Don't use Maxmem when the amount of memory is meant. Use realmem instead.
Maxmem is not only a MD variable, it represents the highest physical memory
address in use. On systems where memory is sparsely layed-out the highest
memory address and the amount of memory are not interchangeable. Scaling the
AGP aperture based on the actual amount of memory (= realmem) rather than
the available memory (= physmem) makes sure there's consistent behaviour
across architectures.

Tweak the CAM_DATA flags that were added with r251874 to allow source

When a previous call to sbsndptr() leaves sb->sb_sndptroff at the start of an
mbuf that was fully consumed by the previous call, the mbuf ptr returned by the
current call ends up being the previous mbuf in the sb chain to the one that
contains the data we want.

This does not cause any observable issues because the mbuf copy routines happily
walk the mbuf chain to get to the data at the moff offset, which in this case
means they effectively skip over the mbuf returned by sbsndptr().

We can't adjust sb->sb_sndptr during the previous call for this case because the
next mbuf in the chain may not exist yet. We therefore need to detect the
condition and make the adjustment during the current call.

Fix by detecting the special case of moff being at the start of the next mbuf in
the chain and adjust the required accounting variables accordingly.

Take advantage of newly updated f_dialog_{yesno,noyes}() functions from
SVN r251977 (adding an $hline parameter).

When I first wrote the timezone module, it was in sysutils/tzdialog and it
pre-dates bsdconfig. Update the code to take advantage of f_dialog_msgbox().

Change the f_dialog_{yesno,noyes}() function-arguments in `dialog.subr' to
accomodate an $hline value for overriding the default. This change does
not effect any current modules as it turns out that not one single usage of
either f_dialog_yesno() or f_dialog_noyes() relied on accepting more than a
first argument (read: all occurrences quoted the first parameter; so $* was
never depended upon).

This will allow some custom invocations of --yesno and --noyes to roll over
to these functions (for example, in `timezone/timezone').

Add quad port probe support, this gives the admin proper information about the slot

Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX.

Allow the use of 'unsupported' optic modules by a compile option as well.

Add a phy reset capability into the stop code, this is so a static configured
driver will still behave properly when taken down (not being able to unload it).

This revision synchronizes the shared code with Intel internal current code,
and note that it now includes DCB supporting code, this was necessitated by
some internal changes with the code, but it also will provide the opportunity
to develop this feature in the core driver down the road.

I have edited the README to get rid of some of the worse anachronisms in it
as well, its by no means as robust as I might wish at this point however.

Oh, I also have included some conditional stuff in the code so it will be
compatible in both the 9.X and 10 environments.

On some generations of the Intel GPU, disabling of the VGA Display
stops updating the vertical retrace indicator.  The text mouse
renderer in syscons is executing from the callout and spins waiting
for the start of next frame.  As result, after the X server finishes,
since the VGA cannot be turned on, but syscons does not know about
this, the clock swi spins forever.

Hack around the problem by disabling wait for the retrace if KMS is
activated.
