spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+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.

[arswitch] begin tidying up the learning and ATU management, introduce ATU APIs.

2018-02-02T22:05:36+00:00

* Refactor the initial learning configuration (port learning, address expiry,
  handling address moving between ports, etc, etc) into a separate HAL routine
* and ensure that it's consistent between switch chips - the AR8216,8316,724x,9331
  SoCs all share the same switch code.
* .. the AR8327 needs doing - the defaults seem OK for now
* .. the AR9340 is different but it's also programmed now.

* Add support for flushing a single port worth of ATU entries
* Add support for fetching the ATU table from AR8216 and derived chips

Tested:

* AR9344, Carambola 2

TODO:

* Further testing on other chips
* Add AR9340 support
* Add AR8327 support

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.

arswitch: Ensure the lock is always held when calling arswitch_modifyreg()

2017-01-15T10:21:25+00:00

arswitch_setled() and a number of _global_setup functions did not acquire the
lock before calling arswitch_modifyreg(). With WITNESS enabled this would
instantly panic.

Discovered on a TPLink-3600:
("panic: mutex arswitch not owned at sys/dev/etherswitch/arswitch/arswitch_reg.c:236")

Update my TODO items.

[mdio] migrate mdiobus out of etherswitch and into a top-level device of its own.

2015-12-26T02:31:39+00:00

The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.

Revert r268543.

We should probably fix sys/gpio.h instead.

Move iic.h to sys/ so that it's automatically installed in /usr/include/sys.

2014-07-12T01:04:10+00:00

This lets us call iic(4) ioctls without needing the kernel source code
and follows the same model of GPIO.

Add the support for 802.1q and port based vlans for arswitch.

2013-07-23T14:24:22+00:00

Tested on: RB450G (standalone ar8316), RSPRO (standalone ar8316) and
TPLink MR-3220 (ar724x integrated switch).
