Add kqueue support to if_tun. Loosely based on if_tap changes.
Two almost identical patches based on the if_tap work were submitted
via GNATS; I started out with the patch in 100796 from David Gilbert,
but could have easily started with the patch from Vilmos Nebehaj which
I found only later.

Optionally pad outgoing frames to the minimum of 60 bytes (excl. FCS)
before tagging them. This can help to work around brain-damage in some
switches that fail to pad a frame after untagging it if its length drops
below the minimum. This option is blessed by IEEE Std 802.1Q (2003 Ed.),
paragraph C.4.4.3.b. It's controlled by sysctl net.link.vlan.soft_pad.

'show thread' (currently doesn't work due to a ddb bug that in 6.x
that causes 'show thread' to be treated as 'show threads'), 'show lockmgr',
'show sleepchain', 'show lockchain', 'show allchains', 'show locktree',
'show sleepq', and 'show turnstile'.

Don't reset Tx threshold value whenever xl_init_locked() is called.
Instead the threshould is initialized in device attach. Later the
threshold could be increased in Tx underrun error and the new
threshold should be used in xl_init_locked().
Due to the poor PHY documentation from RealTek I can't sure but I
think the RealTek PHY needs driver to set RGEPHY_BMCR_AUTOEN bit of
RGEPHY_MII_BMCR register and proper ANAR register setting for manual
media type selection.
This fixes long standing manual media type selection bug in rgephy(4).
Fix invalid reference of mbuf chains.
Use proper pointer dereference to inform modified mbuf chains to
caller.
While I'm here perform checksum offload setup after loading DMA
maps as m_defrag(9) can return new mbuf chains.
- In addition to -b (suppress builds) add -k (suppress kernel build) and
-w (suppress world).
- Create the diskless magic files in /etc during the install_etc()
step instead of setup_nanobsd().
- When creating the NanoBSD disk image, install boot blocks from the
newly-built world, in preference to those from the host system.
- 'make distribution' must be run from src, not src/etc.
Track interface department events and detach vlans from
departing trunk so that we don't get into trouble later
by dereferencing a stale pointer to dead trunk's things.
Use NET_LOCK_GIANT() and VFS_LOCK_GIANT() instead of unconditionally
acquiring Giant in kern_sendfile().
Guard against the forced reclamation of a vnode in kern_sendfile().
Ensure that vm_object_deallocate() doesn't dereference a stale object
pointer: When vm_object_deallocate() sleeps because of a non-zero
paging in progress count on either object or object's shadow,
vm_object_deallocate() must ensure that object is still the shadow's
backing object when it reawakens. In fact, object may have been
deallocated while vm_object_deallocate() slept. If so, reacquiring
the lock on object can lead to a deadlock.
Guess the number of arguments to a function somewhat better.
Now GCC likes to stick a "mov %eax, %FOO" instruction before
"addl $BAR, %esp" if the function just called returns an int,
which is a very common case in the kernel.
Return -1 from db_numargs() if number of args couldn't be guessed.
Use this later to indicate in backtrace output that args shown are
uncertain.
Always supply curthread as argument to nfs_asyncio and nfs_doio
in nfs_strategy. Otherwise, for some buffers, signals would be ignored
at the intr mounts.

- Improve and extend mark-up.
- Don't use full path in .Nm (we just don't do that).
- Correct some frivolous and poorly rendering language,
such as using possessive case for .Nm or .Fl .
- Use the same capitalization for "user ID" as in setuid(2) and getuid(2).
- Bring SEE ALSO in accord with the text.
