support with ath(4) and VIMAGE.
Right now the VIMAGE code doesn't supply a default vnet context during:
* hotplug attach;
* any device detach.
It special cases kldload/boot time probing (by setting the context to
vnet0) but that doesn't occur when probing devices during a bus rescan -
eg, adding a cardbus card.
These will eventually go away when the VIMAGE support extends to providing
default contexts to hotplug attach/detach.
audio devices. This endpoint gives clues to the USB host about the
actual data rate on asynchronous endpoints and makes the more
expensive USB audio devices usable under FreeBSD.
The Linux USB audio driver was used as reference for the
automagic shift of the received value.

fragment rate lookups correctly, add a comment describing exactly that.
The assumption in the fragment duration code is the duration of the next
fragment will match the rate used by the current fragment. But I think
a rate lookup is being done for _each_ fragment. For older pre-sample
rate control this would almost always be the case, but for sample
it may be incorrect more often then correct.

Also update the port reset time from 250ms to 50ms. Some USB devices
have a hard limit in hardware at 222ms for the port reset time and will
not enumerate unless this delay is closer to the usb.org defined value.
This patch can fix enumeration with some USB devices.

Fix the issue by setting BGE_PHY_NO_WIRESPEED such that brgphy(4)

In particular, do not lock Giant conditionally when calling into the
filesystem module, remove the VFS_LOCK_GIANT() and related
macros. Stop handling buffers belonging to non-mpsafe filesystems.
The VFS_VERSION is bumped to indicate the interface change which does
not result in the interface signatures changes.

parent adapter's _DOD list, only check the low 16 bits of both _ADR and
_DOD. The language in the ACPI spec seems to indicate that the _ADR values
should exactly match the entries in _DOD. However, I assume that the
masking added to _DOD values was added to work around some known busted
machines (the commit history doesn't indicate either way), and the ACPI
spec does require that the low 16 bits are unique for all video outputs,
so only check the low 16 bits should be fine.
This fixes recognition of video outputs that use the new standardized
device ID scheme in ACPI 3.0 that set bit 31 such as certain Dell laptops.

that revises the netmap memory allocator so that the
various parameters (number and size of buffers, rings, descriptors)
can be modified at runtime through sysctl variables.
The changes become effective when no netmap clients are active.
The API is mostly unchanged, although the NIOCUNREGIF ioctl now
does not bring the interface back to normal mode: and you
need to close the file descriptor for that.
This change was necessary to track who is using the mapped region,
and since it is a simplification of the API there was no
incentive in trying to preserve NIOCUNREGIF.
We will remove the ioctl from the kernel next time we need
a real API change (and version bump).
Among other things, buffer allocation when opening devices is
now much faster: it used to take O(N^2) time, now it is linear.

doesn't automatically clear when VDD rises above Vlow again and needs to be
cleared manually. However, apparently this needs all of the time registers
to be set, i.e. pcf8563_settime(), and not just PCF8563_R_SECOND in order
for PCF8563_R_SECOND_VL to stick. Thus, we just issue a warning during
pcf8563_attach() rather than failing with ENXIO in case it is set.

This eliminates the need to manage queue depth at the nvd(4) level for
Chatham prototype board workarounds, and also adds the ability to
accept a number of requests on a single qpair that is much larger
than the number of trackers allocated.
