Revert "rt2800pci: handle spurious interrupts"

2011-11-22T21:38:19+00:00

This reverts commit 4ba7d9997869d25bd223dea7536fc1ce9fab3b3b.

The original patch was a misguided attempt to improve performance on
some hardware that is apparently prone to spurious interrupt generation.

rt2x00: handle spurious pci interrupts

2011-11-17T19:39:30+00:00

We have documented case of very bad performance issue on rt2800pci
device, because it generate spurious interrupt, what cause irq line
is disabled: https://bugzilla.redhat.com/show_bug.cgi?id=658451

We already address that problem in separate patch by returning
IRQ_HANDLED from interrupt handler. We think similar fix is needed for
other rt2x00 PCI devices, because users report performance problems on
these devices too.

rt2800pci: handle spurious interrupts

2011-11-17T19:39:30+00:00

Some devices may generate spurious interrupts, we have to handle them
otherwise interrupt line will be disabled with below message and driver
will not work:

rt2x00: Fix sleep-while-atomic bug in powersaving code.

2011-11-15T15:02:56+00:00

The generic powersaving code that determines after reception of a frame
whether the device should go back to sleep or whether is could stay
awake was calling rt2x00lib_config directly from RX tasklet context.
On a number of the devices this call can actually sleep, due to having
to confirm that the sleeping commands have been executed successfully.

Fix this by moving the call to rt2x00lib_config to a workqueue call.

This fixes bug https://bugzilla.redhat.com/show_bug.cgi?id=731672

mac80211: pass vif param to conf_tx() callback

tx params should be configured per interface.
add ieee80211_vif param to the conf_tx callback,
and change all the drivers that use this callback.

The following spatch was used:
