1263d07b89 kernel: ar83xx: add support to configure per port VLAN priority
Add support to allow for per switch port VLAN priority (PCP) bits
for the ar8327/8337 chip using the swconfig utility.

Tested on Netgear R7800

967b6be118 ar8327: Add workarounds for AR8337 switch.
RGMII RX delay setting needs to be always specified for AR8337 to
avoid port 5 RX hang on high traffic / flood conditions.

Also, the HOL registers that set per-port and per-packet-priority
buffer sizes are updated with the reduced values suggested by the
QCA switch team.

Finally, AR8327 reserved register fixups are disabled for the AR8337.

This patch is adapted from the Code Aurora QSDK, but with magic
values mapped to proper defines.

d3776bdfc9 AR8216: make ARL age time configurable
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.

f8d2ec6e9d ar8327: add IGMP Snooping support
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.

00e599b0b7 ar8216: add ARL table flushing per port
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.

3a313a3e11 ar8216: add swconfig attribute to display ARL table on AR8327/AR8337
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).

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).

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)
