Currently, mlo_capable_flags is set to zero if dualmac device is
detected based on One Time Programmable (OTP) register value.
This is not generic and in future dualmac devices may support
Single Link Operation (SLO) and Multi Link Operation (MLO).
Thus, set mlo_capable_flags based on 'single_chip_mlo_support'
parameter from QMI PHY capability response message from the firmware.
Also, add check on mlo_capable_flags to disable MLO parameter in the
host capability QMI request message.
If the firmware does not respond with this optional parameter
'single_chip_mlo_support' in QMI PHY capability response, default
ab->mlo_capable_flags is used.

New parameter 'single_chip_mlo_support' was added in QMI PHY
capability response message. This is an optional parameter added
in QCN9274 firmware. This parameter states if the firmware
supports Single-Link Operation (SLO) and Multi-Link Operation (MLO)
within the same device.
If single_chip_mlo_support = 1, then intra device SLO/MLO is supported
in the firmware.
If single_chip_mlo_support = 0, then intra device SLO/MLO is not
supported in the firmware.
Hence, add support to read 'single_chip_mlo_support' parameter from
the QMI PHY capability response message.

When AP goes down or too far away without indication to STA, beacon miss
will be detected. Then for WCN7850's firmware, it will use roam event
to send beacon miss to host.
If STA doesn't handle the beacon miss, will keep the fake connection
and unable to roam.
So add support for WCN7850 to trigger disconnection from AP when
receiving this event from firmware.
It has to be noted that beacon miss event notification for QCN9274
to be handled in a separate patch as it uses STA kickout WMI event
to notify beacon miss and the current STA kickout event is processed
as low_ack.

The TDX guest platform takes one bit from the physical address to
indicate if the page is shared (accessible by VMM). This bit is not part
of the physical_mask and is not preserved during mprotect(). As a
result, the 'shared' bit is lost during mprotect() on shared mappings.
_COMMON_PAGE_CHG_MASK specifies which PTE bits need to be preserved
during modification. AMD includes 'sme_me_mask' in the define to
preserve the 'encrypt' bit.
To cover both Intel and AMD cases, include 'cc_mask' in
_COMMON_PAGE_CHG_MASK instead of 'sme_me_mask'.

The controller has several register bits describing access control
information for a given GPIO pin. When SCR_SEC_[R|W]EN is unset, it
means we have full read/write access to all the registers for given GPIO
pin. When SCR_SEC[R|W]EN is set, it means we need to further check the
accompanying SCR_SEC_G1[R|W] bit to determine read/write access to all
the registers for given GPIO pin.
This check was previously declaring that a GPIO pin was accessible
only if either of the following conditions were met:
- SCR_SEC_REN + SCR_SEC_WEN both set
or
- SCR_SEC_REN + SCR_SEC_WEN both set and
SCR_SEC_G1R + SCR_SEC_G1W both set
Update the check to properly handle cases where only one of
SCR_SEC_REN or SCR_SEC_WEN is set.

With deferred IO enabled, a page fault happens when data is written to the
framebuffer device. Then driver determines which page is being updated by
calculating the offset of the written virtual address within the virtual
memory area, and uses this offset to get the updated page within the
internal buffer. This page is later copied to hardware (thus the name
"deferred IO").
This offset calculation is only correct if the virtual memory area is
mapped to the beginning of the internal buffer. Otherwise this is wrong.
For example, if users do:
mmap(ptr, 4096, PROT_WRITE, MAP_FIXED | MAP_SHARED, fd, 0xff000);
Then the virtual memory area will mapped at offset 0xff000 within the
internal buffer. This offset 0xff000 is not accounted for, and wrong page
is updated.
Correct the calculation by using vmf->pgoff instead. With this change, the
variable "offset" will no longer hold the exact offset value, but it is
rounded down to multiples of PAGE_SIZE. But this is still correct, because
this variable is only used to calculate the page offset.

cpu_feature_enabled(X86_FEATURE_OSPKE) does not necessarily reflect
whether CR4.PKE is set on the CPU. In particular, they may differ on
non-BSP CPUs before setup_pku() is executed. In this scenario, RDPKRU
will #UD causing the system to hang.
Fix by checking CR4 for PKE enablement which is always correct for the
current CPU.
The scenario happens by inserting a WARN* before setup_pku() in
identiy_cpu() or some other diagnostic which would lead to calling
__show_regs().

net: sparx5: add support for port mirroring
This series adds support for port mirroring, and port mirroring stats,
through tc matchall action FLOW_ACTION_MIRRED.
The hardware has three independent mirroring probes. Each probe can be
configured with a separate set of filtering conditions that must be
fulfilled before traffic is mirrored.
A mirror probe can have up to 64 source ports and a single monitor port.
The direction of a mirror probe determines if rx or tx traffic is
mirrored from the source port to the monitor port.

The hardware supports three independent mirroring probes. Each probe can
be configured to mirror rx or tx traffic (direction).
Using tc matchall, it is now possible to add a source port and a monitor
port to a mirror probe. Depending on the mirror direction, rx or tx
traffic from a source port will be mirrored to the monitor port.
A single source port can be a member of multiple mirror probes.

allocate dummy device dynamically
struct net_device shouldn't be embedded into any structure, instead,
the owner should use the private space to embed their state into
net_device.
But, in some cases the net_device is embedded inside the private
structure, which blocks the usage of zero-length arrays inside
net_device.
Create a helper to allocate a dummy device at dynamically runtime, and
move the Ethernet devices to use it, instead of embedding the dummy
device inside the private structure.
This fixes all the network cases plus some wireless drivers.
PS: Due to lack of hardware, unfortunately most these patches are
compiled tested only, except ath11k that was kindly tested by Kalle Valo.

It is impossible to use init_dummy_netdev together with alloc_netdev()
as the 'setup' argument.
This is because alloc_netdev() initializes some fields in the net_device
structure, and later init_dummy_netdev() memzero them all. This causes
some problems as reported here:
https://lore.kernel.org/all/20240322082336.49f110cc@kernel.org/
Split the init_dummy_netdev() function in two. Create a new function called
init_dummy_netdev_core() that does not memzero the net_device structure.
Then have init_dummy_netdev() memzero-ing and calling
init_dummy_netdev_core(), keeping the old behaviour.
init_dummy_netdev_core() is the new function that could be called as an
argument for alloc_netdev().
Also, create a helper to allocate and initialize dummy net devices,
leveraging init_dummy_netdev_core() as the setup argument. This function
basically simplify the allocation of dummy devices, by allocating and
initializing it. Freeing the device continue to be done through
free_netdev()

For dummy devices, exit earlier at free_netdev() instead of executing
the whole function. This is necessary, because dummy devices are
special, and shouldn't have the second part of the function executed.
Otherwise reg_state, which is NETREG_DUMMY, will be overwritten and
there will be no way to identify that this is a dummy device. Also, this
device do not need the final put_device(), since dummy devices are not
registered (through register_netdevice()), where the device reference is
increased (at netdev_register_kobject()/device_add()).

Unlike MT7531BE, the GPIO 6-12 pins are not used for RGMII on MT7531AE.
Therefore, the GPIO 11-12 pins are set to function as MDC and MDIO to
expose the MDIO bus of the switch. Replace the comment with a better
explanation.

With the support of the MT7988 SoC switch, the MAC speed capabilities
defined on mt753x_phylink_get_caps() won't apply to all switch models
anymore. Move them to more appropriate locations instead of overwriting
config->mac_capabilities.
Remove the comment on mt753x_phylink_get_caps() as it's become invalid with
the support of MT7531 and MT7988 SoC switch.

On MT7530, the media-independent interfaces of port 5 and 6 are controlled
by the MT7530_P5_DIS and MT7530_P6_DIS bits of the hardware trap. Deal with
these bits only when the relevant port is being enabled or disabled. This
ensures that these ports will be disabled when they are not in use.
Do not set MT7530_CHG_TRAP on mt7530_setup_port5() as that's already being
done on mt7530_setup().
Instead of globally setting MT7530_P5_MAC_SEL, clear it, then set it only
on the appropriate case.
If PHY muxing is detected, clear MT7530_P5_DIS before calling
mt7530_setup_port5().

The MT7530_HWTRAP and MT7530_MHWTRAP registers are on MT7530 and MT7531.
It's called hardware trap on MT7530, software trap on MT7531. That's
because some bits of the trap on MT7530 cannot be modified by software
whilst all bits of the trap on MT7531 can. Rename the definitions for them
to MT753X_TRAP and MT753X_MTRAP. Add MT7530 and MT7531 prefixes to the
definitions specific to the switch model.
Remove the extra parentheses from MT7530_XTAL_40MHZ and MT7530_XTAL_20MHZ.
Rename MHWTRAP_PHY0_SEL, MHWTRAP_MANUAL, and MHWTRAP_PHY_ACCESS to be on
par with the "MT7621 Giga Switch Programming Guide v0.3" document.

The p5_intf_sel pointer is used to store the information of whether PHY
muxing is used or not. PHY muxing is a feature specific to port 5 of the
MT7530 switch. Do not use it for other switch models.
Rename the pointer to p5_mode to store the mode the port is being used in.
Rename the p5_interface_select enum to mt7530_p5_mode, the string
representation to mt7530_p5_mode_str, and the enum elements.

The MT7530_PMCR_P() registers are on MT7530, MT7531, and the switch on the

for MT7530 only. Add MT7530 prefix to the definition for bit 15.
Use GENMASK and FIELD_PREP for PMCR_IFG_XMIT().
Rename PMCR_TX_EN and PMCR_RX_EN to PMCR_MAC_TX_EN and PMCR_MAC_TX_EN to

"MT7531 Reference Manual for Development Board v1.0", and "MT7988A Wi-Fi 7
Generation Router Platform: Datasheet (Open Version) v0.1" documents.
These documents show that PMCR_RX_FC_EN is at bit 5. Correct this along
with renaming it to PMCR_FORCE_RX_FC_EN, and the same for PMCR_TX_FC_EN.
Remove PMCR_SPEED_MASK which doesn't have a use.

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 40b5d2f15c09 ("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.

Only blink if the link is up on a LED which is programmed to also
indicate link-status.
Otherwise, if both LEDs are in use to indicate different speeds, the
resulting blinking being inverted on LEDs which aren't switched on at
a specific speed is quite counter-intuitive.
Also make sure that state left behind by reset or the bootloader is
recognized correctly including the half-duplex and full-duplex bits as
well as the (unsupported by Linux netdev trigger semantics) link-down
bit.

Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal
of gtp_dellink, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and
the key will be free.
To prevent this, it should be changed to hlist_for_each_entry_safe.
