253af4235d [NET]: Add IFB (Intermediate Functional Block) network device.
A new device to do intermidiate functional block in a system shared
manner.  To use the new functionality, you need to turn on
qos/classifier actions.

The new functionality can be grouped as:

1) qdiscs/policies that are per device as opposed to system wide.  ifb
allows for a device which can be redirected to thus providing an
impression of sharing.

2) Allows for queueing incoming traffic for shaping instead of
dropping.

Packets are redirected to this device using tc/action mirred redirect
construct. If they are sent to it by plain routing instead then they
will merely be dropped and the stats would indicate that.

15d014d131 [PATCH] intel ixp2000 network driver
The way the hardware and firmware work is that there is one shared RX
queue and IRQ for a number of different network interfaces.  Due to this,
we would like to process received packets for every interface in the same
NAPI poll handler, so we need a pseudo-device to schedule polling on.

What the driver currently does is that it always schedules polling for
the first network interface in the list, and processes packets for every
interface in the poll handler for that first interface -- however, this
scheme breaks down if the first network interface happens to not be up,
since netif_rx_schedule_prep() checks netif_running().

sky2 apparently has the same issue, and Stephen Hemminger suggested a
way to work around this: create a variant of netif_rx_schedule_prep()
that does not check netif_running().  I implemented this locally and
called it netif_rx_schedule_prep_notup(), and it seems to work well,
but it's something that probably not everyone would be happy with.

The ixp2000 is an ARM CPU with a high-speed network interface in the
CPU itself (full duplex 4Gb/s or 10Gb/s depending on the IXP model.)
The CPU package also contains 8 or 16 (again depending on the IXP
model) 'microengines', which are somewhat primitive but very fast
and efficient processor cores which can be used to offload various
things from the main CPU.

This driver makes the high-speed network interface in the CPU visible
and usable as a regular linux network device.  Currently, it only
supports the Radisys ENP2611 IXP board, but adding support for other
board types should be fairly easy.

b3f9b92a6e [PPP]: add PPP MPPE encryption module
From: Matt Domsch <Matt_Domsch@dell.com>

The patch below implements the Microsoft Point-to-Point Encryption method
as a PPP compressor/decompressor.  This is necessary for Linux clients and
servers to interoperate with Microsoft Point-to-Point Tunneling Protocol
(PPTP) servers (either Microsoft PPTP servers or the poptop project) which
use MPPE to encrypt data when creating a VPN.

This patch differs from the kernel_ppp_mppe DKMS pacakge at
pptpclient.sourceforge.net by utilizing the kernel crypto routines rather
than providing its own SHA1 and arcfour implementations.

Minor changes to ppp_generic.c try to prevent a link from disabling
compression (in our case, the encryption) after it has started using
compression (encryption).

Feedback to <pptpclient-devel@lists.sourceforge.net> please.

aaec0fab5f [PATCH] net: add driver for the NIC on Cell Blades
This patch adds a driver for a new 1000 Mbit ethernet NIC.  It is
integrated on the south bridge that is used for our Cell Blades.

The code gets the MAC address from the Open Firmware device tree, so it
won't compile on platforms other than ppc64.

This is the first public release, so I don't expect the first version to
get merged, but I'd aim for integration within the 2.6.13 time frame.

cd28ab6a4e [PATCH] sky2: new experimental Marvell Yukon2 driver
New driver for the Marvell Yukon2 Gigabit Ethernet chipset.
This driver is based on the skge driver, but using the logic
from the SysKonnect version of the sk98lin driver.
It should support all the Yukon2 chipsets that are available
in many current Intel and AMD motherboards.

The driver does support ethtool, tx and rx checksum, and
tcp segmentation offload.  But it has only been tested for
a short while and is known to stop receiving under heavy load.

890e8d0a3d [PATCH] sis190: resurrection
Raise the sis190 driver from the dead

The driver handles the integrated network device found on SiS 965L
chipset. It follows the classical (non-napi) interrupt-driven model
and provides minimal ethtool support.

The code comes from a heavy cleanup/rewrite of the original code
which was removed from the kernel on 14/04/2004. Since the r8169
driver does not work too bad and there will probably be (at least)
a few months of improvements/testing/fixing, I made the code as
close as possible to the r8169 one.

Pascal Chapperon <pascal.chapperon@wanadoo.fr> deserves some special
credit for testing and bug-catching. Many thanks to Lars Vahlenberg
as well.

The performance recommendations in cxgb.txt are common to all fast devices,
and should be in one file rather than just for this device. I would rather
see ip-sysctl.txt updated or a new file on tuning recommendations started.
Some of them have consequences that aren't documented well.
For example, turning off TCP timestamps risks data corruption from sequence wrap.

A new driver shouldn't need so may #ifdef's unless you want to putit on older
vendor versions of 2.4

Some accessor and wrapper functions like:
        t1_pci_read_config_4
        adapter_name
        t1_malloc
are just annoying noise.

Why have useless dead code like:

/* Interrupt handler */
+static int pm3393_interrupt_handler(struct cmac *cmac)
+{
+       u32 master_intr_status;
+/*
+    1. Read master interrupt register.
+    2. Read BLOCK's interrupt status registers.
+    3. Handle BLOCK interrupts.
+*/

Jeff said:

step 1:  kill all the OS wrappers.

 And do you really need hooks for multiple MACs, when only one MAC is
 really supported?  Typically these hooks are at a higher level anyway --
 struct net_device.

From: Christoph Lameter <christoph@lameter

Driver modified as suggested by Pekka Enberg, Stephen Hemminger and Andrian
Bunk.  Reduces the size of the driver to ~260k.

- clean up tabs
- removed my3126.c
- removed 85% of suni1x10gexp_regs.h
- removed 80% of regs.h
- removed various calls, renamed variables/functions.
- removed system specific and other wrappers (usleep, msleep)
- removed dead code
- dropped redundant casts in osdep.h
- dropped redundant check of kfree
- dropped weird code (MODVERSIONS stuff)
- reduced number of #ifdefs
- use kcalloc now instead of kmalloc
- Add information about known issues with the driver
- Add information about authors

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.
