    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.
