Set UQ_MSC_NO_INQUIRY and UQ_MSC_NO_GETMAXLUN quirks for mass storage,
which is the initial mode of this dongle.
The modem is shipped with at least two firmware versions: 10.X and 11.X,
without ability to update to the newer one.
The 11.X version works more or less fine, but the 10.X one resets after
receiving either an SCSI INQUIRY, or a get_max_lun command.
Since both of those are used for automatic quirk detection, this leads
to a reset cycle making the device somewhat unusable.

Both usb_iface_is_cdrom and usb_msc_auto_quirk functions use SCSI INQUIRY
command to probe various properties of usb mass storage devices.
The problem here is that some very broken devices don't like this command.
Check if UQ_MSC_NO_INQUIRY quirk is set and skip cdrom and quirk
autodetection in that case.

The use of devclass_get_softc() combined with cdev unit numbers is
probably not ideal (probably should be initializing si_drv1 when each
cdev is created instead), but it looks like a bit of a PITA to do, so
just initialize the devclass explicitly instead.

Since vte_reset changes register value to MDCSC_DEFAULT value, which may not
be the original value, thus causing some phy registers read failures.
Restoring VTE_MDCSC value to original after reset solves the link state
flapping issue.

Some AMD EPYC VCPUs generated boot message of the type:
pci4: <unknown> at device 0.0 (no driver attached)
These are displayed for device class 0x13 devices, e.g.:
none8@pci0:130:0:0: class=0x130000 rev=0x00 hdr=0x00 vendor=0x1022 \
device=0x148a subvendor=0x1022 subdevice=0x148a
vendor = 'Advanced Micro Devices, Inc. [AMD]'
device = 'Starship/Matisse PCIe Dummy Function'
class = non-essential instrumentation
Since these devices serve no purpose (no driver attaches) I have
enabled the reporting of suich devices only for verbose boots (a
diversion from the patch provided in the PR).
A verbose boot will now display such devices as:

The other QL_DPRINT*() invocations in qls_init_hw_if() all used the

defines QL_DBG in CFLAGS so doesn't trip over this, but adding qlxge

This entails various changes to make this driver more "modern"
(new-bus vs pre-new-bus) using device_log() and device_printf() rather
than psm%d. It also fixes the device_busy/unbusy calls to use sc->dev
directly rather than looking the device_t up via the devclass and
unit.

Use the drop and enable endpoint context commands to force a reset of
the data toggle for USB 2.0 and USB 3.0 after:
- clear endpoint halt command (when the driver wishes).
- set config command (when the kernel or user-space wants).
- set alternate setting command (only affected endpoints).
Some XHCI HW implementations may not allow the endpoint reset command when
the endpoint context is not in the halted state.

If iommu_gas_match_one has to adjust for a boundary crossing, its
check against maxaddr includes 'offset' in its calculation, to ensure
that the allocated memory does not exceed the max address. However, if
there's no boundary crossing adjustment, then the maxaddr check
disregards 'offset'. Fix that.

cxgbei needs the ability to return different limits based on the
connection (e.g. if the connection is over a T5 adapter or a T6
adapter as well as factoring in the MTU).
This change plumbs through the changes in the ioctls without changing
any of the backends. The limits callback passed to icl_register now
accepts a second socket argument which holds the integer file
descriptor. To support ABI compatiblity for old binaries, the
callback should return "global" values if the socket fd is zero.
The CTL_ISCSI_LIMITS argument used with CTL_ISCSI by ctld(8) now
accepts the socket fd in a field that was previously part of a
reserved spare field. Old binaries zero this request which results in
passing a socket fd of 0 to the limits callback.
The ISCSIDREQUEST ioctl no longer returns limits. Instead, iscsid(8)
invokes a new ISCSIDLIMITS ioctl after establishing the connection via
connect(2). For ABI compat, if the old ISCSIDREQUEST is invoked, the
global limits are still fetched (with a socket fd of 0) and returned.

The result of the request computed in new_status was never returned to
the caller leaving new_status as a set-but-unused variable. Removing
new_status leaves sc->previous_status as a write-only variable.
Removing sc->previous_status leaves current_status as a write-only
variable, so it collapses down to removing the entire
USB_ST_TRANSFERRED case.
Arguably, all of the support for UHID_SNES_STATUS_DT_RD should be
removed as it doesn't return anything to the caller. If the request
should be fixed instead then this commit should be reverted and
new_status should be returned to whoever submitted the request.

When constructing qpair, use the controller's notion of page size rather
than the host's PAGE_SIZE. Currently, these are both 4k, but the arm 16k
page size support requires decoupling.
There's a "hidden" PAGE_SIZE in btoc, so we must change btoc(x) to
howmany(x, ctrlr->page_size) to properly count the number of pages (in
the drive's world view) are needed for various calculations.
With these changes, we the nvme driver operates at production level load
for both host 4k and host 16k page size.
