Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

on. MCOUNT and FAKE_MCOUNT() may clobber all the call-used registers,
and one FAKE_MCOUNT() was placed so that an active %eax was clobbered.
The fix is to move this FAKE_MCOUNT() earlier where it should have
been anyway.
Fixed 3 layers of bitrot in the comment about why this FAKE_MCOUNT()
was where it was by removing the comment. (mcount() should be called
as early as possible after entering a new level, but an implementation
detail got in the way until 3 layers of changes ago.)
Kernel profiling still gives wrong results because the new interrupt
code rearranged object files too much. mcount() depends on trap,
syscall and interrupt handlers being between certain magic labels with
interrupt handlers last, and on nothing else being there. Splitting
up exception.o moved the magic labels to effectively random places
relative to what they are supposed to delimit. This mainly broke the
call graph; the flat profile is still usable.
code. Both the driver and the new code were wrong. Driver interrupt
handlers are supposed to take "void *vsc" arg, but some including all
COMPAT_ISA drivers and the pci part of the cy driver want an "int unit"
arg. They got this using bogus casts of function pointers which should
have kept working despite their bogusness. However, the new interrupt
code doesn't honor requests to pass an arg of ((void *)0), so things
are very broken if the arg is actually a representation of unit 0.
The fix is to use a normal "void *vsc" arg for the pci case and a
wrapper for the COMPAT_ISA case (of the cy driver). This cleans up
new-busification of the pci case but takes the COMPAT_ISA case a little
further from new-bus. The corresponding bug for the COMPAT_ISA case
has already been fixed similarly using a wrapper in compat_isa.c and
we need another wrapper just to undo that.
Fixed some directly related style bugs (mainly by removing compatibility
cruft).
cy.c:
Fixed an indirectly related old bug in cyattach_common(). A wrong status
was returned in the unlikely event that malloc() failed.

issues which they found and asked to be changed so 3ware can offcially
support the driver.
Summary of the most significant changes:
- TWE_OVERRIDE is no longer supported
- If twe_getparam failed, bogus data would be returned to the caller
- Cache the device unit in the twe_drive structure to aid debugging
- Add the 3ware driver version.
- Proper return error codes for many functions.
- Track the minimum queue length statistics
- 4.x compat: use the cached unit number from the twe_drive structure
instead of the the cached si_drv2. 3ware found that after many loads
and unloads that si_drv2 became corrupted. This did not happen in
-current.

o Back out workaround for not resetting lucent cards more than once. With
these fixes, it appaers they are no longer necessary.
o Set wi_gone when the card goes awol: typically when we get 0xffff back from
the card. Also, don't interact with a card that's gone, so we fail in
seconds rather than minutes. Also reduce amount of time we wait to .5s
in wi_cmd.
o clear wi_gone on ifconfig down to give some cards a chance after they wedge
(this appears to unwedge one of my prism cards with old firmware). ifconfig
up will fail quickly enough if the card really is out to lunch.
o Add delay in wi_init of 100ms.
o wi_stop(ifp, 0->1) changes so that we clear sc_enabled so that we
exit out of the interrupt routine by just acking the interrupt

code is compiled in to support the O_IPSEC operator. Previously no
support was included and ipsec rules were always matching. Note that
we do not return an error when an ipsec rule is added and the kernel
does not have IPsec support compiled in; this is done intentionally
but we may want to revisit this (document this in the man page).

forced unmount case. Otherwise, a file system that is referenced
only by process fd_cdir/fd_rdir references to the file system root
vnode will be successfully unmounted without the MNT_FORCE flag.
The previous behaviour was not compatible with the unmount semantics
required by amd(8), so file systems could be unexpectedly unmounted
while there were still references to the file system root directory.

permitting the administrator to select a securelevel top operate
at. Include a helpfile summarizing some of the information from
init(8). This allows for explicit configuration of securelevels,
which was previously implicit in Security Profile selection.
Currently, there are no checkboxes for the active securelevel,
because sysinstall's facilities for deriving "current settings"
from rc.conf may use only one variable, not two, and I opted for
the simplest approach at this point.
