Commit ad72c4a06acc introduced optimization to return from function
quickly if the MAC address is not changing at all. It was reported
that such change causes dev->addr_assign_type to not change
to NET_ADDR_SET from _PERM or _RANDOM.
Restore the old behavior and skip only call to ndo_set_mac_address.
Fixes: ad72c4a06acc ("net: add check for current MAC address in dev_set_mac_address")

In a setup where a Thunderbolt hub connects to Ethernet and a display
through USB Type-C, users may experience a hung task timeout when they
remove the cable between the PC and the Thunderbolt hub.
This is because the igb_down function is called multiple times when
the Thunderbolt hub is unplugged. For example, the igb_io_error_detected
triggers the first call, and the igb_remove triggers the second call.
The second call to igb_down will block at napi_synchronize.
Here's the call trace:

In this case, igb_io_error_detected detaches the network interface
and requests a PCIE slot reset, however, the PCIE reset callback is
not being invoked and thus the Ethernet connection breaks down.
As the PCIE error in this case is a non-fatal one, requesting a
slot reset can be avoided.
This patch fixes the task hung issue and preserves Ethernet
connection by ignoring non-fatal PCIE errors.

====================
net: dsa: microchip: fix writes to phy registers >= 0x10
Patch 1 is just a simplification, technically unrelated to the other
two patches. But it would be a bit inconsistent to have the new
ksz_prmw32() introduced in patch 2 use ksz_rmw32() while leaving
ksz_prmw8() as-is.
The actual fix is of course patch 3. I can definitely see some weird
behaviour on our ksz9567 when writing to phy registers 0x1e and 0x1f
(with phytool from userspace), though it does not seem that the effect
is always to write zeroes to the buddy register as the errata sheet
says would be the case. In our case, the switch is connected via i2c;
I hope somebody with other switches and/or the SPI variants can test
this.

According to the errata sheets for ksz9477 and ksz9567, writes to the
PHY registers 0x10-0x1f (i.e. those located at addresses 0xN120 to
0xN13f) must be done as a 32 bit write to the 4-byte aligned address
containing the register, hence requires a RMW in order not to change
the adjacent PHY register.

Przemek suggests that I shouldn't accuse GCC of witchcraft,
there is a simpler explanation for why we need manual define.
scripts/headers_install.sh modifies the guard, removing _UAPI.
That's why including a kernel header from the tree and from
/usr leads to duplicate definitions.
This also solves the mystery of why I needed to include
the header conditionally. I had the wrong guards for most
cases but ethtool.

Fix an issue where the kernel would stall during netboot, showing the
"sched: RT throttling activated" message. This stall was triggered by
the behavior of the mii_interrupt bit (Bit 7 - DP83TD510E_STS_MII_INT)
in the DP83TD510E's PHY_STS Register (Address = 0x10). The DP83TD510E
datasheet (2020) states that the bit clears on write, however, in
practice, the bit clears on read.
This discrepancy had significant implications on the driver's interrupt
handling. The PHY_STS Register was used by handle_interrupt() to check
for pending interrupts and by read_status() to get the current link
status. The call to read_status() was unintentionally clearing the
mii_interrupt status bit without deasserting the IRQ pin, causing
handle_interrupt() to miss other pending interrupts. This issue was most
apparent during netboot.
The fix refrains from using the PHY_STS Register for interrupt handling.
Instead, we now solely rely on the INTERRUPT_REG_1 Register (Address =
0x12) and INTERRUPT_REG_2 Register (Address = 0x13) for this purpose.
These registers directly influence the IRQ pin state and are latched
high until read.
Note: The INTERRUPT_REG_2 Register (Address = 0x13) exists and can also
be used for interrupt handling, specifically for "Aneg page received
interrupt" and "Polarity change interrupt". However, these features are
currently not supported by this driver.

Russell King says:
====================
Add and use helper for PCS negotiation modes
Earlier this month, I proposed a helper for deciding whether a PCS
should use inband negotiation modes or not. There was some discussion
around this topic, and I believe there was no disagreement about
providing the helper.
The initial discussion can be found at:
https://lore.kernel.org/r/ZGIkGmyL8yL1q1zp@shell.armlinux.org.uk
Subsequently, I posted a RFC series back in May:
https://lore.kernel.org/r/ZGzhvePzPjJ0v2En@shell.armlinux.org.uk
that added a helper, phylink_pcs_neg_mode() which PCS drivers could use
to parse the state, and updated a bunch of drivers to use it. I got
a couple of bits of feedback to it, including some ACKs.
However, I've decided to take this slightly further and change the
"mode" parameter to both the pcs_config() and pcs_link_up() methods
when a PCS driver opts in to this (by setting "neg_mode" in the
phylink_pcs structure.) If this is not set, we default to the old
behaviour. That said, this series converts all the PCS implementations
I can find currently in net-next.
Doing this has the added benefit that the negotiation mode parameter
is also available to the pcs_link_up() function, which can now know
whether inband negotiation was in fact enabled or not at pcs_config()
time.
It has been posted as RFC at:
https://lore.kernel.org/r/ZIh/CLQ3z89g0Ua0@shell.armlinux.org.uk
and received one reply, thanks Elad, which is a similar amount of
interest to previous postings. Let's post it as non-RFC and see
whether we get more reaction.

PCS have to work out whether they should enable PCS negotiation by
looking at the "mode" and "interface" arguments, and the Autoneg bit
in the advertising mask.
This leads to some complex logic, so lets pull that out into phylink
and instead pass a "neg_mode" argument to the PCS configuration and
link up methods, instead of the "mode" argument.
In order to transition drivers, add a "neg_mode" flag to the phylink
PCS structure to PCS can indicate whether they want to be passed the
neg_mode or the old mode argument.

syzbot reported a possible deadlock in netlink_set_err() [1]
A similar issue was fixed in commit 1d482e666b8e ("netlink: disable IRQs
for netlink_lock_table()") in netlink_lock_table()
This patch adds IRQ safety to netlink_set_err() and __netlink_diag_dump()
which were not covered by cited commit.
[1]
WARNING: possible irq lock inversion dependency detected
6.4.0-rc6-syzkaller-00240-g4e9f0ec38852 #0 Not tainted
syz-executor.2/23011 just changed the state of lock:
ffffffff8e1a7a58 (nl_table_lock){.+.?}-{2:2}, at: netlink_set_err+0x2e/0x3a0 net/netlink/af_netlink.c:1612
but this lock was taken by another, SOFTIRQ-safe lock in the past:
(&local->queue_stop_reason_lock){..-.}-{2:2}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:
CPU0 CPU1
---- ----
lock(nl_table_lock);
local_irq_disable();
lock(&local->queue_stop_reason_lock);
lock(nl_table_lock);

Commit 49725ffc15fc ("net: stmmac: power up/down serdes in
stmmac_open/release") correctly added a call to the serdes_powerdown()
callback to stmmac_release() but did not remove the one from
stmmac_remove() which leads to a doubled call to serdes_powerdown().
This can lead to all kinds of problems: in the case of the qcom ethqos
driver, it caused an unbalanced regulator disable splat.
