For non WoW suspend/resume, ath11k host powers down whole hardware
when suspend and powers up it when resume, the code path it goes
through is very like the ath11k reset logic.
In order to reuse that logic, rearrange IRQ handling in the reset
path.

Through the routine bond_mii_monitor(), bonding driver inspects and commits
the slave state changes. During the times when slave state change and
failure in aqcuiring rtnl lock happen at the same time, the routine
bond_mii_monitor() reschedules itself to come around after 1 msec to commit
the new state.
During this, it executes the routine bond_miimon_inspect() to re-inspect
the state chane and prints the corresponding slave state on to the console.
Hence we do see a message at every 1 msec till the rtnl lock is acquired
and state chage is committed.
This patch doesn't change how bond functions. It only simply limits this
kind of log flood.

====================
netfilter updates for net-next
1. Prefer KMEM_CACHE() macro to create kmem caches, from Kunwu Chan.
Patches 2 and 3 consolidate nf_log NULL checks and introduces
extra boundary checks on family and type to make it clear that no out
of bounds access will happen. No in-tree user currently passes such
values, but thats not clear from looking at the function.
From Pablo Neira Ayuso.
Patch 4, also from Pablo, gets rid of unneeded conditional in
nft_osf init function.
Patch 5, from myself, fixes erroneous Kconfig dependencies that
came in an earlier net-next pull request. This should get rid
of the xtables related build failure reports.
Patches 6 to 10 are an update to nftables' concatenated-ranges
set type to speed up element insertions. This series also
compacts a few data structures and cleans up a few oddities such
as reliance on ZERO_SIZE_PTR when asking to allocate a set with
no elements. From myself.
Patches 11 moves the nf_reinject function from the netfilter core
(vmlinux) into the nfnetlink_queue backend, the only location where
this is called from. Also from myself.
Patch 12, from Kees Cook, switches xtables' compat layer to use
unsafe_memcpy because xt_entry_target cannot easily get converted
to a real flexible array (its UAPI and used inside other structs).

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the ipv6/sit driver and leverage the network
core allocation.

Pull tracing fix from Steven Rostedt:
- While working on the ring buffer I noticed that the counter used for
knowing where the end of the data is on a sub-buffer was not a full
"int" but just 20 bits. It was masked out to 0xfffff.
With the new code that allows the user to change the size of the
sub-buffer, it is theoretically possible to ask for a size bigger
than 2^20. If that happens, unexpected results may occur as there's
no code checking if the counter overflowed the 20 bits of the write
mask. There are other checks to make sure events fit in the
sub-buffer, but if the sub-buffer itself is too big, that is not
checked.
Add a check in the resize of the sub-buffer to make sure that it
never goes beyond the size of the counter that holds how much data is
on it.

====================
bnxt_en: Ntuple filter improvements
The current Ntuple filter implementation has a limitation on 5750X (P5)
and newer chips. The destination ring of the ntuple filter must be
a valid ring in the RSS indirection table. Ntuple filters may not work
if the RSS indirection table is modified by the user to only contain a
subset of the rings. If an ntuple filter is set to a ring destination
that is not in the RSS indirection table, the packet matching that
filter will be placed in a random ring instead of the specified
destination ring.
This series of patches will fix the problem by using a separate VNIC
for ntuple filters. The default VNIC will be dedicated for RSS and
so the indirection table can be setup in any way and will not affect
ntuple filters using the separate VNIC.
Quite a bit of refactoring is needed to do the the VNIC and RSS
context accounting in the first few patches. This is technically a
bug fix, but I think the changes are too big for -net.

Allocate and setup the additional VNIC for ntuple filters if this
new method is supported by the firmware. Even though this VNIC is
only used for ntuple filters with direct ring destinations, we still
setup the RSS hash to be identical to the default VNIC so that each
RX packet will have the correct hash in the RX completion. This
VNIC is always at VNIC index BNXT_VNIC_NTUPLE.

On newer chips that support the ring table index method for
ntuple filters, the current scheme of using the same VNIC for
both RSS and ntuple filters will not work in all cases. An
ntuple filter can only be directed to a destination ring if
that destination ring is also in the RSS indirection table.
To support ntuple filters with any arbitratry RSS indirection
table that may only include a subset of the rings, we need to
use a separate VNIC for ntuple filters.
This patch provisions the additional VNIC. The next patch will
allocate additional VNIC from firmware and set it up.

bnxt_check_rings() is called to check if we have enough resource
assets to satisfy the new number of ethtool channels. If the asset
test fails, the ethtool operation will fail gracefully. Otherwise
we will proceed and commit to use the new number of channels. If it
fails to allocate any resources, the chip will fail to come up.
For completeness, check all possible resources before committing to
the new settings. Add the missing ring group and RSS context asset

With these, we can now specific the exact number of RSS contexts to

reserved value is not stored. This improved infrastructure will make

When CONFIG_MCTP_FLOWS is enabled, outgoing skbs should have their
SKB_EXT_MCTP extension set for drivers to consume.
Add two tests for local-to-output routing that check for the flow
extensions: one for the simple single-packet case, and one for
fragmentation.
We now make MCTP_TEST select MCTP_FLOWS, so we always get coverage of
these flow tests. The tests are skippable if MCTP_FLOWS is (otherwise)
disabled, but that would need manual config tweaking.

l2tp_ip6_sendmsg needs to avoid accounting for the transport header
twice when splicing more data into an already partially-occupied skbuff.
To manage this, we check whether the skbuff contains data using
skb_queue_empty when deciding how much data to append using
ip6_append_data.
However, the code which performed the calculation was incorrect:
ulen = len + skb_queue_empty(&sk->sk_write_queue) ? transhdrlen : 0;
...due to C operator precedence, this ends up setting ulen to
transhdrlen for messages with a non-zero length, which results in
corrupted packets on the wire.
Add parentheses to correct the calculation in line with the original
intent.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) If user requests to wake up a table and hook fails, restore the
dormant flag from the error path, from Florian Westphal.
2) Reset dst after transferring it to the flow object, otherwise dst
gets released twice from the error path.
3) Release dst in case the flowtable selects a direct xmit path, eg.
transmission to bridge port. Otherwise, dst is memleaked.
4) Register basechain and flowtable hooks at the end of the command.
Error path releases these datastructure without waiting for the
rcu grace period.
5) Use kzalloc() to initialize struct nft_hook to fix a KMSAN report
on access to hook type, also from Florian Westphal.

The variable tidno is being assigned a value that is not being read
and is being re-assigned a new value a few statements later.
The assignment is redundant and can be removed.

Because the number of channels to be configured is calculated using the %,
and it results in 0 when there's an exact division, this leads to some
channels not having their tx power configured.

MediaTek's controller driver on COB platform (e.g. MT8188) is
capable of controlling power supplies and reset pin of a component
(e.g. a WIFI chip) in power-on and power-off process.
Due to this optional feature, mt76 need to inform controller
that mt76 need to keep power during suspend. Otherwise WIFI will be
powered off when system enters suspend process.
The "wakeup-source" property was used for the device that need
this to go into suspend mode so that mt76 suspend handler doesn't
fail and the system is able to enter into a suspend state.
An example:
wifi: mt7921@0 {
wifi0{
reg = <0x0000 0 0 0 0>;
wakeup-source;
};
};

to make sure the shared irq handler should be able to handle the unexpected

indicate the device was removed and do not run into the resource access
anymore.
