martin 83930a016c Demangle an #ifdef mess and make all ioctl routines take an u_long
as the command argument. Before we were subject to subtle sign extension
differences depending on char being signed or unsigned.

martin 3caa4d3f4c Specify the size of the framing added to packets (in this case: zero), so
if_sppsubr.c can calculate correct statistics.

martin 5171d409a5 First step to cleanup the hardware driver <-> upper layers interface.
This now provides slightly more functionality than the FreeBSD layer1-newbus
interface. It was meant to be a simple change to one header and a few
c files, but the change rippled all through various stuff.

To prevent a change to the kernel<->userland interface right now the kernel
is now lying about card types to userland (but who cares). This will be fixed
when the userland interface changes, after layer 3 <-> layer 4 has been
fixed.

Functional changes:

Provide a clean interface for hardware drivers to attach to the upper
layers. This will need another small change in the B-channel handling
when a similar change to the layer 3 <-> layer 4 interface happens.

Avoid passing indices into global arrays of pointers around, instead pass
the pointers itself. Don't code hardware driver types by predefined magic
numbers (think LKM). Prepare for detachable drivers (think pcmcia).

While there remove some sets of function pointers always pointing to the
same function (meant to be the configurable set of D channel protocol
handlers). It is unlikely another supported D-channel protocol will fit into
that (maximal layer interface) abstraction. When we get support for another
protocol, we will need to come up with a workable interface. Besides, the
old implementation was, uhm, strange.

martin 4ea2a81ad5 Fix my incomplete attempt to ALTQify this so it now actually works.
Thanks to Ignatios for pointing out the problem and to Jason for spotting
the main error.

thorpej fc5dafc79b Fix a rather annoying problem where the sockaddr_dl which holds
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.

Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach().  Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).

Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach().  Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.

While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).

martin 6b82e7fe42 64bit police.
Rumors say there are archs without ISA busses, so avoid including
(uneccesarily) isa bus headers in MI files.
XXX this is the minimal solution, layer interface calls will have
XXX to be revisited later
