Before layer 2 forwarding, the device classifies an incoming packet to a
FID. After classification, the FID is known, but also all the attributes of
the FID, such as the router interface (RIF) via which a packet that needs
to be routed will ingress the router block.
For VLAN-unaware bridges (802.1D), the FID classification is done according
to {Port, VID}. When a RIF is added on top of a FID, all the existing
{Port, VID}->FID mappings should be updated by the software with the new
RIF. In addition, when a new mapping is added for FID which already has a
RIF, the correct RIF should be used for it.
Add a test to verify that packets can be routed after {Port, VID}->FID
classification, regardless of the order of the configuration.
# ./ingress_rif_conf_1d.sh
TEST: Add RIF for existing {port, VID}->FID mapping [ OK ]
TEST: Add {port, VID}->FID mapping for FID with a RIF [ OK ]

Add DT property to disable hibernation mode
The patches add the ability to disable the hibernation mode of AR803x
PHYs. Hibernation mode defaults to enabled after hardware reset on
these PHYs. If the AR803x PHYs enter hibernation mode, they will not
provide any clock. For some MACs, they might need the clocks which
provided by the PHYs to support their own hardware logic.
So, the patches add the support to disable hibernation mode by adding
a boolean:
qca,disable-hibernation-mode
If one wished to disable hibernation mode to better match with the
specifical MAC, just add this property in the phy node of DT.

When the cable is unplugged, the Atheros AR803x PHYs will enter
hibernation mode after about 10 seconds if the hibernation mode
is enabled and will not provide any clock to the MAC. But for
some MACs, this feature might cause unexpected issues due to the
logic of MACs.
Taking SYNP MAC (stmmac) as an example, if the cable is unplugged
and the "eth0" interface is down, the AR803x PHY will enter
hibernation mode. Then perform the "ifconfig eth0 up" operation,
the stmmac can't be able to complete the software reset operation
and fail to init it's own DMA. Therefore, the "eth0" interface is
failed to ifconfig up. Why does it cause this issue? The truth is
that the software reset operation of the stmmac is designed to
depend on the RX_CLK of PHY.
So, this patch offers an option for the user to determine whether
to disable the hibernation mode of AR803x PHYs.

The hibernation mode of Atheros AR803x PHYs defaults to be
enabled after hardware reset. When the cable is unplugged,
the PHY will enter hibernation mode after about 10 seconds
and the PHY clocks will be stopped to save power.
However, some MACs need the phy output clock for proper
functioning of their logic. For instance, stmmac needs the
RX_CLK of PHY for software reset to complete.
Therefore, add a DT property to configure the PHY to disable
this hardware hibernation mode.

Make sure that entire libbpf code base is initializing bpf_attr and
perf_event_attr with memset(0). Also for bpf_attr make sure we
clear and pass to kernel only relevant parts of bpf_attr. bpf_attr is
a huge union of independent sub-command attributes, so there is no need
to clear and pass entire union bpf_attr, which over time grows quite
a lot and for most commands this growth is completely irrelevant.
Few cases where we were relying on compiler initialization of BPF UAPI
structs (like bpf_prog_info, bpf_map_info, etc) with `= {};` were
switched to memset(0) pattern for future-proofing.

This patch brings-in support for t7xx wwan device firmware flashing &
coredump collection using devlink.
Driver Registers with Devlink framework.
Implements devlink ops flash_update callback that programs modem firmware.
Creates region & snapshot required for device coredump log collection.
On early detection of wwan device in fastboot mode driver sets up CLDMA0 HW
tx/rx queues for raw data transfer then registers with devlink framework.
Upon receiving firmware image & partition details driver sends fastboot
commands for flashing the firmware.
In this flow the fastboot command & response gets exchanged between driver
and device. Once firmware flashing is success completion status is reported
to user space application.
Below is the devlink command usage for firmware flashing
$devlink dev flash pci/$BDF file ABC.img component ABC
Note: ABC.img is the firmware to be programmed to "ABC" partition.
In case of coredump collection when wwan device encounters an exception
it reboots & stays in fastboot mode for coredump collection by host driver.
On detecting exception state driver collects the core dump, creates the
devlink region & reports an event to user space application for dump
collection. The user space application invokes devlink region read command
for dump collection.
Below are the devlink commands used for coredump collection.
devlink region new pci/$BDF/mr_dump
devlink region read pci/$BDF/mr_dump snapshot $ID address $ADD length $LEN
devlink region del pci/$BDF/mr_dump snapshot $ID

This introduces a few statistics similar to the ones already available in

If the PTP hardware clock is adjusted, the ice driver must update the
cached PHC timestamp. This is required in order to perform timestamp
extension on the shorter timestamps captured by the PHY.
Currently, we simply call ice_ptp_update_cached_phctime in the settime and
adjtime callbacks. This has a few issues:
1) if ICE_CFG_BUSY is set because another thread is updating the Rx rings,
we will exit with an error. This is not checked, and the functions do
not re-schedule the update. This could leave the cached timestamp
incorrect until the next scheduled work item execution.
2) even if we did handle an update, any currently outstanding Tx timestamp
would be extended using the wrong cached PHC time. This would produce
incorrect results.
To fix these issues, introduce a new ice_ptp_reset_cached_phctime function.
This function calls the ice_ptp_update_cached_phctime, and discards
outstanding Tx timestamps.
If the ice_ptp_update_cached_phctime function fails because ICE_CFG_BUSY is
set, we log a warning and schedule the thread to execute soon. The update
function is modified so that it always updates the cached copy in the PF
regardless. This ensures we have the most up to date values possible and
minimizes the risk of a packet timestamp being extended with the wrong
value.
It would be nice if we could skip reporting Rx timestamps until the cached
values are up to date. However, we can't access the Rx rings while
ICE_CFG_BUSY is set because they are actively being updated by another
thread.

The ice driver requires a cached copy of the PHC time in order to perform
timestamp extension on Tx and Rx hardware timestamp values. This cached PHC
time must always be updated at least once every 2 seconds. Otherwise, the
math used to perform the extension would produce invalid results.
The updates are supposed to occur periodically in the PTP kthread work
item, which is scheduled to run every half second. Thus, we do not expect
an update to be delayed for so long. However, there are error conditions
which can cause the update to be delayed.
Track this situation by using jiffies to determine approximately how long
ago the last update occurred. Add a new statistic and a dev_warn when we
have failed to update the cached PHC time. This makes the error case more
obvious.

The bpftool self-created maps can appear in final map show output due to
deferred removal in kernel. These maps don't have a name, which would make
users confused about where it comes from.
With a libbpf_ prefix name, users could know who created these maps.
It also could make some tests (like test_offload.py, which skip base maps
without names as a workaround) filter them out.
Kernel adds bpf prog/map name support in the same merge
commit fadad670a8 ("Merge branch 'bpf-extend-info'"). So we can also use
kernel_supports(NULL, FEAT_PROG_NAME) to check if kernel supports map name.
As discussed [1], Let's make bpf_map_create accept non-null
name string, and silently ignore the name if kernel doesn't support.

Pull more ACPI updates from Rafael Wysocki:
"These fix up direct references to the fwnode field in struct device
and extend ACPI device properties support.
Specifics:
- Replace direct references to the fwnode field in struct device with
dev_fwnode() and device_match_fwnode() (Andy Shevchenko)
- Make the ACPI code handling device properties support properties
with buffer values (Sakari Ailus)"

Pull more iomap updates from Darrick Wong:
"In the past 10 days or so I've not heard any ZOMG STOP style
complaints about removing ->writepage support from gfs2 or zonefs, so
here's the pull request removing them (and the underlying fs iomap
support) from the kernel:
- Remove iomap_writepage and all callers, since the mm apparently
never called the zonefs or gfs2 writepage functions"
* tag 'iomap-6.0-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
iomap: remove iomap_writepage
