ENA Express metrics, called `ena_srd` are exposed to
customers via `ethtool`.
The metrics allow customers to check the configuration
(mode), tx/rx counters as well as resource utilization.
The documentation is also updated to provide a general
explanation about ENA Express as well as links for further
information about metrics and configurations.

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects. Although
that is not the case here, it is seems best to use ';' unless ',' is
intended.

During system resume, sd_start_stop_device() submits a START STOP UNIT
command to the SCSI device that is being resumed. That command is not
retried in case of a unit attention and hence may fail. An example:
[16575.983359] sd 0:0:0:3: [sdd] Starting disk
[16575.983693] sd 0:0:0:3: [sdd] Start/Stop Unit failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK
[16575.983712] sd 0:0:0:3: [sdd] Sense Key : 0x6
[16575.983730] sd 0:0:0:3: [sdd] ASC=0x29 ASCQ=0x0
[16575.983738] sd 0:0:0:3: PM: dpm_run_callback(): scsi_bus_resume+0x0/0xa0 returns -5
[16575.983783] sd 0:0:0:3: PM: failed to resume async: error -5
Make the SCSI core retry the START STOP UNIT command if the device reports
that it has been powered on or that it has been reset.

Commit 0c52310f2600 ("hrtimer: Ignore slack time for RT tasks in
schedule_hrtimeout_range()") effectivelly shortens a sleep in a polling
function in the driver. That is causing a performance regression as the
new value of just 2us is too low, in certain tests the perf drop is ~30%.
Fix this by adjusting the sleep to 20us (close to the previous value).

There are some scenarios that can occur, such as performing an upgrade of
the virtual I/O server, where the supported max transfer of the backing
device for an ibmvfc HBA can change. If the max transfer of the backing
device decreases, this can cause issues with previously discovered
LUNs. This patch accomplishes two things. First, it changes the default
ibmvfc max transfer value to 1MB. This is generally supported by all
backing devices, which should mitigate this issue out of the box. Secondly,
it adds a module parameter, enabling a user to increase the max transfer
value to values that are larger than 1MB, as long as they have configured
these larger values on the virtual I/O server as well.

A previous change was introduced to prevent data loss during a power-on
reset when a tape is present inside the drive. This commit set the
"pos_unknown" flag to true to avoid operations that could compromise data
by performing actions from an untracked position. The relevant change is
commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling")
As a consequence of this change, a new issue has surfaced: the driver now
returns an "Input/output error" even for empty drives when the drive, host,
or bus is reset. This issue stems from the "flush_buffer" function, which
first checks whether the "pos_unknown" flag is set. If the flag is set, the
user will encounter an "Input/output error" until the tape position is
known again. This behavior differs from the previous implementation, where
empty drives were not affected at system start up time, allowing tape
software to send commands to the driver to retrieve the drive's status and
other information.
The current behavior prioritizes the "pos_unknown" flag over the
"ST_NO_TAPE" status, leading to issues for software that detects drives
during system startup. This software will receive an "Input/output error"
until a tape is loaded and its position is known.
To resolve this, the "ST_NO_TAPE" status should take priority when the
drive is empty, allowing communication with the drive following a power-on
reset. At the same time, the change should continue to protect data by
maintaining the "pos_unknown" flag when the drive contains a tape and its
position is unknown.

The node ptr can point to an already freed ptr, if we hit the path with
an already allocated node. We later dereference that pointer with:
xe_gt_assert(gt, !xe_ggtt_node_allocated(node));
which is a potential UAF. Fix this by not stashing the ptr for node.
Also since it is likely a bad idea to leave config->ggtt_region pointing
to a stale ptr, also set that to NULL by calling
pf_release_vf_config_ggtt() instead of pf_release_ggtt().

Also, in terms of throughput this change has the same effect to
interrupt endpoint as 290ba200815f "Bluetooth: Improve USB driver throughput
by increasing the frame size" had for the bulk endpoint, so users of the
advertisement bearer (e.g. BT Mesh) may benefit from this change.

With the CXL mailbox context split out, cxl_internal_send_cmd() can take
'struct cxl_mailbox' as an input parameter rather than
'struct memdev_dev_state'. Change input parameter for
cxl_internal_send_cmd() and fixup all impacted call sites.

Create a new 'struct cxl_mailbox' and move all mailbox related bits to
it. This allows isolation of all CXL mailbox data in order to export
some of the calls to external kernel callers and avoid exporting of CXL
driver specific bits such has device states. The allocation of
'struct cxl_mailbox' is also split out with cxl_mailbox_init() so the
mailbox can be created independently.

The psc->div[] array has psc->num_div elements. These values come from
when we call clk_hw_register_div(). It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >=
instead of > to prevent an out of bounds read.
