For AHCI attached devices, we report the location and identification
information of the AHCI controller that we're attached to. We also
don't reprot link speed in that case, since we can't get to the PCIe
config space registers to find that out.

When an NVME device is attached via a AHCI controller, we have no access
to its config space. So instead of information about the nvme drive
itself, return info about the AHCI controller as the next best
thing. Since the Intel Hardware RAID support looks at these values, this
likely is best.

Add a quirk to flag AHCI attachment to the controller. This is for any
of the strategies for attaching nvme devices as children of the AHCI
device for Intel's RAID devices. This also has a side effect of cleaning
up resource allocation from failed nvme_attach calls now.

Prior to NVMe 1.3, Intel produced a series of drives that had
performance alignment data in the vendor specific space since no
standard had been defined. Move testing the versions to a quick so the
NVMe NS code doesn't know about PCI device info.

Seems like a copy-paste error, or at least this made more sense when the

Currently the type isn't set in the fbtype struct so any userland
program that call the FBIOGTYPE ioctl will think it's a FBTYPE_SUN1BW
which is far from the truth.
No app that I found find checks the type but at least now it's correct.

Passing up such descriptors to iflib is obviously wasteful.
But the main conern is that we may overrun iri_frags array because of
them. That's been observed in practice.
Also, assert that the number of fragments / descriptors / segments is
less than IFLIB_MAX_RX_SEGS.

This reverts commit 266f97b5e9a7958e365e78288616a459b40d924a, reversing
changes made to a10253cffea84c0c980a36ba6776b00ed96c3e3b.
A mismerge of a merge to catch up to main resulted in files being
committed which should not have been.
Port 9781c28c6d63 and a8837c77efd0 to the mps driver. Before this
change devq was frozen only if some command was sent to the target after
reset started, but release was called always. This change freezes the
devq immediately, leaving mprsas_action_scsiio() check only to cover
race condition due to different lock devq use.
This should also avoid unnecessary requeue of the commands, creating
additional log noise and confusing some broken apps. It also avoids a
'busy' requeue of I/Os failing when we're doing recovery that takes
longer than the normal busy timeout. These I/Os failing can lead to
filesystems being unmounted in the force unmount case for I/O errors.

The vast majority of the busy/unbusy users in the tree don't acquire
Giant before calling device_busy/unbusy. However, if multiple threads
are opening a file, say, that causes the device to busy/unbusy, then we
can race to the root marking things busy. Move to using a reference
count to keep track of how many times a device_t has been made busy. Use
that count to make the same decisions that we'd make with the old device
state.
Note: gpiopps.c uses D_TRACKCLOSE. Others do as well. However, there's a
known race with closes that will be corrected for all the drivers that
do this in a future commit.

we never sleep in the busy/unbusy path, Giant's single threaded semantics
suffice to keep this safe.
