of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

amt message type definition starts from 1, not 0.
But type_str[] starts from 0.
So, it prints wrong type information.

When amt interface receives amt message, it tries to obtain amt private
data from sock.
If there is no amt private data, it frees an skb immediately.
After kfree_skb(), it increases the rx_dropped stats.
But in order to use rx_dropped, amt private data is needed.
So, it makes amt_rcv() to do not increase rx_dropped stats when it can
not obtain amt private data.

There is a limitation in TI DP83867 PHY device where SGMII AN is only
triggered once after the device is booted up. Even after the PHY TPI is
down and up again, SGMII AN is not triggered and hence no new in-band
message from PHY to MAC side SGMII.
This could cause an issue during power up, when PHY is up prior to MAC.
At this condition, once MAC side SGMII is up, MAC side SGMII wouldn`t
receive new in-band message from TI PHY with correct link status, speed
and duplex info.
As suggested by TI, implemented a SW solution here to retrigger SGMII
Auto-Neg whenever there is a link change.

"Here is the big set of staging driver updates for 5.19-rc1.
Lots of forward progress happened this development cycle, one driver
(wfx wireless driver) got merged into the real portion of the kernel,
and another one (unisys) was removed as no one is around anymore to
take care of it and no one has the hardware. Combined with loads of
tiny driver cleanups overall we removed 13k lines of code from the
tree, a nice improvement.
Other than the wfx and unisys driver changes the major points of this
merge is:
- r8188eu driver cleanups. So many cleanups. It's amazing just how
many things have been cleaned up here, and yet, how many remain to
go. Lots of work happened here, and it doesn't look to slow down
any time soon.
- other wifi driver cleanups. Not as many as the r8188eu driver, but
still pretty impressive from a janitorial point of view.

I have a board where these two lines are always printed during boot:
imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed
It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.
Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.
While here, add the missing \n to one of the format strings.

Global `-Warray-bounds` enablement revealed some problems, one of
which is the way we define and use AQC rules messages.
In fact, they have a shared header, followed by the actual message,
which can be of one of several different formats. So it is
straightforward enough to define that header as a separate struct
and then embed it into message structures as needed, but currently
all the formats reside in one union coupled with the header. Then,
the code allocates only the memory needed for a particular message
format, leaving the union potentially incomplete.
There are no actual reads or writes beyond the end of an allocated
chunk, but at the same time, the whole implementation is fragile and
backed by an equilibrium rather than strong type and memory checks.
Define the structures the other way around: one for the common
header and the rest for the actual formats with the header embedded.
There are no places where several union members would be used at the
same time anyway. This allows to use proper struct_size() and let
the compiler know what is going to be done.
Finally, unsilence `-Warray-bounds` back for ice_switch.c.
Other little things worth mentioning:
* &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's
weird anyway to talk to hardware with purely kernel types
(bitmaps);
* expand the ICE_SW_RULE_*_SIZE() macros to pass a structure
variable name to struct_size() to let it do strict typechecking;
* rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr
for the header structure to have the same name for it constistenly
everywhere;
* drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in
ice_switch.h.

NFDK firmware supports 48-bit dma addressing and
parses 16 high bits of dma addresses.
In nfp_nfdk_tx_desc, dma related structure and tso
related structure are union. When "mss" be filled
with nonzero value due to enable tso, the memory used
by "padding" may be also filled. Then, firmware may
parse wrong dma addresses which causes TX watchdog
timeout problem.
This patch removes padding and unifies the dma_addr_hi
bits with the one in firmware. nfp_nfdk_tx_desc_set_dma_addr
is also added to match this change.

tx_channel_offset is calculated in efx_allocate_msix_channels, but it is
also calculated again in efx_set_channels because it was originally done
there, and when efx_allocate_msix_channels was introduced it was
forgotten to be removed from efx_set_channels.
Moreover, the old calculation is wrong when using
efx_separate_tx_channels because now we can have XDP channels after the
TX channels, so n_channels - n_tx_channels doesn't point to the first TX
channel.
Remove the old calculation from efx_set_channels, and add the
initialization of this variable if MSI or legacy interrupts are used,
next to the initialization of the rest of the related variables, where
it was missing.
This has been already done for sfc, do it also for sfc_siena.

Normally, all channels have RX and TX queues, but this is not true if
modparam efx_separate_tx_channels=1 is used. In that cases, some
channels only have RX queues and others only TX queues (or more
preciselly, they have them allocated, but not initialized).
Fix efx_channel_has_tx_queues to return the correct value for this case
too.
This has been already done for sfc, do it also for sfc_siena.

In some use-cases, mlx5 instances will need to search for their peer
device (the other port on the same HCA). For that, mlx5 device matching
mechanism relied on auxiliary_find_device() to search, and used a bad matching
callback function.
This approach has two issues:
1) next_phys_dev() the matching function, assumed all devices are
of the type mlx5_adev (mlx5 auxiliary device) which is wrong and
could lead to crashes, this worked for a while, since only lately
other drivers started registering auxiliary devices.
2) using the auxiliary class bus (auxiliary_find_device) to search for
mlx5_core_dev devices, who are actually PCIe device instances, is wrong.
This works since mlx5_core always has at least one mlx5_adev instance
hanging around in the aux bus.
As suggested by others we can fix 1. by comparing device names prefixes
if they have the string "mlx5_core" in them, which is not a best practice !
but even with that fixed, still 2. needs fixing, we are trying to
match pcie device peers so we should look in the right bus (pci bus),
hence this fix.
The fix:
1) search the pci bus for mlx5 peer devices, instead of the aux bus
2) to validated devices are the same type "mlx5_core_dev" compare if
they have the same driver, which is bulletproof.
This wouldn't have worked with the aux bus since the various mlx5 aux
device types don't share the same driver, even if they share the same device
wrapper struct (mlx5_adev) "which helped to find the parent device"

Some features (LRO, HW GRO) conflict with XDP. If there is an attempt to
enable such features while XDP is active, they will be set to `off

When the driver activates the channels, it assumes NAPI isn't running
yet. mlx5e_activate_rq posts a NOP WQE to ICOSQ to trigger a hardware
interrupt and start NAPI, which will run mlx5e_alloc_rx_mpwqe and post
UMR WQEs to ICOSQ to be able to receive packets with striding RQ.
Unfortunately, a race condition is possible if NAPI is triggered by
something else (for example, TX) at a bad timing, before
mlx5e_activate_rq finishes. In this case, mlx5e_alloc_rx_mpwqe may post
UMR WQEs to ICOSQ, and with the bad timing, the wqe_info of the first
UMR may be overwritten by the wqe_info of the NOP posted by
mlx5e_activate_rq.
The consequence is that icosq->db.wqe_info[0].num_wqebbs will be changed
from MLX5E_UMR_WQEBBS to 1, disrupting the integrity of the array-based
linked list in wqe_info[]. mlx5e_poll_ico_cq will hang in an infinite
loop after processing wqe_info[0], because after the corruption, the
next item to be processed will be wqe_info[1], which is filled with
zeros, and `sqcc += wi->num_wqebbs` will never move further.
This commit fixes this race condition by using async_icosq to post the
NOP and trigger the interrupt. async_icosq is always protected with a
spinlock, eliminating the race condition.

The cited commit changed promisc table to be created on demand with the
highest priority in the NIC table replacing the vlan table, this caused
tc NIC tables miss flow to skip the prmoisc table because it use vlan
table as miss table.
OVS offload in NIC mode use promisc by default so any unicast packet
which will be handled by tc NIC tables miss flow will skip the promisc
rule and will be dropped.
Fix this by adding new empty table in new tc level with low priority and
point the nic tc chain miss to it, the new table is managed so it will
point to vlan table if promisc is disabled and to promisc table if enabled.

Before 7beecaf7d507b ("net: phy: at803x: improve the WOL feature") patch
"at803x_get_wol" implementation used AT803X_INTR_ENABLE_WOL value to set
WAKE_MAGIC flag, and now AT803X_WOL_EN value is used for the same purpose.
The problem here is that the values of these two bits are different after
hardware reset: AT803X_INTR_ENABLE_WOL=0 after hardware reset, but
AT803X_WOL_EN=1. So now, if called right after boot, "at803x_get_wol" will
set WAKE_MAGIC flag, even if WOL function is not enabled by calling
"at803x_set_wol" function. The patch disables WOL function on probe thus
the behavior is consistent.

The firmware has a 512 limit here, but we use less, so gcc
starts complaining about it:
drivers/net/wireless/marvell/libertas/cfg.c:1198:63: warning: array subscript ‘struct cmd_ds_802_11_associate_response[0]’ is partly outside array bounds of ‘unsigned char[203]’ [-Warray-bounds]
1198 | "aid 0x%04x\n", status, le16_to_cpu(resp->statuscode),
| ^~
Since we size the command and response buffer per our needs
and not per the firmware maximum, change to a variable size
data array and put the 512 only into a comment.
In the end, that's actually what the code always wanted, and
it simplifies the code that used to subtract the fixed size
buffer size in two places.

tx_channel_offset is calculated in efx_allocate_msix_channels, but it is
also calculated again in efx_set_channels because it was originally done
there, and when efx_allocate_msix_channels was introduced it was
forgotten to be removed from efx_set_channels.
Moreover, the old calculation is wrong when using
efx_separate_tx_channels because now we can have XDP channels after the
TX channels, so n_channels - n_tx_channels doesn't point to the first TX
channel.
Remove the old calculation from efx_set_channels, and add the
initialization of this variable if MSI or legacy interrupts are used,
next to the initialization of the rest of the related variables, where
it was missing.

Normally, all channels have RX and TX queues, but this is not true if

channels only have RX queues and others only TX queues (or more
preciselly, they have them allocated, but not initialized).

too.

of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
mv88e6xxx_mdio_register() pass the device node to of_mdiobus_register().
We don't need the device node after it.
Add missing of_node_put() to avoid refcount leak.

of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
am65_cpsw_init_cpts() and am65_cpsw_nuss_probe() don't release
the refcount in error case.
Add missing of_node_put() to avoid refcount leak.

The "fsp->location" variable comes from user via ethtool_get_rxnfc().
Check that it is valid to prevent an out of bounds read.
