Linux LEDs can be requested to perform hardware accelerated blinking
to indicate link, RX, TX etc. Pass the rules for blinking to the PHY
driver, if it implements the ops needed to determine if a given
pattern can be offloaded, to offload it, and what the current offload
is. Additionally implement the op needed to get what device the LED is
for.

When using a fixed-link setup, certain devices like the SJA1105 require a
small pause in the TXC clock line to enable their internal tunable
delay line (TDL).
To satisfy this requirement, this patch temporarily disables the TX clock,
and restarts it after a required period. This provides the required
silent interval on the clock line for SJA1105 to complete the frequency
transition and enable the internal TDLs. This action occurs before the link
is built up, so it does not impact a normal device too. There is no
need to identify if the connected device is an SJA1105 alike or not during
the implementation.
So far we have only enabled this feature on the i.MX93 platform.

Kernel uses `struct virtio_net_ctrl_rss` to save command-specific-data
for both the VIRTIO_NET_CTRL_MQ_HASH_CONFIG and
VIRTIO_NET_CTRL_MQ_RSS_CONFIG commands.
According to the VirtIO standard, "Field reserved MUST contain zeroes.
It is defined to make the structure to match the layout of
virtio_net_rss_config structure, defined in 5.1.6.5.7.".
Yet for the VIRTIO_NET_CTRL_MQ_HASH_CONFIG command case, the `max_tx_vq`
field in struct virtio_net_ctrl_rss, which corresponds to the
`reserved` field in struct virtio_net_hash_config, is not zeroed,
thereby violating the VirtIO standard.
This patch solves this problem by zeroing this field in
virtnet_init_default_rss().

hns3_dbg_fill_content()/hclge_dbg_fill_content() is aim to integrate some
items to a string for content, and we add '\n' and '\0' in the last
two bytes of content.
strscpy() will add '\0' in the last byte of destination buffer(one of
items), it result in finishing content print ahead of schedule and some
dump content truncation.
One Error log shows as below:
cat mac_list/uc
UC MAC_LIST:
Expected:
UC MAC_LIST:
FUNC_ID MAC_ADDR STATE
pf 00:2b:19:05:03:00 ACTIVE
The destination buffer is length-bounded and not required to be
NUL-terminated, so just change strscpy() to memcpy() to fix it.

If a login request fails, the recovery process should be protected
against parallel resets. It is a known issue that freeing and
registering CRQ's in quick succession can result in a failover CRQ from
the VIOS. Processing a failover during login recovery is dangerous for
two reasons:
1. This will result in two parallel initialization processes, this can
cause serious issues during login.
2. It is possible that the failover CRQ is received but never executed.
We get notified of a pending failover through a transport event CRQ.
The reset is not performed until a INIT CRQ request is received.
Previously, if CRQ init fails during login recovery, then the ibmvnic
irq is freed and the login process returned error. If failover_pending
is true (a transport event was received), then the ibmvnic device
would never be able to process the reset since it cannot receive the
CRQ_INIT request due to the irq being freed. This leaved the device
in a inoperable state.
Therefore, the login failure recovery process must be hardened against
these possible issues. Possible failovers (due to quick CRQ free and
init) must be avoided and any issues during re-initialization should be
dealt with instead of being propagated up the stack. This logic is
similar to that of ibmvnic_probe().

Perform a partial reset before sending a login request if any of the
following are true:
1. If a previous request times out. This can be dangerous because the
VIOS could still receive the old login request at any point after
the timeout. Therefore, it is best to re-register the CRQ's and
sub-CRQ's before retrying.
2. If the previous request returns an error that is not described in
PAPR. PAPR provides procedures if the login returns with partial
success or aborted return codes (section L.5.1) but other values
do not have a defined procedure. Previously, these conditions
just returned error from the login function rather than trying
to resolve the issue.
This can cause further issues since most callers of the login
function are not prepared to handle an error when logging in. This
improper cleanup can lead to the device being permanently DOWN'd.
For example, if the VIOS believes that the device is already logged
in then it will return INVALID_STATE (-7). If we never re-register
CRQ's then it will always think that the device is already logged
in. This leaves the device inoperable.
The partial reset involves freeing the sub-CRQs, freeing the CRQ then
registering and initializing a new CRQ and sub-CRQs. This essentially
restarts all communication with VIOS to allow for a fresh login attempt
that will be unhindered by any previous failed attempts.

Rather than leaving the DMA unmapping of the login buffers to the
login response handler, move this work into the login release functions.
Previously, these functions were only used for freeing the allocated
buffers. This could lead to issues if there are more than one
outstanding login buffer requests, which is possible if a login request
times out.
If a login request times out, then there is another call to send login.
The send login function makes a call to the login buffer release
function. In the past, this freed the buffers but did not DMA unmap.
Therefore, the VIOS could still write to the old login (now freed)
buffer. It is for this reason that it is a good idea to leave the DMA
unmap call to the login buffers release function.
Since the login buffer release functions now handle DMA unmapping,
remove the duplicate DMA unmapping in handle_login_rsp().

Ensure that all offsets in a login response buffer are within the size
of the allocated response buffer. Any offsets or lengths that surpass
the allocation are likely the result of an incomplete response buffer.
In these cases, a full reset is necessary.
When attempting to login, the ibmvnic device will allocate a response
buffer and pass a reference to the VIOS. The VIOS will then send the
ibmvnic device a LOGIN_RSP CRQ to signal that the buffer has been filled
with data. If the ibmvnic device does not get a response in 20 seconds,
the old buffer is freed and a new login request is sent. With 2
outstanding requests, any LOGIN_RSP CRQ's could be for the older
login request. If this is the case then the login response buffer (which
is for the newer login request) could be incomplete and contain invalid
data. Therefore, we must enforce strict sanity checks on the response
buffer values.
Testing has shown that the `off_rxadd_buff_size` value is filled in last
by the VIOS and will be the smoking gun for these circumstances.
Until VIOS can implement a mechanism for tracking outstanding response
buffers and a method for mapping a LOGIN_RSP CRQ to a particular login
response buffer, the best ibmvnic can do in this situation is perform a
full reset.

When unloading the MANA driver, mana_dealloc_queues() waits for the MANA
hardware to complete any inflight packets and set the pending send count
to zero. But if the hardware has failed, mana_dealloc_queues()
could wait forever.
Fix this by adding a timeout to the wait. Set the timeout to 120 seconds,
which is a somewhat arbitrary value that is more than long enough for
functional hardware to complete any sends.

accept ndo_setup_tc(TC_SETUP_QDISC_TAPRIO) calls.

I'd like to make netdevsim offload tc-taprio, but currently, this Qdisc
emits a ETHTOOL_GET_TS_INFO call to the driver to make sure that it has
a PTP clock, so that it is reasonably capable of offloading the schedule.
By using the mock PHC driver, that becomes possible.
Hardware timestamping is not necessary, and netdevsim does not support

Expose NIC temperature by implementing hwmon kernel API, which turns
current thermal zone kernel API to redundant.
For each one of the supported and exposed thermal diode sensors, expose
the following attributes:
1) Input temperature.
2) Highest temperature.
3) Temperature label:
Depends on the firmware capability, if firmware doesn't support
sensors naming, the fallback naming convention would be: "sensorX",
where X is the HW spec (MTMP register) sensor index.
4) Temperature critical max value:
refers to the high threshold of Warning Event. Will be exposed as
`tempY_crit` hwmon attribute (RO attribute). For example for
ConnectX5 HCA's this temperature value will be 105 Celsius, 10
degrees lower than the HW shutdown temperature).
5) Temperature reset history: resets highest temperature.
For example, for dualport ConnectX5 NIC with a single IC thermal diode
sensor will have 2 hwmon directories (one for each PCI function)
under "/sys/class/hwmon/hwmon[X,Y]".
Listing one of the directories above (hwmonX/Y) generates the
corresponding output below:
$ grep -H -d skip . /sys/class/hwmon/hwmon0/*
Output

track of it as a bridge port. The bridge_port's STP state is initialized to
BR_STATE_DISABLED. This made sense previously, because mlxsw would only
ever allow a port to join a LAG if the LAG had no uppers. Thus if a
bridge_port was instantiated, it must have been because the LAG as such is
joining a bridge, and the STP state is correspondingly disabled.
However as of commit 2c5ffe8d7226 ("mlxsw: spectrum: Permit enslavement to
netdevices with uppers"), mlxsw allows a port to join a LAG that is already
a member of a bridge. The STP state may be different than disabled in that
case. Initialize it properly by querying the actual state.
This bug may cause an issue as traffic on ports attached to a bridged LAG
gets dropped on ingress with discard_ingress_general counter bumped.

If cfg80211 is providing extraie's for a scanning process then ath12k will
copy that over to the firmware. The extraie.len is a 32 bit value in struct
element_info and describes the amount of bytes for the vendor information
elements.
The problem is the allocation of the buffer. It has to align the TLV
sections by 4 bytes. But the code was using an u8 to store the newly
calculated length of this section (with alignment). And the new
calculated length was then used to allocate the skbuff. But the actual
code to copy in the data is using the extraie.len and not the calculated
"aligned" length.
The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled
was 264 bytes during tests with a wifi card. But it only allocated 8
bytes (264 bytes % 256) for it. As consequence, the code to memcpy the
extraie into the skb was then just overwriting data after skb->end. Things
like shinfo were therefore corrupted. This could usually be seen by a crash
in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus
address).

Wireless USB has long been defunct, and kernel support for it was
removed in 2020 by commit caa6772db4c1 ("Staging: remove wusbcore and
UWB from the kernel tree.").
Nevertheless, some vestiges of the old implementation still clutter up
the USB subsystem and one or two other places. Let's get rid of them
once and for all.
The only parts still left are the user-facing APIs in
include/uapi/linux/usb/ch9.h. (There are also a couple of misleading
instances, such as the Sierra Wireless USB modem, which is a USB modem
made by Sierra Wireless.)

Access to the connection tracking table in EF100 hardware is through
a "generic" table mechanism, whereby a firmware call at probe time
gives the driver a description of the field widths and offsets, so
that the driver can then construct key and response bitstrings at
runtime.
Probe the NIC for this information and populate the needed metadata
into a new meta_ct field of struct efx_tc_state.

Rob's suggestion is to reimplement the enetc driver workaround as a
PCI fixup, and to modify the PCI core to run the fixups for all PCI
functions. This change handles the first part.
We refactor the common code in enetc_psi_create() and enetc_psi_destroy(),
and use the PCI fixup only for those functions for which enetc_pf_probe()
won't get called. This avoids some work being done twice for the PFs
which are enabled.

Add fdir_fltr_lock locking in unprotected places.
The change in iavf_fdir_is_dup_fltr adds a spinlock around a loop which
iterates over all filters and looks for a duplicate. The filter can be
removed from list and freed from memory at the same time it's being
compared. All other places where filters are deleted are already
protected with spinlock.
The remaining changes protect adapter->fdir_active_fltr variable so now
all its uses are under a spinlock.
