74146c62c0 ar8216: fix ATU flushing
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.

6dfea16ab9 ar8216: display flow control info in swconfig get_link in case of autonegatiation too
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
TL-WDR4300 (AR8327 rev.2).

53c0c6054f ar8216: add 802.3az EEE info to swconfig get_link attribute
AR8327/AR8337 allow to read the result of EEE autonegotiation.
If EEE is autonegotiated between the link partners, display
this as part of the swconfig get_link attribute.

eee100:  100MBit EEE supported by both link partners
eee1000: 1GBit EEE supported by both link partners

bdc0750191 ar8216: introduce enable_eee swconfig attribute to control 802.3az EEE per port
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.

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

1cbf0fbcb4 ar8216: factor out AR8327/AR8337-specific driver code into ar8327.c
Move all AR8327/AR8337-specific driver code into a separate source file
ar8327.c and adjust patches so that ar8327.c is compiled if
CONFIG_AR8216_PHY is set.
