After removal of the invalid command counter only a relevant debug
message is left, which can be cumbersome. So add a new flag to debugfs,
which indicates whether the driver has ever received a valid CMD.
This helps to differentiate between general and temporary receive
issues.

There are several reasons for an invalid command response
by the MSE102x:
* SPI line interferences
* MSE102x is in reset or has no firmware
* MSE102x is busy
* no packet in MSE102x receive buffer
So the counter for invalid command isn't very helpful without
further context. So drop the confusing statistics counter,
but keep the debug messages about "unexpected response" in order
to debug possible hardware issues.

It has been reported that when under a bridge with stp_state=1, the logs
get spammed with this message:
[ 251.734607] fsl_dpaa2_eth dpni.5 eth0: Couldn't decode source port
Further debugging shows the following info associated with packets:
source_port=-1, switch_id=-1, vid=-1, vbid=1
In other words, they are data plane packets which are supposed to be
decoded by dsa_tag_8021q_find_port_by_vbid(), but the latter (correctly)
refuses to do so, because no switch port is currently in
BR_STATE_LEARNING or BR_STATE_FORWARDING - so the packet is effectively
unexpected.
The error goes away after the port progresses to BR_STATE_LEARNING in 15
seconds (the default forward_time of the bridge), because then,
dsa_tag_8021q_find_port_by_vbid() can correctly associate the data plane
packets with a plausible bridge port in a plausible STP state.
Re-reading IEEE 802.1D-1990, I see the following:
"4.4.2 Learning: (...) The Forwarding Process shall discard received
frames."
IEEE 802.1D-2004 further clarifies:
"DISABLED, BLOCKING, LISTENING, and BROKEN all correspond to the
DISCARDING port state. While those dot1dStpPortStates serve to
distinguish reasons for discarding frames, the operation of the
Forwarding and Learning processes is the same for all of them. (...)
LISTENING represents a port that the spanning tree algorithm has
selected to be part of the active topology (computing a Root Port or
Designated Port role) but is temporarily discarding frames to guard
against loops or incorrect learning."
Well, this is not what the driver does - instead it sets
mac[port].ingress = true.
To get rid of the log spam, prevent unexpected data plane packets to
be received by software by discarding them on ingress in the LISTENING
state.
In terms of blame attribution: the prints only date back to commit
d7f9787a763f ("net: dsa: tag_8021q: add support for imprecise RX based
on the VBID"). However, the settings would permit a LISTENING port to
forward to a FORWARDING port, and the standard suggests that's not OK.

__netdev_update_features() expects the netdevice to be ops-locked, but
it gets called recursively on the lower level netdevices to sync their
features, and nothing locks those.
This commit fixes that, with the assumption that it shouldn't be possible
for both higher-level and lover-level netdevices to require the instance
lock, because that would lead to lock dependency warnings.
Without this, playing with higher level (e.g. vxlan) netdevices on top
of netdevices with instance locking enabled can run into issues:

Most PHY drivers default to a 2ns delay if internal delay is requested
and no value is specified. Having a default value makes sense, as it
allows a Device Tree to only care about board design (whether there are
delays on the PCB or not), and not whether the delay is added on the MAC
or the PHY side when needed.
Whether the delays are actually applied is controlled by the
DP83867_RGMII_*_CLK_DELAY_EN flags, so the behavior is only changed in
configurations that would previously be rejected with -EINVAL.

The check that intended to handle "rgmii" PHY mode differently to the
RGMII modes with internal delay never worked as intended:
- added in commit 2a10154abcb7 ("net: phy: dp83867: Add TI dp83867 phy"):
logic error caused the condition to always evaluate to true
- changed in commit a46fa260f6f5 ("net: phy: dp83867: Fix warning check
for setting the internal delay"): now the condition incorrectly
evaluates to false for rgmii-txid
- removed in commit 2b892649254f ("net: phy: dp83867: Set up RGMII TX
delay")
Around the time of the removal, commit c11669a2757e ("net: phy: dp83867:
Rework delay rgmii delay handling") started clearing the delay enable
flags in RGMIICTL. The change attempted to preserve the historical
behavior of not disabling internal delays with "rgmii" PHY mode and also
documented this in a comment, but due to a conflict between "Set up
RGMII TX delay" and "Rework delay rgmii delay handling", the behavior
dp83867_verify_rgmii_cfg() warned about (and that was also described in
a comment in dp83867_config_init()) disappeared in the following merge
of net into net-next in commit b4b12b0d2f02
("Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net").
While is doesn't appear that this breaking change was intentional, it
has been like this since 2019, and the new behavior to disable the delays
with "rgmii" PHY mode is generally desirable - in particular with MAC
drivers that have to fix up the delay mode, resulting in the PHY driver
not even seeing the same mode that was specified in the Device Tree.
Remove the obsolete check and comment.

There is a situation where after THALT is set high, TGO stays high as
well. Because jiffies are never updated, as we are in a context with
interrupts disabled, we never exit that loop and have a deadlock.
That deadlock was noticed on a sama5d4 device that stayed locked for days.
Use retries instead of jiffies so that the timeout really works and we do
not have a deadlock anymore.

selftests: net: configure rp_filter in setup_ns
Some distributions enable rp_filter globally by default, which can interfere
with various test cases. To address this, many tests explicitly disable
rp_filter within their scripts.
To avoid duplication and ensure consistent behavior across tests, this patch
moves the rp_filter configuration into setup_ns, applied immediately after a
new namespace is created. This change ensures that all namespace-based tests
inherit the appropriate rp_filter settings, simplifying individual test
scripts and improving maintainability.

Switch bareudp testing to use setup_ns, which sets up rp_filter by default.
This allows us to remove the manual rp_filter configuration from the script.
Additionally, since setup_ns handles namespace naming and cleanup, we no
longer need a separate cleanup function. We also move the trap setup earlier
in the script, before the test setup begins.

Some distributions enable rp_filter globally by default. To ensure consistent
behavior across environments, we explicitly disable it in several test cases.
This patch moves the rp_filter disabling logic to immediately after the
network namespace is initialized. With this change, individual test cases
with creating namespace via setup_ns no longer need to disable rp_filter
again.
This helps avoid redundancy and ensures test consistency.

New timestamping API was introduced in commit 66f7223039c0 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6. It is
time to convert the intel ixp4xx ethernet driver to the new API, so that
the ndo_eth_ioctl() path can be removed completely.
hwtstamp_get() and hwtstamp_set() are only called if netif_running()
when the code path is engaged through the legacy ioctl. As I don't
want to make an unnecessary functional change which I can't test,
preserve that restriction when going through the new operations.
When cpu_is_ixp46x() is false, the execution of SIOCGHWTSTAMP and
SIOCSHWTSTAMP falls through to phy_mii_ioctl(), which may process it in
case of a timestamping PHY, or may return -EOPNOTSUPP. In the new API,
the core handles timestamping PHYs directly and does not call the netdev
driver, so just return -EOPNOTSUPP directly for equivalent logic.
A gratuitous change I chose to do anyway is prefixing hwtstamp_get() and
hwtstamp_set() with the driver name, ipx4xx. This reflects modern coding
sensibilities, and we are touching the involved lines anyway.
The remainder of eth_ioctl() is exactly equivalent to
phy_do_ioctl_running(), so use that.

If btrfs_reserve_extent() fails while submitting an async_extent for a
compressed write, then we fail to call free_async_extent_pages() on the
async_extent and leak its folios. A likely cause for such a failure
would be btrfs_reserve_extent() failing to find a large enough
contiguous free extent for the compressed extent.
I was able to reproduce this by:
1. mount with compress-force=zstd:3
2. fallocating most of a filesystem to a big file
3. fragmenting the remaining free space
4. trying to copy in a file which zstd would generate large compressed
extents for (vmlinux worked well for this)
Step 4. hits the memory leak and can be repeated ad nauseam to
eventually exhaust the system memory.
Fix this by detecting the case where we fallback to uncompressed
submission for a compressed async_extent and ensuring that we call
free_async_extent_pages().

If the discard worker is running and there's currently only one block
group, that block group is a data block group, it's in the unused block
groups discard list and is being used (it got an extent allocated from it
after becoming unused), the worker can end up in an infinite loop if a
transaction abort happens or the async discard is disabled (during remount
or unmount for example).
This happens like this:
1) Task A, the discard worker, is at peek_discard_list() and
find_next_block_group() returns block group X;
2) Block group X is in the unused block groups discard list (its discard
index is BTRFS_DISCARD_INDEX_UNUSED) since at some point in the past
it become an unused block group and was added to that list, but then
later it got an extent allocated from it, so its ->used counter is not
zero anymore;
3) The current transaction is aborted by task B and we end up at
__btrfs_handle_fs_error() in the transaction abort path, where we call
btrfs_discard_stop(), which clears BTRFS_FS_DISCARD_RUNNING from
fs_info, and then at __btrfs_handle_fs_error() we set the fs to RO mode
(setting SB_RDONLY in the super block's s_flags field);
4) Task A calls __add_to_discard_list() with the goal of moving the block
group from the unused block groups discard list into another discard
list, but at __add_to_discard_list() we end up doing nothing because
btrfs_run_discard_work() returns false, since the super block has
SB_RDONLY set in its flags and BTRFS_FS_DISCARD_RUNNING is not set
anymore in fs_info->flags. So block group X remains in the unused block
groups discard list;
5) Task A then does a goto into the 'again' label, calls
find_next_block_group() again we gets block group X again. Then it
repeats the previous steps over and over since there are not other
block groups in the discard lists and block group X is never moved
out of the unused block groups discard list since
btrfs_run_discard_work() keeps returning false and therefore
__add_to_discard_list() doesn't move block group X out of that discard
list.
When this happens we can get a soft lockup report like this:

When using trace_array_printk() on a created instance, the correct
function to use to initialize it is:
trace_array_init_printk()
Not
trace_printk_init_buffer()
The former is a proper function to use, the latter is for initializing
trace_printk() and causes the NOTICE banner to be displayed.

For older/32-bit systems with highmem, don't assume that the pages in
a mapped region are always going to be mapped. If io_region_init_ptr()
finds that the pages are coalescable, also check if the first page is
a HighMem page or not. If it is, fall through to the usual vmap()
mapping rather than attempt to get the unmapped page address.

We don't need the configs that won't end up being used, such as
the "br" config for discrete devices, remove them. Also remove
the module firmware for test chips, that's never needed.
For now keep the iwl_dr_mac_cfg even if it's unused, we'll add
platforms with it once we have their PCI IDs.

Now that it's all split into MAC and RF configs, remove
the matching on MAC type and step. If we ever need to do
something based on the MAC step, we'll have to find some
new mechanism (since the MAC type is known already from
the PCI IDs table, but not the step), or just handle the
(likely small) differences in code.
