Kernel configs don't necessarily have opcode decoding, and some opcodes
are not even decodable. It is still interesting for debugging SSD issues
to know what opcode is timing out, what request type it came from, and
the data size (if applicable).
Also print the command_id along side blk-mq's tag to help match commands
with protocol wire traces and firmware logs,

Currently, if the function irq_domain_add_linear() fails to allocate
a new IRQ domain and returns NULL, we would then still return a success
from the xilinx_pl_dma_pcie_init_irq_domain() function regardless, as
the PTR_ERR(NULL) would return a value of zero. This is not a desirable
outcome.
Thus, fix the incorrect error code and return the -ENOMEM error code if
the irq_domain_add_linear() fails to allocate a new IRQ domain.

Through hidraw, userspace can cause a status report to be sent
from the device. The parsing in waterforce_raw_event() may happen in
parallel to a waterforce_get_status() call (which resets the completion
for tracking the report) if it's running on a different CPU where
bottom half interrupts are not disabled.
Add a spinlock around the complete_all() call in waterforce_raw_event()
to prevent race issues.

Merge system-wide power management updates for 6.8-rc1:
- Fix possible deadlocks in the core system-wide PM code that occur if
device-handling functions cannot be executed asynchronously during
resune from system-wide suspend (Rafael J. Wysocki).
- Clean up unnecessary local variable initializations in multiple
places in the hibernation code (Wang chaodong, Li zeming).

occur after saving an image to persistent storage (Chris Feng).
- Update hibernation code to enforce correct ordering during image
compression and decompression (Hongchen Zhang).

While frontends may submit zero-size requests (wasting a precious slot),
core networking code as of at least 3ece782693c4b ("sock: skb_copy_ubufs
support for compound pages") can't deal with SKBs when they have all
zero-size fragments. Respond to empty requests right when populating
fragments; all further processing is fragment based and hence won't
encounter these empty requests anymore.
In a way this should have been that way from the beginning: When no data
is to be transferred for a particular request, there's not even a point
in validating the respective grant ref. That's no different from e.g.
passing NULL into memcpy() when at the same time the size is 0.
This is XSA-448 / CVE-2023-46838.

Some legacy devices have configuration ROM against standard AV/C device.
They have vendor directory to store model identifier. It is described in
annex of the following document.
- Configuration ROM for AV/C Devices 1.0 (Dec. 12, 2000, 1394 Trading
Association)
In the case, current implementation of core function does not detect the
model identifier, thus device attributes and modalias of unit have lack of
it. Another KUnit test is required for the case, and this commit is for
the purpose.
The following output is the parse result for the hard-coded data, by
config-rom-pretty-printer in linux-firewire-utils
(https://git.kernel.org/pub/scm/utils/ieee1394/linux-firewire-utils.git/).
The data is written by my hand.

In IEEE 1394 specification, the size of bus information block of
configuration ROM is fixed to 5, thus the offset of root directory is 5.
Current implementation to handle device structures has the hard-coded
offset.

As per the Cadence IP document fixed the I2C clock divider value limit from
16 bits instead of 10 bits. Without this change setting up the I2C clock to
low frequencies will not work as the prescaler value might be greater than
10 bit number.
I3C clock divider value is 10 bits only. Updating the macro names for both.

I3C transfer (SDR), target can early terminate read transfer.
I3C transfer (HDR), target can end write transfer.
I2C transfer, target can NACK write transfer.
'actual_len' is better name than 'read_len'.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
This is less verbose.
Note that the upper bound of ida_alloc_range() is inclusive while the one
of ida_simple_get() was exclusive. So calls have been updated accordingly.

The recent change to allow large frames without hardware checksumming
slotted in software checksumming in the driver if hardware could not
do it.
This will however upset TSO (TCP Segment Offloading). Typical
error dumps includes this:
skb len=2961 headroom=222 headlen=66 tailroom=0
(...)
WARNING: CPU: 0 PID: 956 at net/core/dev.c:3259 skb_warn_bad_offload+0x7c/0x108
gemini-ethernet-port: caps=(0x0000010000154813, 0x00002007ffdd7889)
And the packets do not go through.
The TSO implementation is bogus: a TSO enabled driver must propagate
the skb_shinfo(skb)->gso_size value to the TSO engine on the NIC.
Drop the size check and TSO offloading features for now: this
needs to be fixed up properly.
After this ethernet works fine on Gemini devices with a direct connected
PHY such as D-Link DNS-313.
Also tested to still be working with a DSA switch using the Gemini
ethernet as conduit interface.

Fix per-queue statistics for devices with more than one queue.
The output data pointer is currently reset in each loop iteration,
effectively summing all queue statistics in the first four u64 values.
The summary values are not even labeled correctly. For example, if eth0 has
2 queues, ethtool -S eth0 shows:
q0_tx_pkt_n: 374 (actually tx_pkt_n over all queues)
q0_tx_irq_n: 23 (actually tx_normal_irq_n over all queues)
q1_tx_pkt_n: 462 (actually rx_pkt_n over all queues)
q1_tx_irq_n: 446 (actually rx_normal_irq_n over all queues)
q0_rx_pkt_n: 0
q0_rx_irq_n: 0
q1_rx_pkt_n: 0
q1_rx_irq_n: 0

At the moment, the GigE port is enabled in the mlxbf_gige_probe

pause frames to increase in the case where there is high backgroud

So move enabling the OOB port to mlxbf_gige_open.

Although the link is up, there is no ip assigned on setups with high background
traffic. Nothing is transmitted nor received. The RX error count keeps on
increasing. After several minutes, the RX error count stagnates and the
GigE interface finally gets an ip.
The issue is that mlxbf_gige_rx_init() is called before phy_start().
As soon as the RX DMA is enabled in mlxbf_gige_rx_init(), the RX CI reaches the max
of 128, and becomes equal to RX PI. RX CI doesn't decrease since the code hasn't
ran phy_start yet.
Bring the PHY up before starting the RX.
