ifconfig.8: Fix month
kernel/ntfs: Add ntfs_statvfs.

This fixes for example df output for large filesystems.
kernel/ntfs: Remove two unused variables.
mount_ntfs.8: Fix synopsis and add another example (from FreeBSD).
bge: Commit coalesce parameters change in polling code
bge: Improve tiny packets transmission performance on low frequency CPU

Update TX HOST_PROD register a little bit often; mainly to improve
timeliness of packets transmission:
The TX HOST_PROD register is updated after certain amount of TX
descriptors are added to the hardware TX ring.  The default value of the
amount of TX descriptors are 16.  This value could be further tuned by
per-device sysctl node hw.bgeX.tx_wreg.

The default value improves tiny packets transmission performance w/ 5721
on AMD970@800Mhz (770Kpps -> 800Kpps) and it does not increase CPU usage
on AMD970@3500Mhz (CPU usage stays @20%, 5721 could only do 810Kpps).

NOTE: Tuning hw.bgeX.tx_coal_bds to 32 could make packets transmission
performance w/ 5721 on AMD970@800Mhz to be 810Kpps, however, this shows
no performance improvement on commonly used CPU frequency like 2200Mhz
and 3500Mhz.  And this tuning could burden systems not using polling(4).
jme: Improve tiny packets transmission performance on low frequency CPU

Update TXCSR register a little bit often; mainly to improve timeliness of
packets transmission:
The TXCSR register is updated after certain amount of TX descriptors are
added to the hardware TX ring.  The default value of the amount of TX
descriptors are 16.  This value could be further tuned by per-device sysctl
node hw.jmeX.tx_wreg.

The default value improves tiny packets transmission performance w/ JMC250
on AMD970@2200Mhz (831Kpps -> 911Kpps), on AMD970@800Mhz (484Kpps -> 834Kpps)
and it does not increase CPU usage on AMD970@3500Mhz (CPU usage stays @26%,
JMC250 could only do 911Kpps).
cluster - circuit tracking, bug fixes

* Misc virtual circuit tracking work and bug fixes
cluster - Major kernel component work (diskiocom, xdisk, kdmsg)

* Major implementation and stabilization work.  Fix lots of bugs,
  improve the AUTO flags and APIs.

* xdisk and diskiocom are now operational for the first time.

  xdisk is a consumer of remote block devices.  You pass it one end of
  a pipe and use an ioctl to create /dev/xa* devices.  The kernel's
  nominal disk management subsystem handles /dev/serno/* and will also
  probe the /dev/xa* devices to create the slices.

  diskiocom is a block device service.  An ioctl is used to connect a
  raw disk device to the network via a pipe.

* The hammer2 service demon ties the two together over the network.

* Initial testing with a local hammer2 service daemon looping da0 to xa0
  succeeded, ~46MB/sec unoptimized using dd.
kernel - Reorder dsched teardown to fix race

* Remove the struct disk from its list prior to tearing down the device
  instead of after in order to fix a race related to disk enumerations.

* Wait for active references on the disk structure to go away before
  tearing down the device.
cluster - more libdmsg work

* Fix numerous bugs, including a nasty edge case in the encryption code.

* Do a better job locking things (state structures still need help).
cluster - Add 'circ <msgid>' command to cluster debug shell

* Add a debug shell command to help test virtual circuits.
cluster - Kernel cluster code work

* Major stability work.

* Misc bug fixes and cleanups.

* xdisk/diskiocom links are now relatively stable over a real network.
  Still need to deal with reconnects properly.
agp: Sync with FreeBSD

* Add support for AMD64 Family 10h processors. FreeBSD PR: kern/128331
* Add a few VIA bridges for Intel Core/Core 2 and VIA Nano processors
* Fix AGP debugging code
* Rename agp_x86_64.c to agp_amd64.c again, keeping the same file name
  on both DragonFly and FreeBSD
* Fix prototypes to be consistent
* offset parameter has vm_offset_t type
* vm_offset_t is unsigned and therefore can not be negative
* Use si_drv1 instead of dev2unit() inside agp(4).
* i810: Aperture size and stolen memory are now printed on one line
* Add pci ids for Intel Ironlake chipsets
agp: Fix a handful of issues with via agp support

  * Read the pci capability register to identify AGP 3 support
  * Add missing smaller aperture sizes for AGP3 chips.
  * Fix the aperture size calculation on AGP2 chips.
    All sizes between 32M and 256M reported as 256M.
  * Add \n to error string.

This all seems to get the CLE266 EPIA-M board agp working properly
