ARCnet "cap mode" packet encapsulation. Used to get the hardware
acknowledge back to userspace. After the initial protocol byte every
packet is stuffed with an extra 4 byte "cookie" which doesn't
actually appear on the network. After transmit the driver will send
back a packet with protocol byte 0 containing the status of the
transmition:
0=no hardware acknowledge
1=excessive nak
2=transmition accepted by the reciever hardware
Received packets are also stuffed with the extra 4 bytes but it will
be random data.
Cap only listens to protocol 1-8.

/*
* Linux ARCnet driver - "cap mode" packet encapsulation.
* It adds sequence numbers to packets for communicating between a user space
* application and the driver. After a transmit it sends a packet with protocol
* byte 0 back up to the userspace containing the sequence number of the packet
* plus the transmit-status on the ArcNet.
*
* Written 2002-4 by Esben Nielsen, Vestas Wind Systems A/S
* Derived from arc-rawmode.c by Avery Pennarun.
* arc-rawmode was in turned based on skeleton.c, see below.

This file contains the initialization for the "pl14+" style ethernet
drivers. It should eventually replace most of drivers/net/Space.c.
It's primary advantage is that it's able to allocate low-memory buffers.
A secondary advantage is that the dangerous NE*000 netcards can reserve
their I/O port region before the SCSI probes start.
Modifications/additions by Bjorn Ekwall <bj0rn@blox.se>:
ethdev_index[MAX_ETH_CARDS]
register_netdev() / unregister_netdev()
Modifications by Wolfgang Walter
Use dev_close cleanly so we always shut things down tidily.
Changed 29/10/95, Alan Cox to pass sockaddr's around for mac addresses.
14/06/96 - Paul Gortmaker: Add generic eth_change_mtu() function.
24/09/96 - Paul Norton: Add token-ring variants of the netdev functions.
08/11/99 - Alan Cox: Got fed up of the mess in this file and cleaned it
up. We now share common code and have regularised name
allocation setups. Abolished the 16 card limits.
03/19/2000 - jgarzik and Urban Widmark: init_etherdev 32-byte align
03/21/2001 - jgarzik: alloc_etherdev and friends

/* The network devices currently exist only in the socket namespace, so these

open start the ethercard
close stop the ethercard
ioctl To get statistics, perhaps set the interface port (AUI, BNC, etc.)
One can also imagine getting raw packets using
read & write
but this is probably better handled by a raw packet socket.
Given that almost all of these functions are handled in the current
socket-based scheme, putting ethercard devices in /dev/ seems pointless.

This option adds the ulog watcher, that you can use in any rule

logging daemon using netlink multicast sockets. This differs
from the log watcher in the sense that the complete packet is
sent to userspace instead of a descriptive text and that
netlink multicast sockets are used instead of the syslog.

/*
* netfilter module for userspace bridged Ethernet frames logging daemons
*
* Authors:
* Bart De Schuymer <bdschuym@pandora.be>
*
* November, 2004
*
* Based on ipt_ULOG.c, which is
* (C) 2000-2002 by Harald Welte <laforge@netfilter.org>
*
* This module accepts two parameters:
*
* nlbufsiz:
* The parameter specifies how big the buffer for each netlink multicast
* group is. e.g. If you say nlbufsiz=8192, up to eight kb of packets will
* get accumulated in the kernel until they are sent to userspace. It is
* NOT possible to allocate more than 128kB, and it is strongly discouraged,
* because atomically allocating 128kB inside the network rx softirq is not
* reliable. Please also keep in mind that this buffer size is allocated for
* each nlgroup you are using, so the total kernel memory usage increases
* by that factor.
*
* flushtimeout:
* Specify, after how many hundredths of a second the queue should be
* flushed even if it is not full yet.
*
