Combine all bus operations for one MMD access in one function.
Protecting all these bus operations with one lock also helps
to avoid potential issues due to bus operations intercepting
the register and data write.

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.

This add support for IGMP Snooping on atheros switches (disabled by default),
which avoids flooding the network with multicast data.
Tested on TL-WDR4300: disabling IGMP Snooping results in multicast flooding
on each specific port, enabling it back again prevents each port from
receiving all multicast packets.

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.

Adds functions for flushing ARL table entries per port.
Successfully tested on AR8327. Implementation for AR8216/AR8236/AR8316
is based on the AR8236 datasheet and assumes that the three chips
share a common ATU register layout.
Compile-tested only for AR8216/AR8236/AR8316.

AR8337 supports a configuration bit to swap MAC0 and MAC6.
Currently this is set in general if an AR8337 is detected and causes
issues with devices using an AR8334 (internally an AR8337, just
less chip pins).
And it might even cause issues with AR8337-based devices with
different board designs.
Swapping the MAC's however isn't needed for AR8337 in general.
It's just needed in case of certain board designs (affected devices
seem to be based on Atheros reference board AP135/136-010).
Therefore this configuration bit should be moved to platform data.
The patch includes the needed changes to the device initialization
code of affected devices. Hopefully I didn't miss any ..

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)
and TL-WDR4900 (AR8327rev4).

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.
Successfully tested on TL-WDR4900 (AR8327 rev.4) and

If EEE is autonegotiated between the link partners, display
this as part of the swconfig 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.
