OK, updated patch below.

- it's unused
- the struct can become static without the EXPORT_SYMBOL


<--  snip  -->


This patch contains the following possible cleanups:
- make needlessly global code static
- arcnet.c: remove the outdated VERSION
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arc_proto_null)
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arcnet_dump_packet)
