* That lock isn't actually held during reset - just the whole TX/RX path
  is paused.  So, remove the assertion.

* Log the TX queue status - how many hardware frames are active in the
  MAC and whether the queue is active.

6f2af3fcf3 Rework the handling of the tmpfs node backing swap object and tmpfs
vnode v_object to avoid double-buffering.  Use the same object both as
the backing store for tmpfs node and as the v_object.

Besides reducing memory use up to 2x times for situation of mapping
files from tmpfs, it also makes tmpfs read and write operations copy
twice bytes less.

VM subsystem was already slightly adapted to tolerate OBJT_SWAP object
as v_object. Now the vm_object_deallocate() is modified to not
reinstantiate OBJ_ONEMAPPING flag and help the VFS to correctly handle
VV_TEXT flag on the last dereference of the tmpfs backing object.

e5f299ff76 Make vm_object_page_clean() and vm_mmap_vnode() tolerate the vnode'
v_object of non OBJT_VNODE type.

For vm_object_page_clean(), simply do not assert that object type must
be OBJT_VNODE, and add a comment explaining how the check for
OBJ_MIGHTBEDIRTY prevents the rest of function from operating on such
objects.

For vm_mmap_vnode(), if the object type is not OBJT_VNODE, require it
to be for swap pager (or default), handle the bypass filesystems, and
correctly acquire the object reference in this case.

9b8851faae Assert that the object type for the vnode' non-NULL v_object, passed
to vnode_pager_setsize(), is either OBJT_VNODE, or, if vnode was
already reclaimed, OBJT_DEAD.  Note that the later is only possible
due to some filesystems, in particular, nfsiods from nfs clients, call
vnode_pager_setsize() with unlocked vnode.

More, if the object is terminated, do not perform the resizing
operation.

3d31767952 Eliminate the layering violation in the kern_sendfile(). When quering
the file size, use VOP_GETATTR() instead of accessing vnode vm_object
un_pager.vnp.vnp_size.

Take the shared vnode lock earlier to cover the added VOP_GETATTR()
call and, as consequence, the whole internal sendfile loop.  Reduce vm
object lock scope to not protect the local calculations.

Note that this is the last misuse of the vnp_size in the tree, the
others were removed from the ELF image activator by r230246.

e8e4cdbacb Let's align correctly by setting to 17.
OpenCISS states that if the value is 0, then the driver should try a value
of 31.  That's just silly.  Set to 17 so that the subtraction for maxio

bdde570562 Change maxio to reflect variable hardware configurations.
If max_sg_length is 0, then we default to 16

If max_sg_length is less than CISS_MAX_SG_ELEMENTS, then
we will set round the value of max_sg_length to the nearest
power of 2 and use it to align maxio.

Else, we will use CISS_MAX_SG_ELEMENTS for our calculations.

9fe9ba5bef Teach GEOM and CAM about the difference between the max "size" of r/w and delete
requests.

sys/geom/geom_disk.h:
        - Added d_delmaxsize which represents the maximum size of individual
          device delete requests in bytes. This can be used by devices to
          inform geom of their size limitations regarding delete operations
          which are generally different from the read / write limits as data
          is not usually transferred from the host to physical device.

sys/geom/geom_disk.c:
        - Use new d_delmaxsize to calculate the size of chunks passed through to
          the underlying strategy during deletes instead of using read / write
          optimised values. This defaults to d_maxsize if unset (0).

        - Moved d_maxsize default up so it can be used to default d_delmaxsize

sys/cam/ata/ata_da.c:
        - Added d_delmaxsize calculations for TRIM and CFA

sys/cam/scsi/scsi_da.c:
        - Added re-calculation of d_delmaxsize whenever delete_method is set.

        - Added kern.cam.da.X.delete_max sysctl which allows the max size for
          delete requests to be limited. This is useful in preventing timeouts
          on devices who's delete methods are slow. It should be noted that
          this limit is reset then the device delete method is changed and
          that it can only be lowered not increased from the device max.

da98dc7f43 Added available delete methods discovery during device probe, including the
maximum sizes for said methods, which are used when processing BIO_DELETE
requests. This includes updating UNMAP support discovery to be based on
SBC-3 T10/1799-D Revision 31 specification.

Added ATA TRIM support to cam scsi devices via ATA Pass-Through(16)

sys/cam/scsi/scsi_da.c:
        - Added ATA Data Set Management TRIM support via ATA Pass-Through(16)
          as a delete_method

        - Added four new probe states used to identity available methods and their
          limits for the processing of BIO_DELETE commands via both UNMAP and the
          new ATA TRIM commands.

        - Renamed Probe states to better indicate their use

        - Added delete method descriptions used when informing user of issues.

        - Added automatic calculation of the optimum delete mode based on which
          method presents the largest maximum request size as this is most likely
          to result in the best performance.

        - Added WRITE SAME max block limits

        - Updated UNMAP range generation to mirror that used by ATA TRIM, this
          optimises the generation of ranges and fixes a potential overflow
          issue in the count when combining multiple BIO_DELETE requests

        - Added output of warnings about short deletes. This should only ever
          be triggered on devices that fail to correctly advertise their supported
          delete modes / max sizes.

        - Fixed WS16 requests being incorrectly limited to 65535 in length.

6f926c0b82 Added a sysctl (kern.geom.dev.delete_max_sectors) to control the maximum
size of a delete request sent to the providing device performed by g_dev_ioctl.

This allows the kernel and apps via ioctl e.g. newfs -E to request large LBA
deletes which siginificantly improves performance.

Previously this was hard coded to 65536 sectors, the new default is 262144
which doubles the throughput of deletes on commonly available SSD's.

In tests on a Intel 520 120GB FW: 400i disk it improved the delete throughput
from 1.6GB/s to over 2.6GB/s on a full disk delete such as that done via
newfs -E

For some SSD's where delete time is pretty much constant, no matter what
the request, setting this to 0 will provide significantly better throughput
e.g. Samsung 840 240GB FW DXT07B0Q @ 262144 = 79G/s, @ 0 = 2259G/s
