sys: replace comma with semicolon when pertinent.

Uses of commas instead of a semicolons can easily go undetected. The comma
can serve as a statement separator but this shouldn't be abused when
statements are meant to be standalone.

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

Similar to the (1 << 31) case it is not defined to do (2 << 30).

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

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

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

Fix the arswitch instability problem. It turns out that the

2013-07-23T14:02:38+00:00

arswitch_writereg() routine was writing the registers in the wrong order.

Revert -r241918 as the root problem is now fixed. Remove another workaround
from arswitch_ar7240.c.

Simplify and fix the code on arswitch_writephy() by using
arswitch_writereg().

While here remove a redundant declaration from arswitchvar.h.

Add a new flag (ETHERSWITCH_VID_VALID) to say what vlangroups are in use.

2013-07-23T13:56:38+00:00

This fix the case when etherswitch is printing the information of port 0
vlan group (in port based vlan mode) with no member ports.

Add the ETHERSWITCH_VID_VALID support to ip17x driver.

Add the ETHERSWITCH_VID_VALID support to rt8366 driver.

arswitch doesn't need to be updated as it doesn't support vlans management
yet.

Bring in a basic ethernet switch driver for the IP17x series of

2013-05-08T20:58:41+00:00

switches.

These are notably found on some AR71xx based Mikrotik boards.

Fix the ukswitch code to work with the new vlan changes:

2013-05-08T20:56:43+00:00

* Fix API changes;
* remove unused code;
* Allow some switches to be used that don't expose a set of PHY
  registers for the CPU facing port (eg the ADM6996 for the Ubiquiti
  Routerstation.)

Add the ability to change the vlan operation mode.

2013-05-08T20:46:54+00:00

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.).
