Bit-field constants in zd_chip.h are now defined using a shift expression.
The value 0x08 is now (1 << 3). The fix is intended to improve readability.

Remove misleading comment in zd_mac.c: The function already returns -EPERM
in managed mode (IW_MODE_INFRA).

Remove unused code in zd_mac.c: The unused code intended for debugging
rx_status values is no longer useful.

Added dump_stack() to ZD_ASSERT macro: Output of the stack helps to debug
assertions. Keep in mind that the ZD_ASSERT() macro only results in code,
if DEBUG is defined.

Daniel Drake 84bc715c46 [PATCH] zd1211rw: Remove IW_FREQ_AUTO support
http://bugzilla.kernel.org/show_bug.cgi?id=7399

zd1211rw's support for IW_FREQ_AUTO is broken: when specified, the driver
tries to change to a channel specified in an uninitialized integer. As
IW_FREQ_AUTO is hard to implement properly, the solution (at least for now)
is to drop support for it and start ignoring the flags like all other wireless
drivers do.

This has the added advantage that kismet also starts working with zd1211rw,
even though kismet requesting IW_FREQ_AUTO is also a bug (fixed in their svn)

Haavard Skinnemoen 89e5785fc8 [PATCH] Atmel MACB ethernet driver
Driver for the Atmel MACB on-chip ethernet module.

Tested on AVR32/AT32AP7000/ATSTK1000. I've heard rumours that it works
with AT91SAM9260 as well, and it may be possible to share some code with
the at91_ether driver for AT91RM9200.

Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from

http://www.atmel.com/dyn/products/datasheets.asp?family_id=682

Changes since previous version:
  * Probe for PHY ID instead of depending on it being provided through
    platform_data.
  * Grab initial ethernet address from the MACB registers instead
    of depending on platform_data.
  * Set MII/RMII mode correctly.

These changes are mostly about making the driver more compatible with
the at91 infrastructure.

Zang Roy-r61911 5e123b844a [PATCH] Add tsi108/9 On Chip Ethernet device driver support
Add tsi108/9 on chip Ethernet controller driver support.

The driver code collects the feedback of previous posting form the mailing
list and gives the update.

MPC7448HPC2 platform in arch/powerpc uses tsi108 bridge.

The following is a brief description of the Ethernet controller:

The Tsi108/9 Ethernet Controller connects Switch Fabric to two independent
Gigabit Ethernet ports,E0 and E1.  It uses a single Management interface to
manage the two physical connection devices (PHYs).  Each Ethernet port has
its own statistics monitor that tracks and reports key interface
statistics.  Each port supports a 256-entry hash table for address
filtering.  In addition, each port is bridged to the Switch Fabric through
a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO.

Each Ethernet port also has a pair of internal Ethernet DMA channels to
support the transmit and receive data flows.  The Ethernet DMA channels use
descriptors set up in memory, the memory map of the device, and access via
the Switch Fabric.  The Ethernet Controller’s DMA arbiter handles
arbitration for the Switch Fabric.  The Controller also has a register bus
interface for register accesses and status monitor control.

The PMD (Physical Media Device) interface operates in MII, GMII, or TBI
modes.  The MII mode is used for connecting with 10 or 100 Mbit/s PMDs.
The GMII and TBI modes are used to connect with Gigabit PMDs.  Internal
data flows to and from the Ethernet Controller through the Switch Fabric.
Each

Ethernet port uses its transmit and receive DMA channels to manage data
flows through buffer descriptors that are predefined by the system (the
descriptors can exist anywhere in the system memory map).  These
descriptors are data structures that point to buffers filled with data
ready to transmit over Ethernet, or they point to empty buffers ready to
receive data from Ethernet.

Larry Finger 08c3103a56 [PATCH] bcm43xx: remove badness variable and related routine
When the periodic work function in bcm43xx was converted for voluntary preemption
to reduce latency, a new function was created to estimate the "badness" of
each step, and this quantity was used to determine if preemption should be
enabled when periodic work was undertaken. This concept was quite useful
while debugging of periodic work was in progress. Now that this routine
seems to be working correctly, it is time to simplify the code. This
patch keeps the functionality intact, but simplifies the code.

Jesse Brandeburg 835bb12983 e1000: add dynamic itr modes
Add a new dynamic itr algorithm, with 2 modes, and make it the default
operation mode. This greatly reduces latency and increases small packet
performance, at the "cost" of some CPU utilization. Bulk traffic
throughput is unaffected.

The driver can limit the amount of interrupts per second that the
adapter will generate for incoming packets. It does this by writing a
value to the adapter that is based on the maximum amount of interrupts
that the adapter will generate per second.

Setting InterruptThrottleRate to a value greater or equal to 100 will
program the adapter to send out a maximum of that many interrupts per
second, even if more packets have come in. This reduces interrupt
load on the system and can lower CPU utilization under heavy load,
but will increase latency as packets are not processed as quickly.

The default behaviour of the driver previously assumed a static
InterruptThrottleRate value of 8000, providing a good fallback value
for all traffic types,but lacking in small packet performance and
latency. The hardware can handle many more small packets per second
however, and for this reason an adaptive interrupt moderation algorithm
was implemented.

Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in
which it dynamically adjusts the InterruptThrottleRate value based on
the traffic that it receives. After determining the type of incoming
traffic in the last timeframe, it will adjust the InterruptThrottleRate
to an appropriate value for that traffic.

The algorithm classifies the incoming traffic every interval into
classes.  Once the class is determined, the InterruptThrottleRate
value is adjusted to suit that traffic type the best. There are
three classes defined: "Bulk traffic", for large amounts of packets
of normal size; "Low latency", for small amounts of traffic and/or
a significant percentage of small packets; and "Lowest latency",
for almost completely small packets or minimal traffic.

In dynamic conservative mode, the InterruptThrottleRate value is
set to 4000 for traffic that falls in class "Bulk traffic". If
traffic falls in the "Low latency" or "Lowest latency" class, the
InterruptThrottleRate is increased stepwise to 20000. This default
mode is suitable for most applications.

For situations where low latency is vital such as cluster or
grid computing, the algorithm can reduce latency even more when
InterruptThrottleRate is set to mode 1. In this mode, which operates
the same as mode 3, the InterruptThrottleRate will be increased
stepwise to 70000 for traffic in class "Lowest latency".

Setting InterruptThrottleRate to 0 turns off any interrupt moderation
and may improve small packet latency, but is generally not suitable
for bulk throughput traffic.

Jeff Kirsher 2df7d59f28 e1000: rename ICH8 flash macros
ICH8 will soon be followed by newer chipsets bearing the same acronym,
thus we remove the '8' and make it independent of the version number in
