new 1Gb server controller chip that will be going into production
soon.
BCM5725 combines MAC with triple-speed PHY, a Network Controller
Sideband Interface (NC-SI) and on-chip memory buffer in a single
device. BCM5725 has an Application Processing Engine (APE) that is
capable of on-chip management and offloading features. BCM5725
supports high-precision clock, time stamp registers for
receive/transmit packets and programmable trigger inputs and
watchdog timeouts. These new features are not yet supported by
bge(4).
Many thanks to Broadcom for continuing to support FreeBSD!

These were wrong in the previous commit. They are actually unused

As part of this commit, add an nvme_strvis() function which borrows
heavily from cam_strvis(). This will allow stripping of
leading/trailing whitespace and also handle unprintable characters
in model/serial numbers. This function goes into a new nvme_util.c
file which is used by both the driver and nvmecontrol.

- Add a new address space allocation method (VMFS_OPTIMAL_SPACE) for
vm_map_find() that will try to alter the alignment of a mapping to match
any existing superpage mappings of the object being mapped. If no
suitable address range is found with the necessary alignment,
vm_map_find() will fall back to using the simple first-fit strategy
(VMFS_ANY_SPACE).
- Change mmap() without MAP_FIXED, shmat(), and the GEM mapping ioctl to

beasts still exist unfortunately. More details can be found in other
references, but the short version is that bridges with this bit set ignore
I/O port ranges that alias to valid ISA I/O port ranges. In the driver
this requires not allocating these alias regions from the parent device
(so they are free to be acquired by ISA devices), and ensuring no child
devices use resources from these alias regions.
- Change the pcib_window structure to allow for an array of backing
resources rather than a single resource and update the existing code
to cope with this. Some of the coping requires using the saved
base and limit values in pcib_window instead of using rman operations
on the backing resource.
- Add special handling for allocating and adjusting the I/O port window
of an ISA-enabled bridge to only allocate the non-alias ranges and
add those to the associated resource manager.
- Reject I/O port allocations for a fixed request that conflicts with an
ISA alias range.
- Remove the "no prefected decode" verbose printf during boot. The absence
of a "prefetched decode" line is sufficient.
- Replace the "subtractively decoded bridge" verbose printf with a single
printf that lists all the "special" decoding modes of a bridge: ISA,
subtractive, and VGA.
- Add a custom bus_release_resource() method to the PCI bus driver so that
it can properly free resources for I/O windows of PCI-PCI bridges.
(These resources are not stored in the bridge device's resource list.)

The read DMA request logic operation is based on having sufficient
available space in the transmit data buffer (TXMBUF) before a read
DMA can be requested. There are four read DMA channels that use
the TXMBUF, and the logic checks if the available free space in the
TXMBUF is large enough for all the data in the four Send Buffers
for which buffer descriptors have been fetched. The Enable_Request
signal is asserted only if the free TXMBUF space is larger than the
sum of the four DMA length registers. The power-up default value
of BGE_RDMA_LSO_CRPTEN_CTRL register bit 25 (bit 21 on BCM5720) is
zero, which selects the DMA length registers to connect to the
input of the adder block. The DMA length registers are
asynchronously reset following BCM5719/BCM5720 power-up, and due to
the lack of synchronous deassertion of the length registers reset
signal these resisters may contain uninitialized values following
the reset deassertion.
In the case of the failure the uninitialized DMA length register
values added up to more than the TXMBUF size, which prevented the
assertion of the Enable_Request signal and any subsequent read DMA
to start. This lockup condition is the root cause of failing to
generate any transmit traffic.
To workaround the issue, select alternate output of multiplexers
and transmit the first four Ethernet frames. This overwrites the
DMA length registers with valid values.

o Make sure to clear TxD, TxS, RxD rings in driver initialization.
Otherwise some data in these rings could be interpreted as
'updated' which in turn will advance internally maintained

make the ARM EABI the default ABI on arm, armeb, armv6 and armv6eb.
This is intended to be the default ABI from now on with the old ABI to be
retired. Because of this all users are strongly suggested to upgrade to the
ARM EABI.
As the two ABIs are incompatible it is unlikely upgrading in place will
work. Users should perform a full backup and either use an external machine
to upgrade, or install to an alternative location on their media. They
should also reinstall all ports or packages when these are available.
The only known issues are:
- pkg incorrectly detects the ABI. This is fixed upstream, and will a
patch will be made to the port.
- GDB can have issues with executables built with clang.

Fix multiple kernel panics when VIMAGE is enabled in the kernel.
These fixes are based on patches submitted by Adrian Chadd and Marko Zec.
(1) Set curthread->td_vnet to vnet0 in device_probe_and_attach() just before calling
device_attach(). This fixes multiple VIMAGE related kernel panics
when trying to attach Bluetooth or USB Ethernet devices because
curthread->td_vnet is NULL.
(2) Set curthread->td_vnet in if_detach(). This fixes kernel panics when detaching networking
interfaces, especially USB Ethernet devices.
(3) Use VNET_DOMAIN_SET() in ng_btsocket.c
(4) In ng_unref_node() set curthread->td_vnet. This fixes kernel panics
when detaching Netgraph nodes.
Bring in the changes from the FUSE kernel interface 7.10
(available under a BSD license).
After 7.10 the linux FUSE developers added support for a
controversial CUSE driver and some linux especific
features that are unlikely to find its way into FreeBSD.
We currently don't implement any of the new features so we
are *not* bumping the FUSE_KERNEL_MINOR_VERSION. The header
should, nevertheless, serve as a template to add the new
features in a compatible manner.
While here adopt some minor cleanups from the upstream version
like removing FUSE_MAJOR and FUSE_MINOR which were never
used. Also add multiple inclusion header guards,
We need to fix wpa_supplicant because it checks whether the card has
ic_cryptocaps set. Since net80211 can do software encryption this check in
