more MDIO busses which ethernet interfaces can
  then attach PHYs to via miiproxy/mdioproxy;

* exposes miibusses, one for each port at the moment, so ..

* .. a PHY can be exposed on each miibus, for each switch port, with all
  of the existing MII/ifnet framework.

However:

* The ifnet is manually created for now, and it isn't linked into the
  interface list, nor can you (currently) send/receive frames on this ifnet.
  At some point in the future there may be _some_ support for this, for
  switches with a multi-port, isolated mode.

* I'm still in the process of sorting out correct(er) locking.

TODO:

* ray's switch code in zrouter (zrouter.org) includes a much more developed
  newbus API that covers the various switch methods, as well as a
  capability API so drivers, the switch layer and the userland utility
  can properly control the subset of supported features.

  The plan is to sort that out later, once the rest of ray's switch drivers
  are brought over and extended to export MII busses and PHYs.
