wimax/i2400m: driver loads firmware v1.4 instead of v1.3
This is a one liner change to have the driver use by default the v1.4
of the i2400m firmware instead of v1.3. The v1.4 version of the
firmware has been submitted to David Woodhouse for inclusion in the
linux-firmware tree and it is already available at
http://linuxwimax.org/Download.
The reason for this change is that the 1.3 release of the user space
software and firmware has a few issues that will make it difficult to
use with currently deployed commercial networks such as Xohm and
Clearwire.
As well, the new 1.4 release of the user space software (which matches
the 1.4 firmware) has intermitent issues with the 1.3 firmware.
The 1.4 release in http://linuxwimax.org/Download has been widely
deployed and tested with the codebase in 2.6.29-rc, the 1.4 firmware
and the 1.4 user space components.
We understand it is quite late in the rc process for such a change,
but would like to ask for the change to be taken into consideration.
Alternatively, a user could always force feed a 1.4 firmware into a
driver that doesn't have this modification by:
net/mv643xx: don't disable the mib timer too early and lock properly
mib_counters_update() also restarts the timer.
So the timer is dequeued, the stats are read and then the timer is
enqueued again. This is "okay" unless someone unloads the module.
The locking here is also broken:
mib_counters_update() grabs just a simple spinlock. The only thing the
lock is good for is to protect the timer func against other callers
namely mv643xx_eth_stop() && mv643xx_eth_get_ethtool_stats(). That means
if the spinlock is taken via the ethtool path and than the timer kicks
in then the box will lock up.

Solve both these problems by switching to in_interrupt(). Now, if someone

iwlwifi: fix suspend/resume and its usage of pci saved state
Here we do two things:
First, revert "iwlwifi: save PCI state before suspend, restore after
resume". That misguided patch led to being unable to use iwlwifi
devices after resume.
Next, indicate to PCI driver that the saved PCI state is valid during suspend.
We restore PCI state and enable the device when network interface is created,
similarly PCI state is saved and the device is disabled when network interface
is removed. Thus, when .suspend is called the PCI state is saved and device
is disabled. This is the case even if an interface is never created as PCI
state is saved and device disabled during .probe.
PCI driver assumes PCI state is saved in .suspend. Saving the state at this
time will save state of disabled device and thus cause problems during
resume (resuming a disabled device). We thus indicate directly to PCI
driver that current PCI saved state is valid.

Currently, the sunhme driver installs SBus Quattro interrupt handler
when at least one HME card was initialized correctly and at least one
Quattro card is present. This breaks when a Quattro card fails

when it fires.
The solution, as suggested by David Miller, was to keep track which
cards of the Quattro bundles have been initialized, and request/free the
Quattro IRQ only when all four devices have been successfully
initialized.
The patch only touches SBus initialization - PCI init already resets the
card pointer to NULL on init failure.
The patch has been tested on Sun E3500 with SBus and PCI single HME
cards and one PCI Quattro HME card in a situation where any PCI card
failed init when the SBus routines tried to init them by mistake.
Additionally it replaces Quattro request_irq panic with error return -
if this card fails to work, at least let the others work.

When the changes were done to the protocol last release, some endian
bugs crept in. This patch fixes those endian problems and has been
verified to run on 32/64 bit and x86/ppc architectures.
This version of the patch incorporates the correct annotations
for endian variables.

3c509: Fix resume from hibernation for PnP mode.
From: Ondrej Zary <linux@rainbow-software.org>
last year, I posted a patch which fixed hibernation on 3c509
cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I
stopped using hibernation (as it did not work with my new IT8212 RAID
controller).
Now I fixed it and noticed that 3c509 does not wake up properly
anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig
down/up makes the card work again in PnP mode. However, in ISA mode,
ifconfig up ends with "No such device" error.
Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only
some statistics-related change. So the cause of the problem must be
somewhere else.
This patch makes the resume work in PnP mode, but it's still not
enough for ISA mode.

sungem: Soft lockup in sungem on Netra AC200 when switching interface up
From: Ilkka Virta <itvirta@iki.fi>
In the lockup situation the driver seems to go off in an eternal storm
of interrupts right after calling request_irq(). It doesn't actually
do anything interesting in the interrupt handler. Since connecting the link
afterwards works, something later in initialization must fix this.
Looking at gem_do_start() and gem_open(), it seems that the only thing
done while opening the device after the request_irq(), is a call to
napi_enable().
I don't know what the ordering requirements are for the
initialization, but I boldly tried to move the napi_enable() call
inside gem_do_start() before the link state is checked and interrupts
subsequently enabled, and it seems to work for me. Doesn't even break
anything too obvious...

r8169: Don't update statistics counters when interface is down
Some Realtek chips (RTL8169sb/8110sb in my case) are unable to retrieve
ethtool statistics when the interface is down. The process stays in
endless loop in rtl8169_get_ethtool_stats. This is because these chips
need to have receiver enabled (CmdRxEnb bit in ChipCmd register) that is
cleared when the interface is going down. It's better to update statistics
only when the interface is up and otherwise return copy of statistics
grabbed when the interface was up (in rtl8169_close).
It is interesting that PCI-E NICs (like 8168b/8111b...) are not affected.
