Arnaldo Carvalho de Melo 459a98ed88 [SK_BUFF]: Introduce skb_reset_mac_header(skb)
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can
later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.

Jeff Morrow 52edc17f94 bugfixes and new hardware support for arcnet driver
The modifications and bug fixes noted below were done by Realtime Control
Works and Contemporary Control Systems, Inc, Jan 2005.  They were
incorporated into the 2.6 kernel by Jeff Morrow of Sierra Analytics, Feb
2007.  <jmorrow@massspec.com>

The changes have been tested on a Contemporary Controls PCI20U-4000.

Summary of changes:

Arc-rawmode.c:
      rx():
      - Fixed error in received packet lengths; 256 byte packets were
        being received as 257 bytes packets.

      prepare_tx():
      - Fixed error in transmit length calcs; 257 byte packets were being
        transmitted as 260 byte packets.

com20020.c:
      com20020_check():
      - We now load the SETUP2 register if the 'clockm' parameter is
        non-zero, instead of checking for ARC_CAN_10MBIT. The user is
        now responsible for whether or not SETUP2 is loaded.  If the
        clock multiplier is non-zero, this means that the user wants a
        baud rate greater than 2.5Mbps. This is not possible unless the
        SETUP2 register is present (COM20020D, or COM20022). So, we're
        relying on the user to be smart about what kind of chip he's
        dealing with...

com20020-pci.c
      - Added several entries to com20020pci_id_table[].

Adrian Bunk f03aa2d89a [PATCH] drivers/net/arcnet/: possible cleanups
This patch contains the following possible cleanups:
- make needlessly global code static
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arc_proto_null)
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arcnet_dump_packet)

To make Jeff happy, arcnet.c still prints
  arcnet: v3.93 BETA 2000/04/29 - by Avery Pennarun et al.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
