By overlaying the struct gve_xdp_buff on top of the struct xdp_buff_xsk
that AF_XDP utilizes, the driver records the 32 bit timestamp via the
completion descriptor and the cached 64 bit NIC timestamp via gve_priv.
The driver's implementation of xmo_rx_timestamp extends the timestamp to
the full and up to date 64 bit timestamp and returns it to the user.
gve_rx_xsk_dqo is modified to accept a pointer to the completion
descriptor and no longer takes a buf_len explicitly as it can be pulled
out of the descriptor.
With this patch gve now supports bpf_xdp_metadata_rx_timestamp.

Support populating XDP RX metadata with hardware RX timestamps. This
patch utilizes the same underlying logic to calculate hardware
timestamps as the regular RX path.
xdp_metadata_ops is registered with the net_device in a future patch.
gve_rx_calculate_hwtstamp was pulled out so as to not duplicate logic
between gve_xdp_rx_timestamp and gve_rx_hwtstamp.

RX timestamping will need to keep track of extra temporary information
per-packet. In preparation for this, introduce gve_xdp_buff to wrap the
xdp_buff. This is similar in function to stmmac_xdp_buff and
ice_xdp_buff.

Previously, gve had been only initializing ptp aux work when
hardware timestamping was initialized through ndo_hwtsatmp_set. As this
patch series introduces XDP hardware timestamp metadata which will
require the ptp aux work, the work can't be gated on the
kernel_hwtstamp_config being set and must be initialized elsewhere.
For simplicity, ptp_schedule_worker is invoked right after the ptp_clock
is registered with the kernel (which happens during gve_probe or
following reset). The worker is scheduled in GVE_NIC_TS_SYNC_INTERVAL_MS
as the synchronous call to gve_clock_nic_ts_read makes the worker
redundant if scheduled immediately.
If gve cannot read the device clock immediately, it errors out of
gve_init_clock.

The lan8814 supports two interfaces towards the host (QSGMII and QUSGMII).
Currently the lan8814 disables the auto-negotiation towards the host
side. So, extend this to allow to configure to use in-band
auto-negotiation.
I have tested this only with the QSGMII interface.

Add selftests to verify and document Linux’s intended behaviour for
UNIX domain sockets (SOCK_STREAM and SOCK_DGRAM) when a peer closes.
The tests verify that:
1. SOCK_STREAM returns EOF when the peer closes normally.
2. SOCK_STREAM returns ECONNRESET if the peer closes with unread data.
3. SOCK_SEQPACKET returns EOF when the peer closes normally.
4. SOCK_SEQPACKET returns ECONNRESET if the peer closes with unread data.
5. SOCK_DGRAM does not return ECONNRESET when the peer closes.
This follows up on review feedback suggesting a selftest to clarify
Linux’s semantics.

On the Renesas RZ/V2H EVK platform, where the stmmac MAC is connected to a
Microchip KSZ9131RNXI PHY, creating or deleting VLAN interfaces may fail
with timeouts:
# ip link add link end1 name end1.5 type vlan id 5
15c40000.ethernet end1: Timeout accessing MAC_VLAN_Tag_Filter
RTNETLINK answers: Device or resource busy
Disabling EEE at runtime avoids the problem:
# ethtool --set-eee end1 eee off
# ip link add link end1 name end1.5 type vlan id 5
# ip link del end1.5
The stmmac hardware requires the receive clock to be running when writing
certain registers, such as those used for MAC address configuration or
VLAN filtering. However, by default the driver enables Energy Efficient
Ethernet (EEE) and allows the PHY to stop the receive clock when the link
is idle. As a result, the RX clock might be stopped when attempting to
access these registers, leading to timeouts and other issues.
Commit dd557266cf5fb ("net: stmmac: block PHY RXC clock-stop")
addressed this issue for most register accesses by wrapping them in
phylink_rx_clk_stop_block()/phylink_rx_clk_stop_unblock() calls.
However, VLAN add/delete operations may be invoked with bottom halves
disabled, where sleeping is not allowed, so using these helpers is not
possible.
Therefore, to fix this, disable the RX clock stop feature in the phylink
configuration if VLAN features are set. This ensures the RX clock remains
active and register accesses succeed during VLAN operations.

When the "rx-vlan-filter" feature is enabled on a network device, the 8021q
module automatically adds a VLAN 0 hardware filter when the device is
brought administratively up.
For stmmac, this causes vlan_add_hw_rx_fltr() to create a new entry for
VID 0 in the mac_device_info->vlan_filter array, in the following format:
VLAN_TAG_DATA_ETV | VLAN_TAG_DATA_VEN | vid
Here, VLAN_TAG_DATA_VEN indicates that the hardware filter is enabled for
that VID.
However, on the delete path, vlan_del_hw_rx_fltr() searches the vlan_filter
array by VID only, without verifying whether a VLAN entry is enabled. As a
result, when the 8021q module attempts to remove VLAN 0, the function may
mistakenly match a zero-initialized slot rather than the actual VLAN 0
entry, causing incorrect deletions and leaving stale entries in the
hardware table.
Fix this by verifying that the VLAN entry's enable bit (VLAN_TAG_DATA_VEN)
is set before matching and deleting by VID. This ensures only active VLAN
entries are removed and avoids leaving stale entries in the VLAN filter
table, particularly for VLAN ID 0.

Instead of reading the ZL_REG_REF_MON_STATUS register every time
the reference status is needed, cache this value in the zl3073x_ref
struct.
This is achieved by:
* Adding a mon_status field to struct zl3073x_ref
* Introducing zl3073x_dev_ref_status_update() to read the status for
all references into this new cache field
* Calling this update function from the periodic work handler
* Adding zl3073x_ref_is_status_ok() and zl3073x_dev_ref_is_status_ok()
helpers to check the cached value
* Refactoring all callers in dpll.c to use the new
zl3073x_dev_ref_is_status_ok() helper, removing direct register reads
This change consolidates all status register reads into a single periodic
function and reduces I/O bus traffic in dpll callbacks.

Refactor the zl3073x driver by splitting the logic for input
references, outputs and synthesizers out of the monolithic
core.[ch] files.
Move the logic for each functional block into its own dedicated files:
ref.[ch], out.[ch] and synth.[ch].
Specifically:
- Move state structures (zl3073x_ref, zl3073x_out, zl3073x_synth)
from core.h into their respective new headers
- Move state-fetching functions (..._state_fetch) from core.c to their
new .c files
- Move the zl3073x_ref_freq_factorize helper from core.c to ref.c
- Introduce a new helper layer to decouple the core device logic from
the state-parsing logic:
1. Move the original inline helpers (e.g., zl3073x_ref_is_enabled)
to the new headers (ref.h, etc.) and make them operate on a
const struct ... * pointer.
2. Create new zl3073x_dev_... prefixed functions in core.h
(e.g., zl3073x_dev_ref_is_enabled) and Implement these _dev_ functions
to fetch state using a new ..._state_get() helper and then call
the non-prefixed helper.
3. Update all driver-internal callers (in dpll.c, prop.c, etc.) to use
the new zl3073x_dev_... functions.

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.

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.

The "phy-mode" property of devicetree indicates whether the PCB has
delay now, which means the mac needs to modify the PHY mode based

This modification is similar for many ethernet drivers. To simplify

mac_rxid) to fix PHY mode based on whether mac adds internal delay.

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.

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.

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.

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.

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.

With the MPTCP selftests, the nstat daemon is not used. It means that
the last column (the rate) is always 0.0, and that's not something
interesting to display.
Then, this last column can be filtered out.

net.ipv4.tcp_comp_sack_slack_ns current default value is too high.
When a flow has many drops (1 % or more), and small RTT, adding 100 usec
before sending SACK stalls the sender relying on getting SACK
fast enough to keep the pipe busy.
Decrease the default to 10 usec.
This is orthogonal to Congestion Control heuristics to determine
if drops are caused by congestion or not.

This code was added with 34b31da486a5 ("phy: fixed_phy: Set supported
speed in phydev") 10 yrs ago. The commit message of this change
mentions a use case involving callback adjust_link of struct
dsa_switch_driver. This struct doesn't exist any longer, and in general
usage of the legacy fixed PHY has been removed from DSA with the switch
to phylink.
Note: Supported and advertised modes are now set by phy_probe() when
the fixed PHY is attached to the netdev and bound to the genphy driver.

fbnic supports pause frames. When pause frames are enabled presumably
user expects lossless operation from the NIC. Make sure we configure
RDE (Rx DMA Engine) to DROP_NEVER mode to avoid discards due to delays
in fetching Rx descriptors from the host.
While at it enable DROP_NEVER when NIC only has a single queue
configured. In this case the NIC acts as a FIFO so there's no risk
of head-of-line blocking other queues by making RDE wait. If pause
is disabled this just moves the packet loss from the DMA engine to
the Rx buffer.
Remove redundant call to fbnic_config_drop_mode_rcq(), introduced by
commit 0cb4c0a13723 ("eth: fbnic: Implement Rx queue
alloc/start/stop/free"). This call does not add value as
fbnic_enable_rcq(), which is called immediately afterward, already
handles this.
Although we do not support autoneg at this time, preserve tx_pause in
.mac_link_up instead of fbnic_phylink_get_pauseparam()

Commit 84eaf4359c36 ("net: ethtool: add get_rx_ring_count callback to
optimize RX ring queries") added specific support for GRXRINGS callback,
simplifying .get_rxnfc.
Remove the handling of GRXRINGS in .get_rxnfc() by moving it to the new
.get_rx_ring_count() for both the mlx5 ethernet and IPoIB drivers.
The ETHTOOL_GRXRINGS handling was previously kept in .get_rxnfc() to
support "ethtool -x" when CONFIG_MLX5_EN_RXNFC=n. With the new
dedicated .get_rx_ring_count() callback, this is no longer necessary.
This simplifies the RX ring count retrieval and aligns mlx5 with the new
ethtool API for querying RX ring parameters.
