It's still hardcoded (for db120) but it is now hardcoded in all the
same place (ie, the pdata path.) The port config/status code now checks
port0/port6 as appropriate to configure things.
Tested:
* Qualcomm Atheros DB120, AR8327 switch.
This is (almost!) enough to actually probe, attach, configure a default
port group and do some basic work. It's also totally hard-coded for
the Qualcomm Atheros DB120 board - it doesn't yet have any of the code
from OpenWRT which parses extra configuration data to know how to program
the switch. The LED stuff is also missing.
But, it's enough to facilitate board, PHY, switch and VLAN bringup,
so I am committing it now.

This allows the AR8327 code to override it as appropriate.
Tested:
* DB120 - AR8327 and AR9340 on-board switch; only running 'etherswitchcfg'

The registers (and perhaps the flags) are different for the AR8327, so
I'll stub those out until they're written.
Tested:

This may end up later being used as part of some logic to program

expected result.
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.

Now:
* The ar9340 switch can interconnect via MII;
* Since some slightly different phy/switch register access methods
and quirks appear for the internal versus external switch,
we will need a flag to mark it as an "internal" switch.

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.

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

Routerstation.)

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.).

than VLAN groups.
Some chips (eg this rtl8366rb) has a VLAN group per port - you first
define a set of VLANs in a vlan group, then you assign a VLAN group
to a port.
Other chips (eg the AR8xxx switch chips) have a VLAN ID array per
port - there's no group per se, just a list of vlans that can be
configured.
So for now, the switch API will use the latter and rely on drivers
doing the heavy lifting if one wishes to use the VLAN group method.
Maybe later on both can be supported.

The aim is to eventually support a full switch set and reinitialisation

Remove the port flood config from arswitch.c, it's not yet used and
it's totally incorrect.
Whilst I'm here, also add in a comment describing why the full switch
