Make the architecture-optimized CRC code do its CPU feature checks in
subsys_initcalls instead of arch_initcalls. This makes it consistent
with arch/*/lib/crypto/ and ensures that it runs after initcalls that
possibly could be a prerequisite for kernel-mode FPU, such as x86's
xfd_update_static_branch() and loongarch's init_euen_mask().
Note: as far as I can tell, x86's xfd_update_static_branch() isn't
*actually* needed for kernel-mode FPU. loongarch's init_euen_mask() is
needed to enable save/restore of the vector registers, but loongarch
doesn't yet have any CRC or crypto code that uses vector registers
anyway. Regardless, let's be consistent with arch/*/lib/crypto/ and
robust against any potential future dependency on an arch_initcall.

each with a length of 'send', and every time we send this part of the data
using tcp_bpf_sendmsg_redir(), we use sk_msg_return_zero() to uncharge the

However, if the first segment of data fails to send, for example, the

So, during setting channel, also re-calculate the MLO DBCC mode flag.
Then, leaf chip functions of setting channel can configure with HWs

Besides, tweak the initial and idle MLO DBCC mode of Wi-Fi 7 chips to
MLO_1_PLUS_1_1RF to work with dual HW bands. And, after disconnecting,

Some users have RTL8723DS chips with nearly blank efuse. Currently these
chips cannot connect when using rtw88, but they do work using the old
out-of-tree driver.
Use reasonable default values for TX power, antenna configuration, and
crystal cap if the chip's efuse is missing these things.
RTL8723D can use the same default values as RTL8703B, so simply move
the code from rtl8703b_read_efuse() to the shared function
__rtl8723x_read_efuse().

====================
Refactoring designware VLAN code.
Refactoring designware VLAN code and introducing support for
hardware-accelerated VLAN stripping for dwxgmac2 IP,
the current patch set consists of two key changes:
1) Refactoring VLAN Functions:
The first change involves moving common VLAN-related functions
of the DesignWare Ethernet MAC into a dedicated file, stmmac_vlan.c.
This refactoring aims to improve code organization and maintainability
by centralizing VLAN handling logic.
2) Renaming all the functions, symbols and macro into more
generic name and consolidate the same function pointer into one.
3) Enabling VLAN for 10G Ethernet MAC IP:
The second change enables VLAN support specifically
for the 10G Ethernet MAC IP. This enhancement leverages
the hardware capabilities of the to perform VLAN stripping,
Changes from previous submmited patches.
v5:
a) Divided the refactor patch in to two patches,
first patch is to move the code into the separate file
and second patch to update the symbol name
b) get the dwmac4 vlan function up to date and port to
stmmac_vlan.c
c) remove the inline function in function pointer and
use only static function defeination.
d) Remove the outer parenthese that is not needed
on the 1 line return statement.
v4:
a) Updated the commit message to explain the descriptors
behaviour on different hardware.
b) Updated the perfect_match variable with the correct
byte order.

This patch adds support for MAC level VLAN tag stripping for the
dwxgmac2 IP. This feature can be configured through ethtool.
If the rx-vlan-offload is off, then the VLAN tag will be stripped
by the driver. If the rx-vlan-offload is on then the VLAN tag
will be stripped by the MAC.

With the VLAN handling code decoupled from dwmac4 and dwxgmac2 and
consolidated in stmmac_vlan.c, functions and symbols are renamed to
use a generic prefix. This change improves code clarity and
maintainability by reflecting the shared nature of the VLAN logic,
facilitating future enhancements or reuse without being tied to
specific MAC implementations.
No functional changes are introduced in this patch.
Note: The dwxgmac2_update_vlan_hash function is not combined due
to minor differences in setting the VTFE bit. A separate fix patch
will be submitted to align its behavior with the dwmac4 driver.

Refactor VLAN implementation by moving common code for DWMAC4 and
DWXGMAC IPs into a separate VLAN module. VLAN implementation for
DWMAC4 and DWXGMAC differs only for CSR base address, the descriptor
for the VLAN ID and VLAN VALID bit field.
The descriptor format for VLAN is not moved to the common code due
to hardware-specific differences between DWMAC4 and DWXGMAC.
For the DWMAC4 IP, the Receive Normal Descriptor 0 (RDES0) is
formatted as follows:
31 0
------------------------ -----------------------
RDES0| Inner VLAN TAG [31:16] | Outer VLAN TAG [15:0] |
------------------------ -----------------------
For the DWXGMAC IP, the RDES0 format varies based on the
Tunneled Frame bit (TNP):
a) For Non-Tunneled Frame (TNP=0)
31 0
------------------------ -----------------------
RDES0| Inner VLAN TAG [31:16] | Outer VLAN TAG [15:0] |
------------------------ -----------------------
b) For Tunneled Frame (TNP=1)
31 8 7 3 2 0
--------------------- ------------------ -------
RDES0| VNID/VSID | Reserved | OL2L3 |
--------------------- ------------------ ------
The logic for handling tunneled frames is not yet implemented
in the dwxgmac2_wrback_get_rx_vlan_tci() function. Therefore,
it is prudent to maintain separate functions within their
respective descriptor driver files
(dwxgmac2_descs.c and dwmac4_descs.c).

New timestamping API was introduced in commit 66f7223039 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6. It is
time to convert the mvpp2 driver to the new API, so that the
ndo_eth_ioctl() path can be removed completely.
Note that on the !port->hwtstamp condition, the old code used to fall
through in mvpp2_ioctl(), and return either -ENOTSUPP if !port->phylink,
or -EOPNOTSUPP, in phylink_mii_ioctl(). Keep the test for port->hwtstamp
in the newly introduced net_device_ops, but consolidate the error code
to just -EOPNOTSUPP. The other one is documented as NFS-specific, it's
best to avoid it anyway.

Don't propagate the unnecessary "config.flags = 0;" assignment to
gfar_hwtstamp_get(), because dev_get_hwtstamp() provides a zero
initialized struct kernel_hwtstamp_config.
After removing timestamping logic from gfar_ioctl(), the rest is
equivalent to phy_do_ioctl_running(), so provide that directly as our
ndo_eth_ioctl() implementation.

Vladimir Oltean says:
====================
dpaa_eth conversion to ndo_hwtstamp_get() and ndo_hwtstamp_set()
This is part of the effort to finalize the conversion of drivers to the
dedicated hardware timestamping API.
In the case of the DPAA1 Ethernet driver, a bit more care is needed,
because dpaa_ioctl() looks a bit strange. It handles the "set" IOCTL but
not the "get", and even the phylink_mii_ioctl() portion could do with
some cleanup.

phylink_mii_ioctl() handles multiple ioctls in addition to just
SIOCGMIIREG: SIOCGMIIPHY, SIOCSMIIREG. Don't filter these out.
Also, phylink can handle the case where net_dev->phydev is NULL (like
optical SFP module, fixed-link). Be like other drivers and let phylink
do so without any driver-side call filtering.

New timestamping API was introduced in commit 66f7223039 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6. It is
time to convert DSA to the new API, so that the ndo_eth_ioctl() path can
be removed completely.
Move the ds->ops->port_hwtstamp_get() and ds->ops->port_hwtstamp_set()
calls from dsa_user_ioctl() to dsa_user_hwtstamp_get() and
dsa_user_hwtstamp_set().
Due to the fact that the underlying ifreq type changes to
kernel_hwtstamp_config, the drivers and the Ocelot switchdev front-end,
all hooked up directly or indirectly, must also be converted all at once.
The conversion also updates the comment from dsa_port_supports_hwtstamp(),
which is no longer true because kernel_hwtstamp_config is kernel memory
and does not need copy_to_user(). I've deliberated whether it is
necessary to also update "err != -EOPNOTSUPP" to a more general "!err",
but all drivers now either return 0 or -EOPNOTSUPP.
The existing logic from the ocelot_ioctl() function, to avoid
configuring timestamping if the PHY supports the operation, is obsoleted
by more advanced core logic in dev_set_hwtstamp_phylib().
This is only a partial preparation for proper PHY timestamping support.
None of these switch driver currently sets up PTP traps for PHY
timestamping, so setting dev->see_all_hwtstamp_requests is not yet
necessary and the conversion is relatively trivial.

When CONFIG_PROVE_RCU_LIST is enabled, fprobe triggers the following
warning:
WARNING: suspicious RCU usage
kernel/trace/fprobe.c:457 RCU-list traversed in non-reader section!!
other info that might help us debug this:
#1: ffffffff863c4e08 (fprobe_mutex){+.+.}-{4:4}, at: fprobe_module_callback+0x7b/0x8c0
Call Trace:
fprobe_module_callback
notifier_call_chain
blocking_notifier_call_chain
This warning occurs because fprobe_remove_node_in_module() traverses an
RCU list using RCU primitives without holding an RCU read lock. However,
the function is only called from fprobe_module_callback(), which holds
the fprobe_mutex lock that provides sufficient protection for safely
traversing the list.
Fix the warning by specifying the locking design to the
CONFIG_PROVE_RCU_LIST mechanism. Add the lockdep_is_held() argument to
hlist_for_each_entry_rcu() to inform the RCU checker that fprobe_mutex
provides the required protection.

Symmetric RSS hash requires that:
* No other fields besides IP src/dst and/or L4 src/dst are set
* If src is set, dst must also be set
This restriction was only enforced when RXNFC was configured after
symmetric hash was enabled. In the opposite order of operations (RXNFC
then symmetric enablement) the check was not performed.
Perform the sanity check on set_rxfh as well, by iterating over all flow
types hash fields and making sure they are all symmetric.
Introduce a function that returns whether a flow type is hashable (not
spec only) and needs to be iterated over. To make sure that no one
forgets to update the list of hashable flow types when adding new flow
types, a static assert is added to draw the developer's attention.
The conversion of uapi #defines to enum is not ideal, but as Jakub
mentioned [1], we have precedent for that.

mctp_flow_prepare_output() is called in mctp_route_output(), which
places outbound packets onto a given interface. The packet may represent
a message fragment, in which case we provoke an unbalanced reference
count to the underlying device. This causes trouble if we ever attempt
to remove the interface:
[ 48.702195] usb 1-1: USB disconnect, device number 2
[ 58.883056] unregister_netdevice: waiting for mctpusb0 to become free. Usage count = 2
[ 69.022548] unregister_netdevice: waiting for mctpusb0 to become free. Usage count = 2
[ 79.172568] unregister_netdevice: waiting for mctpusb0 to become free. Usage count = 2
...
Predicate the invocation of mctp_dev_set_key() in
mctp_flow_prepare_output() on not already having associated the device
with the key. It's not yet realistic to uphold the property that the key
maintains only one device reference earlier in the transmission sequence
as the route (and therefore the device) may not be known at the time the
key is associated with the socket.

skb_tx_timestamp() is used for tx software timestamp enabled by
SOF_TIMESTAMPING_TX_SOFTWARE while SKBTX_HW_TSTAMP is used for
SOF_TIMESTAMPING_TX_HARDWARE. As it clearly shows they are different
timestamps in two dimensions, it's not appropriate to group these two
together in the if-statement.
This patch completes three things:
1. make the software one standalone. Users are able to set both
timestamps together with SOF_TIMESTAMPING_OPT_TX_SWHW flag.
2. make the software one generated after the hardware timestamp logic to
avoid generating sw and hw timestamps at one time without
SOF_TIMESTAMPING_OPT_TX_SWHW being set.
3. move the software timestamp call as close to the door bell.

The PMIC GLINK driver is currently generating DisplayPort hotplug
notifications whenever something is connected to (or disconnected from)
a port regardless of the type of notification sent by the firmware.
These notifications are forwarded to user space by the DRM subsystem as
connector "change" uevents:
KERNEL[1556.223776] change /devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0 (drm)
ACTION=change
DEVPATH=/devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0
SUBSYSTEM=drm
HOTPLUG=1
CONNECTOR=36
DEVNAME=/dev/dri/card0
DEVTYPE=drm_minor
SEQNUM=4176
MAJOR=226
MINOR=0
On the Lenovo ThinkPad X13s and T14s, the PMIC GLINK firmware sends two
identical notifications with orientation information when connecting a
charger, each generating a bogus DRM hotplug event. On the X13s, two
such notification are also sent every 90 seconds while a charger remains
connected, which again are forwarded to user space:
port = 1, svid = ff00, mode = 255, hpd_state = 0
payload = 01 00 00 00 00 00 00 ff 00 00 00 00 00 00 00 00
Note that the firmware only sends on of these when connecting an
ethernet adapter.
Fix the spurious hotplug events by only forwarding hotplug notifications
for the Type-C DisplayPort service id. This also reduces the number of
uevents from four to two when an actual DisplayPort altmode device is
connected:
port = 0, svid = ff01, mode = 2, hpd_state = 0
payload = 00 01 02 00 f2 0c 01 ff 03 00 00 00 00 00 00 00
