There are too many MIB counters that almost nobody needs since commit
d6366ce366 ("generic: ar8216: mib_work_func: read all port mibs
everytime").
In the worker function to poll MIB data, it deals with all ports instead
of only one port every time, which introduces too many mdio operations
that it becomes a heavy CPU load even on not-emulated MDIO bus.
This commit groups MIB counters and enable only TxBytes and RxGoodBytes
by default (both of which are necessary to get swconfig led working.)
and adds an swconfig attribute to allow enabling all counters if users
need them.

This allows specifying interval of polling MIB counters from userspace
and allow completely turning off MIB counter support by setting
mib_poll_interval to 0.
Since MIB counter polling is a heavy CPU load for GPIO emulated MDIO
bus, disable this behavior by default. Those who wants to use swconfig
LEDs can enable them with qca,mib-poll-interval dts property or with
swconfig command.

This allows users to specify a shorter mib poll interval so that the

Partially reverts commit eff3549c58.
AR7240 and AR9341 have buggy hardware switch LED trigger. The AR7240
one doesn't blink and the blinking of port0/port5 is reversed on
AR9341 if we swap PHY0 and PHY4. (Only blinking is reversed, which
means LED for PHY0 will lit when PHY0 is link up and will blink when
PHY4 has active link and vice versa.) On these two chips a software
swconfig LED trigger is required.
This commit adds swconfig port stats back but:
1. move checking of mib_t/rxb_id into ar8xxx_chip since we can't
distinguish ar7240sw and ar8216 using only chip id.
2. don't update mib counter in get_port_stat. This function is called
every 0.01s and this capturing procedure will take up a lot of CPU.
We already have a mib_work_func updating mib counters every 2s so
return the saved counter instead of fetching new data. The blinking
rate will be weird but it should solve the previously mentioned CPU
time problem.

This builtin switch is a bugless ar8216 with different mib counters
and gigabit cpu port.
Atheros uses the same device ID and it's impossible to distinguish
the standalone one and the builtin one. So we add support to mdio
device probe only.
This switch doesn't have buggy vlan tag so it's not needed to enable
atheros header. This commit changed ar8216_setup_port so that it can
be reused for this switch.

Atheros FE switches have a builtin mdio master available for PHY
accessing and on ar724x/ar933x builtin switches this mdio master
is the only way of accessing PHYs.
After this patch if there is phy_read/phy_write method available
in ar8xxx_chip we register a separated mdio bus for accessing PHYs.
Still adds support for mdio device probing only since this isn't
needed for those switches registered using PHY probing.

ar8229 is the builtin switch in ar934x and later chips. There is
also a standalone version available and their registers/functions
are the same.
This commit added support for the builtin ar8229. The only thing
missing for standalone ar8229 should be phy modes. Since I don't
have a router using that, this commit doesn't add support for
other phy modes.
Only add its support for mdio-device probing method because the
current PHY probing can't return 1G speed when it's a FE switch.

The existing ar8327 driver does not have support for

for the same. This has been verified on AP148 and AP161

The implementation is not efficient on ar8xxx switches. It triggers high
CPU load and degrades device performance.
The high CPU load has been traced down to the ar8xxx_reg_wait() call in
ar8xxx_mib_op(), which has to usleep_range() till the MIB busy flag set
by the request to update the MIB counter is cleared.
This commit removes the get_port_stats() code introduced in 4d8a66d and
leaves a note for future hacker's beware.

This patch provides a generic switch_dev_ops 'get_port_stats()' callback by
taping into the relevant port MIB counters.
The implementation uses a generic callback that select the correct MIB counter
index based on chip version.
This callback is used by swconfig_leds led trigger to blink LEDs with port

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.

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.

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.

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.
