acd3428b7d Sweep kernel replacing suser(9) calls with priv(9) calls, assigning
specific privilege names to a broad range of privileges.  These may
require some future tweaking.

3dde86fe4c Backout if_cp 1.26, if_ct 1.27, if_cx 1.47 by obrien:
----------------------------
	revision 1.26
	date: 2005/09/07 09:53:35;  author: obrien;  state: Exp;  lines: +1452 -1453
	Reorder code to not depend on an ISO-C illegal forward extern declaration.
	----------------------------

Reason: do not move large functions location without serious reason. The same
could be done by forward function declaration. Please do not enlarge diff
without a reason any more.

Backout if_cp 1.27
----------------------------
	revision 1.27
	date: 2005/09/19 03:10:16;  author: imp;  state: Exp;  lines: +3 -2
	Make sure that we call if_free(ifp) after bus_teardown_intr.  Since we
	could get an interrupt after we free the ifp, and the interrupt
	handler depended on the ifp being still alive, this could, in theory,
	cause a crash.  Eliminate this possibility by moving the if_free to
	after the bus_teardown_intr() call.

Reason: bad previous commit. Would be restored by next commit.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

You could turn this off by debug.mpsafenet=0 for full network

be4252b367 Slight cosmetic changes.
Also introduce a macro to be called by persistent nodes to signal their
persistence during shutdown to hide this mechanism from the node author.

Make node flags have a consistent style in naming.
