As previously reported the ArcNet driver didn't work with Preempt and SMB
on.  They do now.  I have changed the locking system from being a global
arcnet lock to being a lock per device.  I used the lock in
dev->hard_start_xmit = arcnet_send_packet.  

Furthermore I added the 'CAP mode' encapsulation.  As far as I see it it is
the only encapsulation which actually makes ArcNet usefull over ethernet. 
Previously, the driver just ignored the hardware transmit status, now you
can get hardware acknowledge and excessive nacks back to userspace via a
raw socket.  The capmode.c is nearly just a copy of arc-rawmode.c.  The
difference is that it inserts a ack_tx() handle into the general driver
framework.

The patch below adds the ebtables ulog watcher, that sends packets
to userspace. It is based on ipt_ULOG.c.

The complete packet, including Ethernet header, is sent to userspace.
The in and out bridge ports are also sent to userspace. Logging is
of course not restricted to IP packets.
An example of a userspace program that receives and parses packets
sent by the ulog watcher is in the ebtables CVS tree under
examples/ulog/

Some architectures can optimize local_softirq_pending much better than
softirq_pending(smp_processor_id()), and for all others the former is
just a macro expanding to the later.

Also this is the last use of softirq_pending() in common code, once this
is in we can soon kill the notation of beeing able to query other cpus
softirq pending count.

After the last patch only three routines are left in this file, but all
of the fir into net/core/dev.c much better:

 - {un,}register_netdev are just wrappers around {un,}register_netdevice
   from dev.c
 - alloc_netdev's counterpart, free_netdev is in dev.c aswell.

So move over the remaining contents and add some kerneldoc comments
describing the functions.

This serves two purposes: firstly, we like to allocate page-sized skbs
as this means we zero-copy transfer of network buffers between guest
operating systems. Secondly, it enables us to have a cache of pages
that have been used for network buffers that we can be more lax about
scrubbing when they change VM ownership (since they could be sniffed on
the wire).

When I switched my installation from kernel 2.4 to 2.6 I recognized that
the ISDN module dss1_divert was marked incompilable (config option
CONFIG_CLEAN_COMPILE must be turned off). 

The compile problem was the obsolete using of kernel 2.4 critical
sections.  I replaced the cli() stuff with spinlocks as explained in the
Documentation/spinlocks.txt file.  After that the module compiles and
runs as expected.
