The priv->vlan_id member is of size AR8X16_MAX_VLANS, not AR8X16_MAX_PORTS,
so check for the proper maximum value in order to avoid capping valid VLAN IDs
to 7 (AR8X16_MAX_PORTS - 1).

Enable flow control of LAN and WAN ports to
get better performance.
Setup pvid as 0 for all ports during initialisation
to avoid confusion during system or switch INIT.
Disable PORT MAC before config MAC to avoid it work abnormal.
This change is for IR-054144, IR-057315.

CHROMIUM: drivers: ar8216: prevent device duplication in ar8xxx_dev_list
If probe is called twice, once for PHY0 and a second time for PHY4,
the same switch device will be added twice to ar8xxx_dev_list, while
supposedly this list should have one element per hardware switch present
in the system.
While no negative impact have been observed, it does happen if a
platform instanciates these two PHYs from device-tree, as an example.

CHROMIUM: drivers: ar8216: hold ar8xxx_dev_list_lock during use_count--
It is possible for the remove() callback to run twice in parallel, which
could result into --use_count returning only 1 in both cases and the
rest of the unregistration path to never be reached.
This case has never been observed in practice, but we will fix
preventively to make the code more robust.

The commit "generic: ar8216: add sanity check to ar8216_probe"
(774da6c7a40320a320b28d71291c0e61fcf7bc8a) stated that PHY IDs
should be checked at address 0-4. However, the PHY 4 was
never check by the loop. This patch extends the check to be
similar to the Atheors SDK. It tries all 4 ports and skips
unconnected PHYs if necessary. If it cannot find any familiar
PHYs, it will prevent the phy driver from initializing.
This patch is necessary for the C-60. It doesn't have a
PHY at port 3, so this caused the check in ar8xxx_is_possible
to fail. As a result, the ethernet ports on the C-60 didn't
work.

Some devices (e.g. Tenda AC9 based on BCM47189B0) have BCM53125 with
port 5 connected to the second Ethernet interface on the SoC. In such
case there is no PHY and we need to force link manually.
This assumes port 5 can be marked as enabled for such devices. It's not
implemented yet unfortunately.

Our code was assuming CPU port uses the highest number. My BCM53573
device has eth0 connected to port 8 and eth1 connected to port 5. While
working on support for it I tried to:
1) Enable all ports (including port 8)
2) Set CPU port to 5
I noticed port 8 is not accessible anymore. It was just a development
process but it seems like something worth fixing anyway.

The swconfig kernel infrastructure fails to do any permissions checks when
changing settings. As such an ordinary user account on a device with a
switch can change switch settings without any special permissions.
Routers generally have few non-admin users so this isn't a big hole, but it
is a security hole. Likely the greatest danger is for multifunction devices
which have a lot of extra daemons, compromising a low-security daemon would
allow one to modify switch settings and cause the router/switch to appear to
lock-up (or cause other sorts of troublesome nyetwork behavior).
Implement a check for CAP_NET_ADMIN in swconfig_set_attr() and deny any
requests originating from user contexts lacking this capability.

The default TTL for address resolution table entries is 5 minutes
for all members of the AR8216 family. This can cause issues if
e.g. Wifi clients roam to another AP and their MAC appears on
another switch port suddenly. Then the client may not be reachable
until the old ARL entry expires.
I would have expected the switch to invalidate old entries if it
detects the same MAC on another port. But that's not the case.
Therefore make the TTL for ARL entries configurable.
The effective TTL will always be a multiple of 7 seconds.

For unused switch ports all MIB values are zero. Displaying ~40 empty

This patch adds speed_mask special file to LEDs connected to switch ports
via 'switch' trigger. It allows to choose which speeds to signal when link
is up. If router has more than one LED per port, they may light up
differently depending on how fast connection is. Default setting is 'all
speeds' so backward compatibility with system scripts (for example uci) is
maintained.

So far we were sending link data as a string. It got some drawbacks:
1) Didn't allow writing clean user space apps reading link state. It was
needed to do some screen scraping.
2) Forced whole PORT_LINK communication to be string based. Adding
support for *setting* port link required passing string and parting
it in the kernel space.

In r45970 the MAC swap handling was made opt-in, however some boards
have been forgotten during the conversion. Since the reference design
uses this MAC swapping, and pretty much all known boards using this chip
seem to do so too, enabling the swapping is a more reasonable default
than leaving it disabled.
Change the code to still allow boards to opt-out of this.

This also clears any bootloader-set FDB defaults. This had
caused issues creating port-based VLANs when mappings
overlapped previous VLANs. Packets destined to a port
not in the default port group flooded all ports.

Adds the chip-specific part of reading ARL table for AR8216/AR8236/AR8316.
It's based on the AR8236 datasheet and compile-tested only as I couldn't
find datasheets for AR8216/AR8316 and don't own devices with these chips.
The existing ar8216_atu_flush implementation was used for all three
chip types, therefore I guess they share a common ATU register layout.
More testing would be appreciated.
