df5e198723 Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

COMPAT_ISA_DRIVER() so that we can get rid of the evil isa_compat.h table.

49ce7a6052 Make the N2 isa cards probe again. Remove the unused frame relay hooks.
This should also fix PR 17814 where flags were ignored on the first
usage of ifconfig on the interface.

and if_ar drivers, and PPPOE support soon. See:

46783fb897 Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

579f45fa60 Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

1d5e9e2255 Make INET a proper option.
This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway.  Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug.  The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

This commit move struct arpcom from <netinet/if_ether.h> to
<net/if_arp.h>.

00081cc989 Major overhaul of the SyncPPP layer. Basically, this comprises now a
full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols.  I needed
this to provide PPP support for the BISDN project (right now).

Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer.  This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events).  Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles.  Please report if i broke
something in the existing drivers.

For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

75c66a120a if_sr.c corrupted the global variable `ticks'.
Cosmetic changes:
if_sr_.c won't compile with a K&R compiler, so there is no need to cast
the timeout arg to the (wrong) type.

d805b866fa This driver supports the SDL Communications RISCom/N2 ISA cards that is
based on the HD64570 chip. Both the 1 and 2 port cards is supported.

Line speeds of up to 2Mbps is possible. At this speed about 95% of the
bandwidth is usable with 486DX processors.

The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.

At the moment only the X.21 interface is tested. The others may need
tweaks to the clock selection code.
