This patch sets the compressed BA handler for 5000. This allows the rate
scaling algorithm to take in count frames that were sent in AMPDUs.
The compressed BA handler has been moved to iwl-rx.c since it is common to
4965 and 5000.

The iwlwifi drivers go to great lengths to avoid passing packets to
mac80211 they think shouldn't go there, while mac80211 can (of course!)
handle them very well.
Especially in the case of duplicate packets this is interesting
because it's such a performance hog (especially for IBSS networks)
while mac80211 does that work on the side without much effort.
This patch removes all that and leaves only what is absolutely
necessary for the hardware.

This patch fixes a bug in association flow. As soon as RXON with assoc bit
is sent, uCode expects to have an entry in its station table that describe
the AP. Receiving a beacon from an HT AP before sending ADD_STA results a
uCode error. This patch sends first the ADD_STA (bcast and bssid) and only
then RXON with assoc bit set

This patch makes the station table maintenance safer. Two flags are
maintained:
1) if station is present in driver
2) if station is present in uCode
This will allow us in the future to deal with more stations than the
firmware allows.

We currently don't signal the kernel we that this device can wake
the system. Call device_init_wakeup() to correct this.
Without this device_can_wakeup and device_may_wakeup will return
incorrect values.
Together with the minimized acpi wakeup patch (6/4 ;)), which will
follow in the next mail, this really makes wake-on-lan work for me
as expected (i.e. "ethtool -s eth0 wol g" is sufficient, no
additional magic needed).

The call to e1000_clean_tx_irq in e1000_netpoll can race with the call
to e1000_clean_tx_irq in e1000_clean. With a small bit of tweaking to
to netpoll_send_skb to simulate a system that was under extreme stress,
I was able to reproduce these concurrent calls. This can result in
multiple frees to the skbs on the tx ring buffer.
Dropping this call from e1000_netpoll should be fine since we can rely
on the calls in e1000_clean to do what is needed since napi will poll
the hardware just after calling poll_controller.

This fixes a circular locking dependency in the workqueue handling.
The interface work task uses the mac80211 function
ieee80211_iterate_active_interfaces() which grabs the RTNL lock.
However when the interface is brough down, this happens under the RTNL
lock as well, this causes problems because mac80211 will flush the workqueue
during the ifdown event. This causes mac80211 to wait until the driver has
completed all work which can't finish because it is waiting on the RTNL lock.
This is fixed by moving rt2x00 workqueue tasks on a different workqueue,
this workqueue can be flushed when the ieee80211_hw structure is removed
by the driver (when the driver is unloaded) which does not happen under the
RTNL lock.

When rt2x00queue_alloc_rxskbs() fails rt2x00queue_unitialize()
will be called which will free all rxskb. So we don't need
to do this in the rt2x00queue_alloc_rxskb() function as well.
rt2x00queue_free_skb() unmaps the DMA but doesn't clear the
allocation flag. Since the code is copied from rt2x00queue_unmap_skb()
anyway (and that function does clear the flag) we might as well
use that function directly.

This adds a firmware debugging knob to debugfs.
With this knob it's possible to enable advanced runtime firmware

In future there'll probably be more.

This is a rewrite of the DMA API for SSB devices.
This is needed, because the old (non-existing) "API" made too many bad

This introduces an almost complete SSB-DMA-API that maps to the lowlevel
bus-API based on the bustype.

s2io has IOMMU overflow checking, but unfortunately it is wrong.
It didn't use the standard macros, which meant that it only worked
on POWER and SPARC because only those define DMA_ERROR_CODE. Convert it to
use the standard macros instead.
I also commented two more bugs in the IOMMU handling. It assumes
that 0 DMA addresses cannot happen, but that's not true in all IOMMU setups.
The information if a buffer has been already mapped needs to be stored
elsewhere.
Didn't fix those because it needs careful checking of the buffer handling
by the maintainers.
