This switch family supports four LEDs for each of its six ports. Each
LED group is composed of one of these four LEDs from all six ports. LED
groups can be configured to display hardware information, such as link
activity, or manually controlled through a bitmap in registers
RTL8366RB_LED_0_1_CTRL_REG and RTL8366RB_LED_2_3_CTRL_REG.
After a reset, the default LED group configuration for groups 0 to 3
indicates, respectively, link activity, link at 1000M, 100M, and 10M, or
RTL8366RB_LED_CTRL_REG as 0x5432. These configurations are commonly used
for LED indications. However, the driver was replacing that
configuration to use manually controlled LEDs (RTL8366RB_LED_FORCE)
without providing a way for the OS to control them. The default
configuration is deemed more useful than fixed, uncontrollable turned-on
LEDs.
The driver was enabling/disabling LEDs during port_enable/disable.
However, these events occur when the port is administratively controlled
(up or down) and are not related to link presence. Additionally, when a
port N was disabled, the driver was turning off all LEDs for group N,
not only the corresponding LED for port N in any of those 4 groups. In
such cases, if port 0 was brought down, the LEDs for all ports in LED
group 0 would be turned off. As another side effect, the driver was
wrongly warning that port 5 didn't have an LED ("no LED for port 5").
Since showing the administrative state of ports is not an orthodox way
to use LEDs, it was not worth it to fix it and all this code was
dropped.
The code to disable LEDs was simplified only changing each LED group to
the RTL8366RB_LED_OFF state. Registers RTL8366RB_LED_0_1_CTRL_REG and
RTL8366RB_LED_2_3_CTRL_REG are only used when the corresponding LED
group is configured with RTL8366RB_LED_FORCE and they don't need to be
cleaned. The code still references an LED controlled by
RTL8366RB_INTERRUPT_CONTROL_REG, but as of now, no test device has
actually used it. Also, some magic numbers were replaced by macros.

88E6250-family switches have the quirk that the EEPROM Running flag can
get stuck at 1 when no EEPROM is connected, causing
mv88e6xxx_g2_eeprom_wait() to time out. We still want to wait for the
EEPROM however, to avoid interrupting a transfer and leaving the EEPROM
in an invalid state.
The condition to wait for recommended by the hardware spec is the EEInt
flag, however this flag is cleared on read, so before the hardware reset,
is may have been cleared already even though the EEPROM has been read
successfully.
For this reason, we revive the mv88e6xxx_g1_wait_eeprom_done() function
that was removed in commit 6ccf50d4d4
("net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absent") in a
slightly refactored form, and introduce a new
mv88e6xxx_g1_wait_eeprom_done_prereset() that additionally handles this
case by triggering another EEPROM reload that can be waited on.
On other switch models without this quirk, mv88e6xxx_g2_eeprom_wait() is
kept, as it avoids the additional reload.

The MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 bits let the
PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits determine the 1G/100 EEE
abilities of the MAC. If MT7531_FORCE_EEE1G and MT7531_FORCE_EEE100 are
unset, the abilities are left to be determined by PHY auto polling.
The commit 40b5d2f15c ("net: dsa: mt7530: Add support for EEE features")
made it so that the PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 bits are set on
mt753x_phylink_mac_link_up(). But it did not set the MT7531_FORCE_EEE1G and
MT7531_FORCE_EEE100 bits. Because of this, the EEE abilities will be
determined by PHY auto polling, regardless of the result of phy_init_eee().
Define these bits and add them to the MT7531_FORCE_MODE mask which is set
in mt7531_setup_common(). With this, there won't be any EEE abilities set
when phy_init_eee() returns a negative value.
Thanks to Russell for explaining when phy_init_eee() could return a
negative value below.
Looking at phy_init_eee(), it could return a negative value when:
1. phydev->drv is NULL
2. if genphy_c45_eee_is_active() returns negative
3. if genphy_c45_eee_is_active() returns zero, it returns -EPROTONOSUPPORT
4. if phy_set_bits_mmd() fails (e.g. communication error with the PHY)
If we then look at genphy_c45_eee_is_active(), then:
genphy_c45_read_eee_adv() and genphy_c45_read_eee_lpa() propagate their
non-zero return values, otherwise this function returns zero or positive
integer.
If we then look at genphy_c45_read_eee_adv(), then a failure of
phy_read_mmd() would cause a negative value to be returned.
Looking at genphy_c45_read_eee_lpa(), the same is true.
So, it can be summarised as:
- phydev->drv is NULL
- there is a communication error accessing the PHY
- EEE is not active
otherwise, it returns zero on success.
If one wishes to determine whether an error occurred vs EEE not being
supported through negotiation for the negotiated speed, if it returns
-EPROTONOSUPPORT in the latter case. Other error codes mean either the
driver has been unloaded or communication error.
In conclusion, determining the EEE abilities by PHY auto polling shouldn't
result in having any EEE abilities enabled, when one of the last two
situations in the summary happens. And it seems that if phydev->drv is
NULL, there would be bigger problems with the device than a broken link. So
this is not a bugfix.

false, _then_ waits and end up printing the error message - that last

This driver currently doesn't support any control flags.
Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.
Only compile-tested.

The "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version)
v0.1" document shows bits 16 to 18 as the MIRROR_PORT field of the CPU
forward control register. Currently, the MT7530 DSA subdriver configures
bits 0 to 2 of the CPU forward control register which breaks the port
mirroring feature for the MT7988 SoC switch.
Fix this by using the MT7531_MIRROR_PORT_GET() and MT7531_MIRROR_PORT_SET()
macros which utilise the correct bits.

This switch intellectual property provides a bit on the ARL global control
register which controls allowing mirroring frames which are received on the
local port (monitor port). This bit is unset after reset.
This ability must be enabled to fully support the port mirroring feature on
this switch intellectual property.
Therefore, this patch fixes the traffic not being reflected on a port,
which would be configured like below:
tc qdisc add dev swp0 clsact
tc filter add dev swp0 ingress matchall skip_sw \
action mirred egress mirror dev swp0
As a side note, this configuration provides the hairpinning feature for a
single port.

Convert lantiq_gswip to provide its own phylink MAC operations, thus
avoiding the shim layer in DSA's port.c. For lantiq_gswip, it means
we end up with a common instance of phylink MAC operations that are
shared between the different variants, rather than having duplicated
initialisers in dsa_switch_ops.
