in the clocks=<...> properties of their FDT data. The clock properties
consist of 2-cell tuples, each containing a clock device node reference and
a clock number. A clock device driver can register itself as providing
this interface, then other drivers can turn the FDT clock node reference
into the corresponding device_t so that they can use the interface to query
and manipulate their clocks.
This provides convenience functions to enable or disable all the clocks
listed in the properties for a device, so most drivers will be able to
manage their clocks with a single call to fdt_clock_enable_all(dev).
- It was decided to change the driver name to if_ixl for FreeBSD
- This release adds the VF Driver to the tree, it can be built into
the kernel or as the if_ixlv module
- The VF driver is independent for the first time, this will be
desireable when full SRIOV capability is added to the OS.
- Thanks to my new coworker Eric Joyner for his superb work in
both the core and vf driver code.
Enjoy everyone!

Mostly bugfixes or features developed in the past 6 months,
so this is a 10.1 candidate.
Basically no user API changes (some bugfixes in sys/net/netmap_user.h).
In detail:
1. netmap support for virtio-net, including in netmap mode.
Under bhyve and with a netmap backend [2] we reach over 1Mpps
with standard APIs (e.g. libpcap), and 5-8 Mpps in netmap mode.
2. (kernel) add support for multiple memory allocators, so we can
better partition physical and virtual interfaces giving access
to separate users. The most visible effect is one additional
argument to the various kernel functions to compute buffer
addresses. All netmap-supported drivers are affected, but changes
are mechanical and trivial
3. (kernel) simplify the prototype for *txsync() and *rxsync()
driver methods. All netmap drivers affected, changes mostly mechanical.
4. add support for netmap-monitor ports. Think of it as a mirroring
port on a physical switch: a netmap monitor port replicates traffic
present on the main port. Restrictions apply. Drive carefully.
5. if_lem.c: support for various paravirtualization features,
experimental and disabled by default.
Most of these are described in our ANCS'13 paper [1].
Paravirtualized support in netmap mode is new, and beats the
numbers in the paper by a large factor (under qemu-kvm,
we measured gues-host throughput up to 10-12 Mpps).
A lot of refactoring and additional documentation in the files
in sys/dev/netmap, but apart from #2 and #3 above, almost nothing
of this stuff is visible to other kernel parts.
Example programs in tools/tools/netmap have been updated with bugfixes
and to support more of the existing features.
This is meant to go into 10.1 so we plan an MFC before the Aug.22 deadline.
A lot of this code has been contributed by my colleagues at UNIPI,
including Giuseppe Lettieri, Vincenzo Maffione, Stefano Garzarella.

options into kern.opts.mk and change all the places where we use
src.opts.mk to pull in the options. Conditionally define SYSDIR and
use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all
instances of CURDIR/../../etc with STSDIR, but only in the affected
files.
As a special compatibility hack, include bsd.owm.mk at the top of
kern.opts.mk to allow the bare build of sys/modules to work on older
systems. If the defaults ever change between 9.x, 10.x and current for
these options, however, you'll wind up with the host OS' defaults
rather than the -current defaults. This hack will be removed when
we no longer need to support this build scenario.

device attachment on arm platforms. If this is defined, nexus attaches
early in BUS_PASS_BUS, and other busses and devices attach later, in the
pass number they are set up for. Without it defined, nexus attaches in
BUS_PASS_DEFAULT and thus so does everything else, which is status quo.
Arm platforms which use FDT data to enumerate devices have been relying
on devices being attached in the exact order they're listed in the dts
source file. That's one of things currently preventing us from using
vendor-supplied fdt data (because then we don't control the order of the
devices in the data). Multi-pass attachment can go a long way towards
solving that problem by ensuring things like clock and interrupt drivers
are attached before the more mundane devices that need them.
The long-term goal is to have all arm fdt-based platforms using multipass.
This option is a bridge to that, letting us enable it selectively as
platforms are converted and tested (the alternative being to just throw
a big switch and try to fight fires as they're reported).
handled by creator(4) (Sun Creator 3D, Elite 3D, etc.). This provides
vt(4) consoles on all devices currently supported by syscons on sparc64.
The driver should also be easily adaptable to support newer Sun framebuffers
such as the XVR-500 and higher.
Many thanks to dumbbell@ (Jean-Sebastien Pedron) for testing this remotely
during development.
The MD allocators were very common, however there were some minor
differencies. These differencies were all consolidated in the MI allocator,
under ifdefs. The defines from machine/vmparam.h turn on features required
for a particular machine. For details look in the comment in sys/sf_buf.h.
As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have
machine/sf_buf.h, which is usually quite small.

so it really should not be under "optional inet". The fact that uipc_accf.c
lives under kern/ lends some weight to making it a "standard" file.
Moving kern/uipc_accf.c from "optional inet" to "standard" eliminates the
need for #ifdef INET in kern/uipc_socket.c.
Also, this meant the net.inet.accf.unloadable sysctl needed to move, as
net.inet does not exist without networking compiled in (as it lives in
netinet/in_proto.c.) The new sysctl has been named net.accf.unloadable.
In order to support existing accept filter sysctls, the net.inet.accf node
has been added netinet/in_proto.c.

This allows to clone VMs and move them between LUNs inside one storage
host without generating extra network traffic to the initiator and back,
and without being limited by network bandwidth.
LUNs participating in copy operation should have UNIQUE NAA or EUI IDs set.
For LUNs without these IDs VMWare will use traditional copy operations.
Beware: the above LUN IDs explicitly set to values non-unique from the VM
cluster point of view may cause data corruption if wrong LUN is addressed!

implement options TERMINAL_{KERN,NORM}_ATTR. These are aliased to

Note on the naming: Although affecting the output of vt(4), technically
kern/subr_terminal.c is primarily concerned with changing default colors
so it would be inconsistent to term these options VT_{KERN,NORM}_ATTR.

In addition to stopping breaking the layering violation, it also

One consequence of the change is that ffs_rawread.o is always linked
