At present, mlx5 driver have a general purpose
event handler which not only handles vhca event
but also many other events. This incurs a huge
bottleneck because the event handler is
implemented by single threaded workqueue and all
events are forced to be handled in serial manner
even though application tries to create multiple
SFs simultaneously.
Introduce a dedicated vhca event handler which
manages SFs parallel creation.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
This patch eliminates three uses of strncpy():
Firstly, `dest` is expected to be NUL-terminated which is evident by the
manual setting of a NUL-byte at size - 1. For this use specifically,
strscpy() is a viable replacement due to the fact that it guarantees
NUL-termination on the destination buffer.
The next two cases should simply be memcpy() as the size of the src
string is always 3 and the destination string just wants the first 3
bytes changed.
To be clear, there are no buffer overread bugs in the current code as
the sizes and offsets are carefully managed such that buffers are
NUL-terminated. However, with these changes, the code is now more robust
and less ambiguous (and hopefully easier to read).

In very rare cases (I've seen two reports so far about different
RTL8125 chip versions) it seems the MAC locks up when link goes down
and requires a software reset to get revived.
Realtek doesn't publish hw errata information, therefore the root cause
is unknown. Realtek vendor drivers do a full hw re-initialization on
each link-up event, the slimmed-down variant here was reported to fix
the issue for the reporting user.
It's not fully clear which parts of the NIC are reset as part of the
software reset, therefore I can't rule out side effects.

Enable the attachment of a dynamic target to the target created during
boot time. The boot-time targets are named as "cmdline\d", where "\d" is
a number starting at 0.
If the user creates a dynamic target named "cmdline0", it will attach to
the first target created at boot time (as defined in the
`netconsole=...` command line argument). `cmdline1` will attach to the
second target and so forth.
If there is no netconsole target created at boot time, then, the target
name could be reused.

That is not a problem because it is not used inside configfs.

Move alloc_param_target() and its counterpart (free_param_target())
to the bottom of the file. These functions are called mostly at
initialization/cleanup of the module, and they should be just above the
callers, at the bottom of the file.
From a practical perspective, having alloc_param_target() at the bottom
of the file will avoid forward declaration later (in the following
patch).
Nothing changed other than the functions location.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
`desc` is expected to be NUL-terminated as evident by the manual
NUL-byte assignment. Moreover, NUL-padding does not seem to be
necessary.
The only caller of efx_mcdi_nvram_metadata() is
efx_devlink_info_nvram_partition() which provides a NULL for `desc`:
| rc = efx_mcdi_nvram_metadata(efx, partition_type, NULL, version, NULL, 0);
Due to this, I am not sure this code is even reached but we should still
favor something other than strncpy.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

the fact that it guarantees NUL-termination on the destination buffer

Let's also opt to use the more idiomatic strscpy() usage of (dest, src,
sizeof(dest)) rather than (dest, src, SOME_LEN).
Typically the pattern of 1) allocate memory for string, 2) copy string
into freshly-allocated memory is a candidate for kmemdup_nul() but in
this case we are allocating the entirety of the `res` struct and that
should stay as is. As mentioned above, simple 1:1 replacement of strncpy
-> strscpy :)

attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and
fixed manually.

Currently, clock configuration is spread throughout the driver and
partially duplicated for the STM32MP1 and STM32 MCU variants. This makes
it difficult to keep track of which clocks need to be enabled or disabled
in various scenarios.
This patch adds symmetric stm32_dwmac_clk_enable/disable() functions
that handle all clock configuration, including quirks required while
suspending or resuming. syscfg_clk and clk_eth_ck are not present on
STM32 MCUs, but it is fine to try to configure them anyway since NULL
clocks are ignored.

Add support for flush VXLAN FDB entries by destination IP. FDB entry is
stored as {MAC, SRC_VNI} + remote. The destination IP is an attribute of
the remote. For multicast entries, the VXLAN driver stores a linked list
of remotes for a given key.
In user space, each remote is represented as a separate entry, so when
flush is sent with filter of 'destination IP', flush only the match
remotes. In case that there are no additional remotes, destroy the entry.
For example, the following are stored as one entry with several remotes:
$ bridge fdb show dev vx10
00:00:00:00:00:00 dst 192.1.1.3 self permanent
00:00:00:00:00:00 dst 192.1.1.1 self permanent
00:00:00:00:00:00 dst 192.1.1.2 self permanent
00:00:00:00:00:00 dst 192.1.1.1 vni 1000 self permanent
When user flush by destination IP x, only the relevant remotes will be
flushed:
$ bridge fdb flush dev vx10 dst 192.1.1.1
$ bridge fdb show dev vx10
00:00:00:00:00:00 dst 192.1.1.3 self permanent

The merge commit 92716869375b ("Merge branch 'br-flush-filtering'")
added support for FDB flushing in bridge driver only, the VXLAN driver does
not support such flushing. Extend VXLAN driver to support FDB flushing.
In this commit, add support for flushing with state and flags, which are
the fields that supported in the bridge driver.
Note that bridge driver supports 'NTF_USE' flag, but there is no point to
support this flag for flushing as it is ignored when flags are stored.
'NTF_STICKY' is not relevant for VXLAN driver.
'NTF_ROUTER' is not supported in bridge driver for flush as it is not
relevant for bridge, add it for VXLAN.

Currently, the function vxlan_flush() does not flush the default FDB entry
(an entry with all_zeros_mac and default VNI), as it is deleted at
vxlan_uninit(). When this function will be used for flushing FDB entries
from user space, it will have to flush also the default entry in case that
other parameters match (e.g., VNI, flags).
Extend 'struct vxlan_fdb_flush_desc' to include an indication whether
the default entry should be flushed or not. The default value (false)
indicates to flush it, adjust all the existing callers to set
'.ignore_default_entry' to true, so the current behavior will not be
changed.

The function vxlan_flush() gets a boolean called 'do_all' and in case
that it is false, it does not flush entries with state 'NUD_PERMANENT'
or 'NUD_NOARP'. The following patches will add support for FDB flush
with parameters from user space. Make the function more generic, so it
can be used later.

mt8195 platform that had been pending for a while.
On the ixp4xx platform, Krzysztof Halasa steps down as co-maintainer,
reflecting that Linus Walleij has been handling this on his own for
the past few years.
Generic RISC-V kernels are now marked as incompatible with the RZ/Five
platform that requires custom hacks both for managing its DMA bounce
buffers and for addressing low virtual memory.
Finally, there is one bugfix for the AMDTEE firmware driver to prevent
a use-after-free bug"
