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).

89e8f275be Don't peek at part of a structure via fuword. Does not work well on 
64bit architectures. XXX - have to check other changes in the I4B
distribution, this had been fixed there a long time ago.

acd96e1307 Don't use splimp() to block both net and tty interrupts. Instead, 
block both interrupt levels as appropriate.

6f85104748 Sync with if_sl.c,v 1.67: 
Defer output processing to the software interrupt.

Note, that in the process of doing this, I discovered several
very broken things about this driver, which are not fixed with
this commit.  It should work as well as it previously did, but
this code could be seriously improved.  As soon as I can find
my second Metricom radio, I'll give it a proper shakedown.

Once we have a complete frame, schedule a STRIP software interrupt,

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

d0357bdb4f Slight adjustment to how pfil_head's are registered. Instead of a 
"key" and a "dlt", use a "type" (PFIL_TYPE_{AF,IFNET} for now) and
a val/ptr appropriate for that type.  This allows for more future
flexibility with the pfil_hook mechanism.
