Add global read-only swconfig attribute "arl_table" to display the
address resolution table.
So far the chip-specific part is implemented for AR8327/AR8337 only
as I don't have the datasheets for the other AR8XXX chips.
Successfully tested on TL-WDR4300 (AR8327rev2)

Until a few years ago the page switch wait time was set to msleep(1)
what was changed to usleep_range(1000, 2000) later.
I can not imagine that a low-level operation like switching page
on register level takes so much time.
Most likely the value of 1ms was initially set to check whether
it fixes an issue and then remained w/o further checking whether
also a smaller value would be sufficient.
Now the wait time is set to 5us and I successfully tested this on
AR8327. IMHO 5us should be plenty of time for all supported chips.
However I couldn't test this due to missing hardware.
If other chips should need a longer wait time we can add the
wait time as a parameter to the ar8xxx_chip struct.

Check for switch port link changes and
- flush ATU in case of a change
- report link change via syslog
Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com>
SVN-Revision: 44102
The functionality to flush the address translation table contains two bugs
which luckily compensate each other.
1. Just setting the operation is not sufficient to perform the flushing.
The "active" bit needs to be set to actually trigger an action.
For the vtu operations this is implemented correctly.
2. ar8xxx_phy_read_status is called every 2s by the phy state machine
to check for link changes. This would have caused an ATU flush
every 2s.
Fix the chip-specific ATU flush functions and remove the ATU flush call
from ar8xxx_phy_read_status.

The swconfig get_link attribute (at least) on AR8327/AR8337 doesn't
consider the autonegotiated flow control.
AR8327/AR8337 provide the info about autonegotiated rx/tx flow control
in bits 10 and 11 of the port status register.
Use these values to display info about autonegotiated rx/tx flow
control as part of the get_link attribute.

Users reported network issues with AR8327 which turned out to be caused
by EEE not working correctly with certain link partners (ticket 14597).
The workaround was to disable EEE on all ports (changeset 41577).
The issue was with certain link partners only, therefore this patch
allows to control usage of EEE per port via swconfig.
Still the default is to initially disable EEE on all ports.

Remove read/write/rmw member functions from ar8xxx_priv
There seems to be no real benefit of the ar8xxx_priv member functions
read/write/rmw as one implementation exists for each of them only.
Especially ar8xxx_mii_rmw is assigned to priv->rmw first and then
mapped to ar8xxx_rmw.
Rename the ar8xxx_mii_.. functions to ar8xxx_.. and use them directly.

Kernel 3.14 introduced a switch reset in phy_init_hw in drivers/net/phy
causing BMCR_ANENABLE to get cleared.
Due to the fact that ar8xxx_phy_config_aneg does nothing for
PHY 0 autonegatiation support remains disabled.
This can cause ports to operate at 10MBit/half-duplex only.
Fix this by calling genphy_config_aneg for PHY 0 too as
genphy_config_aneg sets BMCR_ANENABLE if it's not yet set.

This allows tagged and untagged traffic together on the same port on ar8327
switch devices.
I looked at the first attempt to do this in r40777 (ar71xx: Fix tagged+untagged
operation on AR8327N (#12181)). I also set the vlan and port egress policies
like that change. But I change vlan_tagged in an less intrusive way. The
tagged/untagged decision is now based on the following rules:
- if vid != pvid then traffic is always tagged
- if vid == pvid then vlan_tagged stores if the traffic should be tagged
