The large receive buffer queue is not properly tracking the current
index in the case where an early exit occurs. This can happen when a
page alloc or dma mapping fails. If this occurs the queue will get
out of sync and invalid indexes can be written to the hardware.

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.

new packets. If the allocation fails, ath5k_tasklet_rx will exit but
will leave a buffer in the list with a NULL skb, eventually triggering
a BUG_ON.
Extract the skb allocation from ath5k_rxbuf_setup() and change the
tasklet to allocate the next skb before accepting a packet.

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
initialization for whatever reason - IRQ is registered and OOPS happens
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.
Tested on E450 with PCI HME and PCI Quad HME.

RXSEQ interrupts were used to force link state interrogation of serdes
links, as the Si was not guaranteed to report LSC interrupts when the
link changed state. On some bladeservers this resulted in false link up
reports if no link partner was connected. The RXSEQ treatment is
not necessary, as the link can be monitored from the watchdog timer, and
the false link indications cease.

82571 and 82572 Errata #13 documents that the Si feature DMA Dynamic
Clock Gating should be disabled, and identifies the workaround of
disabling the feature by EEPROM setting. EEPROM versions that do not
include the recommended workaround have been found in the field, and so
some customers remain at risk. Because the feature DMA Dynamic clock
Gating can be disabled by directly setting the appropriate bit in the
E1000_CTRL_EXT register, this patch overrides the EEPROM setting, and
force-disables the feature.
