f4247b5934 Fix a recently introduced panic in if_detach() by delaying
the invalidation of ifindex_table[] entry. Probably this
code should be moved even further down, but for the time being
let's do it this way.

9046571f1c Use if_link instead of the alias if_list, and change a for() into
the TAILQ_FOREACH() form.

Comment the need to store the same info (mac address for ethernet-type
devices) in two different places.

No functional changes. Even the compiler output should be unmodified
by this change.

25a4adcec4 Bring eventhandler callbacks for pf.
This enables pf to track dynamic address changes on interfaces (dailup) with
the "on (<ifname>)"-syntax. This also brings hooks in anticipation of
tracking cloned interfaces, which will be in future versions of pf.

efb4018be7 Improve the SIOCSIFCAP handler a bit:
- allow for ifp->if_ioctl being NULL, as the rest of ifioctl() does;
- give the interface driver a chance to report a error to the caller;
- don't forget to update ifp->if_lastchange upon successful modification
  of interface operation parameters.

36c19a572a Add the kernel side of network interface renaming support.
The basic process is to send a routing socket announcement that the
interface has departed, change if_xname, update the sockaddr_dl
associated with the interface, and announce the arrival of the interface
on the routing socket.

As part of this change, ifunit() is greatly simplified by testing
if_xname directly.  if_clone_destroy() now uses if_dname to look up the
cloner for the interface and if_dunit to identify the unit number.

a8773564ca Cleanup malloc() use in if_attach():
- malloc() returns a void* and does not need a cast
 - when called with M_WAITOK, malloc() can not return NULL so don't
   check for that case.  The result of the check was bogus anyway since
   it would leave the interface broken.

9bf40ede4a 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.

d1dd20be6e Locking for updates to routing table entries. Each rtentry gets a mutex
that covers updates to the contents.  Note this is separate from holding
a reference and/or locking the routing table itself.

Other/related changes:

o rtredirect loses the final parameter by which an rtentry reference
  may be returned; this was never used and added unwarranted complexity
  for locking.
o minor style cleanups to routing code (e.g. ansi-fy function decls)
o remove the logic to bump the refcnt on the parent of cloned routes,
  we assume the parent will remain as long as the clone; doing this avoids
  a circularity in locking during delete
o convert some timeouts to MPSAFE callouts

Notes:

1. rt_mtx in struct rtentry is guarded by #ifdef _KERNEL as user-level
   applications cannot/do-no know about mutex's.  Doing this requires
   that the mutex be the last element in the structure.  A better solution
   is to introduce an externalized version of struct rtentry but this is
   a major task because of the intertwining of rtentry and other data
   structures that are visible to user applications.
2. There are known LOR's that are expected to go away with forthcoming
   work to eliminate many held references.  If not these will be resolved
   prior to release.
3. ATM changes are untested.

ed692400eb I don't know from where the notion that device driver should or
even could call VOP_REVOKE() on vnodes associated with its dev_t's
has originated, but it stops right here.

If there are things people belive destroy_dev() needs to learn how to
do, please tell me about it, preferably with a reproducible test case.

Include <sys/uio.h> in bluetooth code rather than rely on <sys/vnode.h>
to do so.

The fact that some of the USB code needs to include <sys/vnode.h>
still disturbs me greatly, but I do not have time to chase that.

fa882e87a5 Add a new helper function if_printf() modeled on device_printf(). The
function takes a struct ifnet pointer followed by the usual printf
arguments and prints "<interfacename>: " before the results of printf.
Since this is the primary form of printf calls in network device drivers
and accounts for most uses of the ifnet menber if_unit, this
significantly simplifies many printf()s.
