During normal use the cmdfifo will never wrap internally and cmdfifo_cdb_offset
will always indicate the start of the SCSI CDB. However it is possible that a
malicious guest could issue an invalid ESP command sequence such that cmdfifo
wraps internally and cmdfifo_cdb_offset could point beyond the end of the FIFO
data buffer.
Add an extra check to fifo8_peek_buf() to ensure that if the cmdfifo has wrapped
internally then esp_cdb_ready() will exit rather than allow scsi_cdb_length() to
access data outside the cmdfifo data buffer.

The esp_cdb_length() function is only used as part of a calculation to determine
whether the cmdfifo contains an entire SCSI CDB. Rework esp_cdb_length() into a
new esp_cdb_ready() function which both enables us to handle the case where
scsi_cdb_length() returns -1, plus simplify the logic for its callers.

If the group of the highest priority pending interrupt is disabled
via ICC_IGRPEN*, the ICC_HPPIR* registers should return
INTID_SPURIOUS, not the interrupt ID. (See the GIC architecture
specification pseudocode functions ICC_HPPIR1_EL1[] and
HighestPriorityPendingInterrupt().)
Make HPPIR reads honour the group disable, the way we already do
when determining whether to preempt in icc_hppi_can_preempt().

This fixes the invalid bInterfaceProtocol value 0x04 in the USB audio
AudioControl descriptors. It should be zero. While Linux and Windows
forgive this error, macOS 14 Sonoma does not. The usb-audio device does
not appear in macOS sound settings even though the device is recognized
and shows up in USB system information. According to the USB audio class
specs 1.0-4.0, valid values are 0x00, 0x20, 0x30 and 0x40. (Note also
that Linux prints the warning "unknown interface protocol 0x4, assuming
v1", but then proceeds as if the value was zero.)
This also fixes the invalid wTotalLength value in the multi-channel
setup AudioControl interface header descriptor (used when multi=on
and out.mixing-engine off). The combined length of all the descriptors
there add up to 0x37, not 0x38. In Linux, "lsusb -D ..." displays
incomplete descriptor information when this length is incorrect.

It is incorrect to have the VIRTIO_NET_HDR_F_NEEDS_CSUM set when
checksum offloading is disabled so clear the bit.
TCP/UDP checksum is usually offloaded when the peer requires virtio
headers because they can instruct the peer to compute checksum. However,
igb disables TX checksum offloading when a VF is enabled whether the
peer requires virtio headers because a transmitted packet can be routed
to it and it expects the packet has a proper checksum. Therefore, it
is necessary to have a correct virtio header even when checksum
offloading is disabled.
A real TCP/UDP checksum will be computed and saved in the buffer when
checksum offloading is disabled. The virtio specification requires to
set the packet checksum stored in the buffer to the TCP/UDP pseudo
header when the VIRTIO_NET_HDR_F_NEEDS_CSUM bit is set so the bit must
be cleared in that case.

The io_timeout property, introduced in c9b6609 (part of 6.0) is
silently overwritten by the hardcoded default value of 30 seconds
(DEFAULT_IO_TIMEOUT) in scsi_generic_realize because that function is
being called after the properties have already been applied.
The property definition already has a default value which is applied
correctly when no value is explicitly set, so we can just remove the
code which overrides the io_timeout completely.
This has been tested by stracing SG_IO operations with the io_timeout
property set and unset and now sets the timeout field in the ioctl
request to the proper value.

VDUSE requires that virtqueues are first enabled before the DRIVER_OK
status flag is set; with the current API of the kernel module, it is
impossible to enable the opposite order in our block export code because
userspace is not notified when a virtqueue is enabled.
This requirement also mathces the normal initialisation order as done by
the generic vhost code in QEMU. However, commit 6c482547 accidentally
changed the order for vdpa-dev and broke access to VDUSE devices with
this.
This changes vdpa-dev to use the normal order again and use the standard
vhost callback .vhost_set_vring_enable for this. VDUSE devices can be
used with vdpa-dev again after this fix.
vhost_net intentionally avoided enabling the vrings for vdpa and does
this manually later while it does enable them for other vhost backends.
Reflect this in the vhost_net code and return early for vdpa, so that
the behaviour doesn't change for this device.
