Patch does following things
1) This patch fixes the a-band association for passive channels with new
uCode feature that it allows direct scan on passive channels after
auto-switch from passive to active. This enables sending of direct probes
on passive channels, as long as some traffic is detected on that channel.
This improves the scanning for hidden SSIDs in A-band,which is all
passive channels.
This patch fixes the bug no 1748.
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748
2) This fix will only work with uCode version 15.28.2.8 and above.
Prior versions of uCode would work only if we heard the traffic within
active dwell time, which is much shorter than passive dwell time and
is shorter than typical beacon periods. This patch also provids full
active dwell time even if we hear traffic late in passive dwell.
3) uCode API version is incremented to 2.

This adds the infrastructure to support older firmware APIs.
The API version number is stored as part of the filename, we first try to
load the most recent firmware and progressively try lower versions.
The API version is also read from the firmware self and stored as part
of the iwl_priv structure. Only firmware that is supported by driver will
be loaded. The version number read from firmware is compared
to supported versions in the driver not the API version used as part of
filename.
An example using this new infrastrucure:
if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
Driver interacts with Firmware API version >= 2.
} else {
Driver interacts with Firmware API version 1.

Bring the physical link down when the interface is down by placing the PHY
in power-down state, unless WOL is enabled. This mirrors the behavior of
other drivers including e1000 and tg3.
Without the patch, ifconfig down leaves the physical link up, which confuses
datacenter users who expect the link lights both on the NIC and the switch to
go out when they bring an interface down.
Furthermore, even though the phy is powered on, autonegotiation stops working,
so a normally gigabit link might suddenly become 100 Mbit half-duplex when the
interface goes down, and become gigabit when it comes up again.
Ayaz said:
I would not include this patch until further testing is performed. NVIDIA
MCP chips use 3rd party PHY vendors. By powering down the phy, it could
have adverse affects on certain phys.

I just ran across this patch. Tested on a Marvell 88E1121R (GigE PHY)
and works great. This is a very important feature for me.

ifa_local is assumed to be unsigned long which lead to writing the address
at dev->dev_addr-2 instead of +2
noticed thanks to gcc:

ARRAY_SIZE is more concise to use when the size of an array is divided by
the size of its type or the size of its first element.
The semantic patch that makes this change is as follows:

Simply use netdev_priv() to replace netdev->priv.

Usually, netdev->priv should point to the memory of private
data which is allocated in alloc_netdev().
netdev_priv() is used to get the address of the private data.
Change the netdev->priv pointer to another memory is wrong.
Use netdev->ml_priv for this case.

The bnx2 chips do not support per MSI vector masking. On 5706/5708, new MSI
address/data are stored only when the MSI enable bit is toggled. As a result,
SMP affinity no longer works in the latest kernel. A more serious problem is
that the driver will no longer receive interrupts when the MSI receiving CPU
goes offline.
The workaround in this patch only addresses the problem of CPU going offline.
When that happens, the driver's timer function will detect that it is making
no forward progress on pending interrupt events and will recover from it.
Eric Dumazet reported the problem.
We also found that if an interrupt is internally asserted while MSI and INTA
are disabled, the chip will end up in the same state after MSI is re-enabled.
The same workaround is needed for this problem.

If xpc.ko and gru.ko are both statically linked into the kernel, then
xpc_init() can get called before gru_init() and make a call to one of the
gru's exported functions before the gru has initialized itself. The end
result is a NULL dereference.

It seems that on some nVidia controllers using AltStatus register
can be unreliable so default to Status register if the PCI device
is in Compatibility Mode. In order to achieve this:
* Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>.
* Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host
driver for nVidia controllers in Compatibility Mode.
* Teach actual_try_to_identify() and drive_is_ready() about the new flag.
This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ
config option in 2.6.25 and using AltStatus register unconditionally when
available (kernel.org bugs #11659 and #10216).
[ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people
and distributions use) it never worked correctly. ]
Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.
