table of functions.
This commit (which is heavily based on work done by Marta Carbone
in this year's GSOC project), removes the goto's and explicit
return from the inner switch(), so we will have a easier time when
putting the blocks into individual functions.

Ideally we should attempt attaching only to known supported devices.
But I am not sure that we have all supported PCI IDs already listed,
and I am too young to die, err, I don't want to take the heat from
causing a trouble to someone.

X-ToDo: drop the default case
Memory accesses are posted in program order by virtue of the
uncacheable memory attribute.
Since GCC, by default, adds acquire and release semantics to
volatile memory loads and stores, we need to use inline assembly
to guarantee it. With inline assembly, we don't need volatile
pointers anymore.
Itanium does not support semaphore instructions to uncacheable
memory.
(gcc 4.x under linux, not sure how real is the complaint).
- rename a macro argument to prevent name clashes.
- add the macro name on a couple of #endif
- add a blank line for readability.

ndis_scan() is called. However, ndis_scan() is invoked from softclock()
and cannot sleep. Move ndis_scan_results() to the ndis' driver's scan_end
hook instead.

using the new option numbers, IP_FW3 and IP_DUMMYNET3.
Right now the modules return an error if called with those arguments
so there is no danger of unwanted behaviour.

No functional differences.
- use the div64() macro to wrap 64 bit divisions
(which almost always are 64 / 32 bits) so they are easier
to handle with compilers or OS that do not have native
support for 64bit divisions;
- use a local variable for p_numbytes even if not strictly
necessary on HEAD, as it reduces diffs with FreeBSD7
- in dummynet_send() check that a tag is present before
dereferencing the pointer.
- add a couple of blank lines for readability near the end of a function

priority for such important information as MASTER/BACKUP state change,
and used a normal logging priority for such innocent messages as receiving
short packet (which is a normal VRRP packet between some other routers) or
receving a CARP packet on non-carp interface (someone else running CARP).
This commit shifts message logging priorities to a more sane default.
so the size and alignment of the ipfw_insn is not compiler dependent.
No changes in the code generated by gcc.
There was only one instance of this kind in our entire source tree,
so i suspect the old definition was a poor choice (which i made).

When the termios CREAD flag is not set, it makes little sense to
allocate an input buffer. Just set the size to 0 in this case to reduce
memory footprint.
Disallow CREAD to be disabled for pseudo-devices to prevent
foot-shooting.
config(8) doesn't parse parantheses and instead treated them as being
part of the device driver name (e.g. '(u3g' vs 'u3g'). While here, fix the
style of these long lines to match the wrapping used for other long lines
in this file.

The hardware is compliant with WDRT specification, so I originally
considered including generic WDRT watchdog support, but decided
against it, because I couldn't find anyone to the code for me.
WDRT seems to be not very popular.
Besides, generic WDRT porbably requires a slightly different driver
approach.

the compression was useless as well. Make sure to not update the data
and return, else we would waste resources when decompressing.
This also avoids the copyback() changing data other consumers like
xform_ipcomp.c would have ignored because of no win and sent out without
noting that compression was used, resulting in invalid packets at the
receiver.

actually send out compressed data or not.
With this, after the opencrypto/deflate changes, IPcomp starts to work
apart from edge cases. Leave it disabled by default until those are
fixed as well.

The <sys/termios.h> header file is hardlinked to <termios.h>. It
contains both the structures and the flag definitions, but also the C
library interface that's implemented by the C library.
This header file has the typical problem of including too many random
things and being badly ordered. Instead of trying to fix this, decompose
it into two header files:
- <sys/_termios.h>, which contains struct termios and the flags.
- <termios.h>, which includes <sys/_termios.h> and contains the C
library interface.
This means userspace has to include <termios.h> for struct termios,
while kernelspace code has to include <sys/tty.h>. Also add a
<sys/termios.h>, which prints a warning message before including
<termios.h>. I am aware that there are some applications that use this
header file as well.
This is needed to avoid running into out of buffer situations
where we cannot alloc a new buffer because we hit the array size
limit (ZBUF).
Use a combined allocation for the struct and the actual data buffer
to not increase the number of malloc calls. [1]
Defer initialization of zbuf until we actually need it.
Make sure the output buffer will be large enough in all cases.
