The purpose of commit 703eec1b2422 ("virtio_net: fixing XDP for fully
checksummed packets handling") is to record the flags in advance, as
their value may be overwritten in the XDP case. However, the flags
recorded under big mode are incorrect, because in big mode, the passed
buf does not point to the rx buffer, but rather to the page of the
submitted buffer. This commit fixes this issue.
For the small mode, the commit c11a49d58ad2 ("virtio_net: Fix mismatched
buf address when unmapping for small packets") fixed it.

====================
pull-request: can-next 2025-11-12
this is a pull request of 11 patches for net-next/main.
The first 3 patches are by Vadim Fedorenko and convert the CAN drivers
to use the ndo_hwtstamp callbacks.
Maud Spierings contributes a patch for the mcp251x driver that
converts it to use dev_err_probe().
The next 6 patches target the mcp251xfd driver and are by Gregor
Herburger and me. They add GPIO controller functionality to the
driver.
The final patch is by Chu Guangqing and fixes a typo in the bxcan
driver.

Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value, validate the result and use that to set the
control register to select the operating mode for the DWMAC core.
Note that this will allow GMII as well as MII as the phy_intf_sel
value is the same for both.

Convert dwmac-visconti to use the PHY_INTF_SEL_x definitions. The
original definitions used constant 0, BIT(0) (==1) and BIT(2) (==4)
to define these, but the values of the bits corresponds with the
PHY_INTF_SEL_x values, so it is highly likely that these are not
individual bits, but the PHY_INTF_SEL_x bitfield.
This removes this incorrect use of BIT().

Use stmmac_get_phy_intf_sel() to decode the PHY interface mode to the
phy_intf_sel value. As both configure functions would end up with the
same code, call this from stm32mp1_set_mode(), validate the result and
pass the resulting value into the stm32 configure function. Use this
value to set the operating mode for the DWMAC core.

Convert dwmac-stm32 to use the PHY_INTF_SEL_x definitions.
For stm32mp1, the original definitions used constant 0 (GMII, 0 << 21),
BIT(21) (RGMII, 1 << 21) and BIT(23) (RMII, 4 << 21) to define these,
but from the values it can be clearly seen that these are the
PHY_INTF_SEL_x inputs to the dwmac.
For stm32mp2, the original definitions cover a bitfield 6:4 in the
SYSCFG Ethernet1 control register (according to documentation) and use
the PHY_INTF_SEL_x values.
Use the common dwmac definitions for the PHY interface selection field
by adding the bitfield mask, and using FIELD_PREP() for the bitfield
values.
This removes this incorrect use of BIT().

monitor mode
To be able to capture and inject packets in monitor mode, do RF calibration
once setting certain channel. Since calibration costs time, do not change
behavior of normal usage, which do calibration only when starting as AP
or going to connect AP.
Since driver declares IEEE80211_HW_WANT_MONITOR_VIF, the pure monitor vif
must be only one when adding interface with type NL80211_IFTYPE_MONITOR.
Otherwise, monitor vif must be NULL.

The rules to diagnose MAC have a common header, and a cmd field is used
to know the exact command and its format. The rules with the same tuple of
fields {sheet, seq} can be seen as a set of compound rules, which treat
it as positive rule if just one of the rules is positive.
Take EQUALV rules as example, if value of {addr, mask} is equal to
predefined value as field val, a rule is positive. Fields addr_name_offset
and msg_offset are offsets related to textual messages for human readable.
Format of common rule header (8 bytes)
+-------+-----+--------+-----------+-----+---------+
| sheet | cmd | seq[2] | io / band | len | rsvd[2] |
+-------+-----+--------+-----------+-----+---------+
Format of rule command is EQUALV (equal value) (24 bytes):
+------+------------------+------+-----+------------+---------+
| addr | addr_name_offset | mask | val | msg_offset | rsvd[4] |
+------+------------------+------+-----+------------+---------+
Format of message:
+-----+----------+
| len | string[] |
+-----+----------+
An example of output:
Plain(Ignore)/Rules/Positive: 115(4)/86/81
Where, Plain is total rules written in firmware element.
Ignore is the ignored rules, such as USB IO, but current is PCIE.
Rules is number of set of compound rules.
Positive is number of positive Rules.

write command clears LAT0/LAT1.
Errata Fix/Work Around suggests to write registers with single byte write

causes the overwrite of LAT0/LAT1.
Never write byte 2 of IOCON register to avoid clearing of LAT0/LAT1.

Improve the readibility of the code setting ndev->max_mtu. This depends
on the hardware specific maximum defined by the MAC core, and also a
platform provided maximum.
The code was originally checking that the platform specific maximum was
between ndev->min_mtu..MAC core maximum before reducing ndev->max_mtu,
otherwise if the platform specific maximum was less than ndev->min_mtu,
issuing a warning.
Re-order the code to handle the case where the platform specific max is
below ndev->min_mtu, which then means that the subsequent test is
simply reducing ndev->max_mtu.
Update the comment, and add a few blank lines to separate the blocks of
code.

Instead of calling kernel_neon_begin/end directly, switch to the scoped
guard API which encapsulates those calls. This is needed because the
prototypes of those APIs are going to be modified and will require a
kernel mode FP/SIMD buffer to be provided, which the scoped guard API
will do transparently.

This is a preparation patch to add GPIO support.
Up to now, the Vdd regulator and the clocks have been managed by
Runtime-PM (on systems without CONFIG_PM these remain permanently
switched on).
During the mcp251xfd_open() callback the mcp251xfd is powered,
soft-reset and configured. In mcp251xfd_stop() the chip is shut down
again. To support the on-chip GPIOs, the chip must be supplied with
power while GPIOs are being requested, even if the networking
interface is down.
To support this, move the functions mcp251xfd_chip_softreset() and
mcp251xfd_chip_clock_init() from mcp251xfd_chip_start() to
mcp251xfd_runtime_resume(). Instead of setting the controller to sleep
mode in mcp251xfd_chip_stop(), bring it into configuration mode. This
way it doesn't take part in bus activity and doesn't enter sleep mode.

One of the factors of a link's grade is the channel load, which is
calculated from the AP's bss load element.
The current code takes this element from the beacon for an active link,
and from bss->ies for an inactive link.
bss->ies is set to either the beacon's ies or to the probe response
ones, with preference to the probe response (meaning that if there was
even one probe response, the ies of it will be stored in bss->ies and
won't be overiden by the beacon ies).
The probe response can be very old, i.e. from the connection time,
where a beacon is updated before each link selection (which is
triggered only after a passive scan).
In such case, the bss load element in the probe response will not
include the channel load caused by the STA, where the beacon will.
This will cause the inactive link to always have a lower channel
load, and therefore an higher grade than the active link's one.
This causes repeated link switches, causing the throughput to drop.
Fix this by always taking the ies from the beacon, as those are for
sure new.

During the development of the rate changes, I evidently made
some changes that shouldn't have been there; beacon templates
with rate_n_flags are only in old versions, so no changes to
them should have been necessary, and evidently broke on some
devices. This also would have broken fixed (injection) rates,
it would seem. Restore the old handling of this.

The list_for_each_entry() iterator must not be used outside the loop.
Even though we break and check for NULL, doing so still violates kernel
iteration rules and triggers Coccinelle's use_after_iter.cocci warning.
Cache the matched entry in aux_roc_te and use it consistently after the
loop. This follows iterator best practices, resolves the warning, and
makes the code more maintainable.
