The aim of this function is to eventually be the completion entry point
for all 802.11 encapsulated mbufs. All the wifi drivers end up doing
what is in this function so it's an easy win to turn it into a net80211
method and abstract out this code.
Ideally the drivers will all eventually be modified to queue up completed
mbufs and call this function with all the driver locks not held.
This will allow for some much more interesting software queue handling
in the future (like net80211 based A-MSDU, fast-frames, A-MPDU aggregation
and retransmission.)

Newer FreeBSD installs require an install(1) that supports the new flags.
This adds ${MAKEOBJDIRPREFIX}${.CURDIR}/tmp/legacy/{bin,usr/{bin,sbin}}
to the PATH while generating an mtree database for 'make release'.
Note that the problem only exists here because mm-mtree.sh generates
its own object tree to avoid mucking with the existing one, which
results in a PATH containing legacy utility dirs that are empty.
- Use queue size fields from the Tx/Rx queues in various places
instead of (currently the same values) from the softc.
- Fix potential crash in detach if the attached failed to alloc
queue memory.
- Move the VMXNET3_MAX_RX_SEGS define to a better spot.
- Tweak frame size calculation w.r.t. ETHER_ALIGN. This could be
tweaked some more, or removed since it probably doesn't matter
much for x86 (and the x86 class of machines this driver will
be used on).
These programs and everything using libzpool rely on the embedded asserts to
verify the correctness of operations. Given that, the core dumps would be
useless without debug symbols.
- Route PCI interrupt for NIC
- Make "no mapping" warning more user-friendly: add device name and mention
that it's IRQ mapping
- Do not overlap ICUs' IO window with PCI devices' IO windows by starting
IO rman at offset 0x100
for the available pbuf when passed vnode is backing md(4). Other i/o
directed to the same md device might already hold pbufs, and then we
could deadlock since only our progress can free a pbuf needed for
wakeup.

of alternate display layout (introduced in r254237); however, for all other
layouts (incl. default), the release name is displayed at lower-right.

Promoting base pages to superpages can increase TLB coverage and allow for
efficient use of page table entries. This development provides FreeBSD/ARM
with superpages management mechanism roughly equivalent to what we have for
i386 and amd64 architectures.
1. Add mechanism for automatic promotion of 4KB page mappings to 1MB section
mappings (and demotion when not needed, respectively).
2. Managed and non-kernel mappings are now superpages-aware.
3. The functionality can be enabled by setting "vm.pmap.sp_enabled" tunable to
a non-zero value (either in loader.conf or by modifying "sp_enabled"
variable in pmap-v6.c file). By default, automatic promotion is currently
disabled.

The FFLAGS and OFLAGS now work correctly also for files opened with O_EXEC.
Except possibly fuse, the other users pass values without O_EXEC set. fuse
appears to assume O_EXEC is handled correctly.
Although F_SETFL may not be commonly used for execute-only file descriptors,
F_GETFL may be useful to find the access mode.
This driver is based on Linux 3.8 and a previous effort by kan@.
More informations about this project can be found on the FreeBSD wiki:
https://wiki.freebsd.org/AMD_GPU
The driver is split into:
sys/dev/drm2:
The driver sources.
sys/modules/drm2/radeonkmw:
The driver main kernel module's Makefile.
sys/modules/drm2/radeonkmsfw:
All firmware kernel module Makefiles. There's one directory and one
Makefile for each firmware.
sys/contrib/dev/drm2/radeonkmsfw:
All firmware binary sources.
tools/tools/drm/radeon
Tools to update firmwares or regenerate some headers.
Merging the driver to FreeBSD 9.x may be possible but not a priority for
now.

Here are two new functions to map and unmap the Video BIOS:
void * vga_pci_map_bios(device_t dev, size_t *size);
void vga_pci_unmap_bios(device_t dev, void *bios);
The BIOS is either taken from the shadow copy made by the System BIOS at
boot time if the given device was used for the default display (i386,
amd64 and ia64 only), or from the PCI expansion ROM.
Additionally, one can determine if a given device was the default
display at boot time using the following new function:
void vga_pci_unmap_bios(device_t dev, void *bios);
