53e58437b4 s390/qeth: Handle ambiguous OSA RCs in s390dbf
OSA Express defines a number of return codes whose meaning is determined
by the issuing command, making them ambiguous. The important ones are
reported as debug messages through the s390 debug feature.

The qeth driver currently does not take the issuing command into account
when interpreting the return code which sometimes leads to incorrect
debug messages.

Implement a mechanism to interpret and report these return codes
properly. While at it, remove extern keyword and fix indentation for
function declarations to be in line with Linux kernel coding style.

eef1f5ae73 s390/qeth: Move all OSA RCs to single enum
OSA Express defines a number of return codes whose meaning is
determined by the issuing command, making them ambiguous. Move
definitions of all return codes including the ambiguous ones to a single
enum block to aid readability and maintainability.

8e0a754b08 net: airoha: Do not loopback traffic to GDM2 if it is available on the device
Airoha_eth driver forwards offloaded uplink traffic (packets received
on GDM1 and forwarded to GDM{3,4}) to GDM2 in order to apply hw QoS.
This is correct if the device does not support a dedicated GDM2 port.
In this case, in order to enable hw offloading for uplink traffic,
the packets should be sent to GDM{3,4} directly.

28c0074fd4 r8169: bail out from probe if fiber mode is detected on RTL8127AF
It was reported that on a card with RTL8127AF (SFP + DAC) link-up isn't
detected. Realtek hides the SFP behind the internal PHY, which isn't
behaving fully compliance with clause 22 any longer in fiber mode.
Due to not having access to chip documentation there isn't much I can
do for now. Instead of silently failing to detect link-up in fiber mode,
inform the user that fiber mode isn't support and bail out.

The logic to detect fiber mode is borrowed from Realtek's r8127 driver.

24afd7827e net: phy: Add helper for fixing RGMII PHY mode based on internal mac delay
The "phy-mode" property of devicetree indicates whether the PCB has
delay now, which means the mac needs to modify the PHY mode based
on whether there is an internal delay in the mac.

This modification is similar for many ethernet drivers. To simplify
code, define the helper phy_fix_phy_mode_for_mac_delays(speed, mac_txid,
mac_rxid) to fix PHY mode based on whether mac adds internal delay.

====================
net: mana: Refactor GF stats handling and add rx_missed_errors counter

Restructure mana_query_gf_stats() to operate on the per-VF mana_context,
instead of per-port statistics. Introduce mana_ethtool_hc_stats to
isolate hardware counter statistics and update the
"ethtool -S <interface>" output to expose all relevant counters while
preserving backward compatibility.

Add support for the standard rx_missed_errors counter by mapping it
to the hardware's hc_rx_discards_no_wqe metric. Refresh statistics
every 2 seconds.

Report standard counter stats->rx_missed_errors
using hc_rx_discards_no_wqe from the hardware.

Add a global workqueue to periodically run
mana_query_gf_stats every 2 seconds to get the latest
info in eth_stats and define a driver capability flag
to notify hardware of the periodic queries.

To avoid repeated failures and log flooding, the workqueue
is not rescheduled if mana_query_gf_stats fails on HWC timeout
error and the stats are reset to 0. Other errors are transient
which will not need a VF reset for recovery.

e275d9091c net: mana: Move hardware counter stats from per-port to per-VF context
Move hardware counter (HC) statistics from mana_port_context to
mana_context to enable sharing stats across multiple network ports
on the same MANA VF. Previously, each network port queried
hardware counters independently using MANA_QUERY_GF_STAT command
(GF = Generic Function stats from GDMA hardware), resulting in
redundant queries when multiple ports existed on the same device.

Isolate hardware counter stats by introducing mana_ethtool_hc_stats
in mana_context and update the code to ensure all stats are properly
reported via ethtool -S <interface>, maintaining consistency with
previous behavior.

bed22c7b90 selftests: net: lib: Do not overwrite error messages
ret_set_ksft_status() calls ksft_status_merge() with the current return
status and the last one. It treats a non-zero return code from
ksft_status_merge() as an indication that the return status was
overwritten by the last one and therefore overwrites the return message
with the last one.

Currently, ksft_status_merge() returns a non-zero return code even if
the current return status and the last one are equal. This results in
return messages being overwritten which is counter-productive since we
are more interested in the first failure message and not the last one.

Fix by changing ksft_status_merge() to only return a non-zero return
code if the current return status was actually changed.

Add a test case which checks that the first error message is not
overwritten.

Before:

 # ./lib_sh_test.sh
 [...]
 TEST: RET tfail2 tfail -> fail                                      [FAIL]
        retmsg=tfail expected tfail2
 [...]
 # echo $?
 1

After:

 # ./lib_sh_test.sh
 [...]
 TEST: RET tfail2 tfail -> fail                                      [ OK ]

- Patch 1: move code to mptcp_lib.sh to prepare the new features.

- Patch 2: simplify mptcp_lib_pr_err_stats helper use.

- Patch 3: remove unused last column from nstat output.

- Patch 4: improve stats dump in mptcp_join.sh.

- Patch 5: get counters from nstat history and simplify mptcp_connect.sh.

- Patch 6: avoid taking the same packet trace twice.

- Patch 7: wait for an event instead of a fix time.

- Patch 8: instead of using 'timeout' and print the stats after, another
  internal timeout is used: if it fires, it will print stats, then stop
  everything. This avoids confusions around stats in case of timeout.

eea2f44870 selftests: mptcp: get stats just before timing out
Recently, some debugging happened around a test that was timing out. The
stats were showing connections being closed which was confusing because
the closing state was caused by the timeout stopping the transfer.

To avoid such confusion, the timeout is no longer done per mptcp_connect
process, but separately. In case of timeout, the stats are now printed,
then the apps are killed.

The stats will still be printed after the kill, but that's fine, and
this might even be useful, just in case. Timeout should be exceptional.

39348f5f2f selftests: mptcp: wait for port instead of sleep
After having started mptcp_connect in listening mode,
'mptcp_lib_wait_local_port_listen' can be used to wait for the listening
socket to be ready.

This is better than using the 'sleep' command, not to pause for a fixed
amount of time, but waiting for an event. This helper is used in all
other MPTCP selftests, but not in these two.

8c1fe0a500 selftests: mptcp: connect: avoid double packet traces
When the same netns is used for the listener and the connector, no need
to take exactly the same packet trace twice, one is enough.

This avoids confusions when the traces are the same, and wasting
resources which might not help reproducing an issue.

While at it, avoid long lines and double spaces now that these lines are
no longer aligned.

71388a9f33 selftests: mptcp: lib: get counters from nstat history
Before, 'nstat' was used to retrieve each individual counter: this means
querying 4 different sources from /proc/net and iterating over 100+
counters each time. Instead, the stats could be retrieved once, and the
output file could be parsed for each counter. Even better, such file is
already present: the nstat history file.

To be able to get this working, the nstat history file also needs to
contains zero counters too, so it is still possible to know if a counter
is missing or set to 0.

This also simplifies mptcp_connect.sh: instead of checking multiple
counters before and after a test to compute the difference, the stats
history files can be reset before each test, and nstat can display only
the difference.

mptcp_lib_get_counter() continues to work when no history file is
available: by fetching nstat directly, like before. This is the case in
diag.sh and userspace_pm.sh where there is no need to save the history
file. This is also the case in mptcp_join.sh, when 'run_tests' is
executed in the background: easier to continue fetching counters than
updating the history each time it is needed.

Note: 'nstat' is called with '-s' in mptcp_lib_nstat_get(), so this
helper can be called multiple times during the test if needed.

658e531417 selftests: mptcp: join: dump stats from history
In case of errors, dump the stats from history instead of using nstat.

There are multiple advantages to that:

- The same filters from pr_err_stats are used, e.g. the unused 'rate'
  column is not displayed.

- The counters are closer to the ones from when the test stopped.

- While at it, the errors can be better presented: error colours, a
  small indentation to distinguish the different parts, extra new lines.

Even if it should only happen in rare cases -- internal errors, or netns
issues -- if no history is available, 'nstat' is used like before, just
in case.

d8d8a0b360 perf tool_pmu: More accurately set the cpus for tool events
The user and system time events can record on different CPUs, but for
all other events a single CPU map of just CPU 0 makes sense. In
parse-events detect a tool PMU and then pass the perf_event_attr so
that the tool_pmu can return CPUs specific for the event. This avoids
a CPU map of all online CPUs being used for events like
duration_time. Avoiding this avoids the evlist CPUs containing CPUs
for which duration_time just gives 0. Minimizing the evlist CPUs can
remove unnecessary sched_setaffinity syscalls that delay metric
calculations.

bdf96c4ecd perf tool_pmu: Use old_count when computing count values for time events
When running in interval mode every third count of a time event isn't
showing properly:
```
$ perf stat -e duration_time -a -I 1000
     1.001082862      1,002,290,425      duration_time
     2.004264262      1,003,183,516      duration_time
     3.007381401      <not counted>      duration_time
     4.011160141      1,003,705,631      duration_time
     5.014515385      1,003,290,110      duration_time

     7.022065321      1,003,591,720      duration_time
```
The regression came in with a different fix, found through bisection,
commit 68cb156743 ("perf tool_pmu: Fix aggregation on
duration_time"). The issue is caused by the enabled and running time
of the event matching the old_count's and creating a delta of 0, which
is indicative of an error.

Fix that by jumping to err_free_rings label on error, which calls
