The cpumask should not be a local variable, since its pointer is saved
to irq_desc and may be accessed from procfs.
To fix it, use the persistent mask cpumask_of(cpu#).

Realtek RTL8211F has a "PHY-mode" EEE support which interferes with an
IEEE 802.3 compliant implementation. This mode defaults to enabled, and
results in the MAC receive path not seeing the link transition to LPI
state.

Commit 809265fe96fe ("net: phy: c45: remove local advertisement
parameter from genphy_c45_eee_is_active") stopped reading the local
advertisement from the PHY earlier in this development cycle, which
broke "ethtool --set-eee ethX eee off".
When ethtool is used to set EEE off, genphy_c45_eee_is_active()
indicates that EEE was active if the link partner reported an
advertisement, which causes phylib to set phydev->enable_tx_lpi on
link up, despite our local advertisement in hardware being empty.
However, phydev->advertising_eee is preserved while EEE is turned off,
which leads to genphy_c45_eee_is_active() incorrectly reporting that
EEE is active.
Fix it by checking phydev->eee_cfg.eee_enabled, and if clear,
immediately indicate that EEE is not active.

The code was incorrectly relying on PCAM bit of ppcnt_statistical_group
for accessing per_lane_error_counters.
If ppcnt_statistical_group PCAM bit was not set, we would not read
per_lane_error_counters, even when its PCAM bit is set.
Given the existing device capabilities, it seems to cause no harm, so

The ravb_ptp_extts() function checks the flags coming from the
PTP_EXTTS_REQUEST ioctl, to ensure that future flags are not accepted on
accident.
This was updated to 'honor' the PTP_STRICT_FLAGS in commit 6138e687c7b6
("ptp: Introduce strict checking of external time stamp options.").
However, the driver does not *actually* validate the flags.
I originally fixed this driver to reject future flags in commit
592025a03b34 ("renesas: reject unsupported external timestamp flags"). It
is still unclear whether this hardware timestamps the rising, falling, or
both edges of the input signal.
Accepting requests with PTP_STRICT_FLAGS is a bug, as this could lead to
users mistakenly assuming a request with PTP_RISING_EDGE actually
timestamps the rising edge only.
Reject requests with PTP_STRICT_FLAGS (and hence all PTP_EXTTS_REQUEST2
requests) until someone with access to the datasheet or hardware knowledge
can confirm the timestamping behavior and update this driver.

The igb_ptp_feature_enable_82580 function correctly checks that unknown
flags are not passed to the function. However, it does not actually check
PTP_RISING_EDGE or PTP_FALLING_EDGE when configuring the external timestamp
function.
The data sheet for the 82580 product says:
Upon a change in the input level of one of the SDP pins that was
configured to detect Time stamp events using the TSSDP register, a time
stamp of the system time is captured into one of the two auxiliary time
stamp registers (AUXSTMPL/H0 or AUXSTMPL/H1).
For example to define timestamping of events in the AUXSTMPL0 and
AUXSTMPH0 registers, Software should:
1. Set the TSSDP.AUX0_SDP_SEL field to select the SDP pin that detects
the level change and set the TSSDP.AUX0_TS_SDP_EN bit to 1.
2. Set the TSAUXC.EN_TS0 bit to 1 to enable timestamping
The same paragraph is in the i350 and i354 data sheets.
The wording implies that the time stamps are captured at any level change.
There does not appear to be any way to only timestamp one edge of the
signal.
Reject requests which do not set both PTP_RISING_EDGE and PTP_FALLING_EDGE
when operating under PTP_STRICT_FLAGS mode via PTP_EXTTS_REQUEST2.

phy_loopback() leaves it to the PHY driver to select the speed of the
loopback mode. Thus, the speed of the loopback mode depends on the PHY
driver in use.
Add support for speed selection to phy_loopback() to enable loopback
with defined speeds. Ensure that link up is signaled if speed changes
as speed is not allowed to change during link up. Link down and up is
necessary for a new speed.

PHY drivers support loopback mode, but it is not possible to select the
speed of the loopback mode. The speed is chosen by the set_loopback()
operation of the PHY driver. Same is valid for genphy_loopback().
There are PHYs that support loopback with different speeds. Extend
set_loopback() to make loopback speed selection possible.

When a character array without a terminating NUL character has a static
initializer, GCC 15's -Wunterminated-string-initialization will only
warn if the array lacks the "nonstring" attribute[1]. Mark the arrays
with __nonstring to correctly identify the char array as "not a C string"
and thereby eliminate the warning:

Everywhere else in the driver uses devm_kzalloc() when allocating the
AXI data, so there is no kfree() of this structure. However,
dwc-qos-eth uses kzalloc(), which leads to this memory being leaked.
Switch to use devm_kzalloc().

The DWMAC 1000 DMA capabilities register does not provide actual
FIFO sizes, nor does the driver really care. If they are not
provided via some other means, the driver will work fine, only
disallowing changing the MTU setting.
Provide the FIFO sizes through the driver's platform data to enable
MTU changes. The FIFO sizes are confirmed to be the same across RK3288,
RK3328, RK3399 and PX30, based on their respective manuals. It is
likely that Rockchip synthesized their DWMAC 1000 with the same
parameters on all their chips that have it.

Whether the MII transmit clock can be stopped is primarily a property
of the PHY (there is a capability bit that should be checked first.)
Whether the MAC is capable of stopping the transmit clock is a separate
issue, but this is already handled by the core DesignWare MAC code.
Therefore, snps,en-tx-lpi-clockgating is technically incorrect, and
this commit adds a warning should a DT be encountered with the property
present.
However, we keep backwards compatibility.
