reviewed beacon timer initialization with register traces from madwifi: what we
are doing is correct :). one minor fix: use 3 instead of 0x00000003 - it's more
readable.

This zeros out all microcode related memory before loading
the microcode.
This also fixes initialization of the MAC control register.
The _only_ place where we overwrite the contents of the MAC control
register is at the beginning of b43_chip_init().
All other places must do read() -> mask/set -> write() to not
overwrite existing bits.
This also adds a longer delay for waiting for the microcode
to initialize itself. It seems that the current timeout is sufficient
on all available devices, but there's no real reason why we shouldn't
wait for up to one second. Slow embedded devices might exist.
Better safe than sorry.

After we delay device initialization until interface up, there are more
conditions for the hardware rf_kill switch states during suspend and
resume. For example, before suspend we can have interface up or down,
rf_kill enable or disable; before resume we can have rf_kill enable or
disable. So there are totally 2^3 = 8 conditions to handle. This patch
addressed this problem and makes sure every condition works correctly.
This patch also merges the device suspend and resume handlers with the
mac_start and mac_stop code since they are basically doing the same
thing.

This patch moves the firmware loading (read firmware from disk and load
it into the device SRAM) from pci_probe time to the first network
interface open time. There are two reasons for doing this:
1. To support kernel buildin iwlwifi drivers. Because kernel initializes
network devices subsystem before hard disk and SATA subsystem, it is
impossible to get the firmware image from hard disk in the PCI probe
handler. Thus delaying the firmware loading into the network
interface open time is the way to go. Note, we only read the firmware
image from hard disk the first time the interface is open. After this
is succeeded, we cache the firmware image into the host memory. This
is a performance gain when user open and close the interface multiple
times and is necessary for device suspend and resume.
2. For better power saving. When the iwlwifi modules are loaded (or
buildin the kernel) but the wireless network interface is not being
used, it is a good practice the wireless device consumes as less
power as possible. Unloading the firmware from the wireless device
and unregister the driver's interrupt handler in the network
interface close handler provides users a way to achieve this. User
space network configuration tools (i.e NetworkManager) can also
contribute here when it detects a wired cable is connected and
close the wireless interface automatically.
This patch also includes the pci_save/restore_state() fixed by Ian Schram
upon the first version.

rt2500usb and rt73usb data and desc pointer initialization
was incorrect because it was using uninitialized variables
to determine the length.
In addition rt2500usb used skb_pull and removed the ieee80211
from each received frame instead of using skb_trim to remove
the device descriptor from the frame.
Finally this also fixes the descriptor override when 4 byte
aligning occured. We still need a completely valid descriptor
when using the TX/RX dumping capabilities in debugfs.

This patch (based on Ron Rindjunsky's) creates a framework for
a unified way to pass BSS configuration to drivers that require
the information, e.g. for implementing power save mode.
This patch introduces new ieee80211_bss_conf structure that is
passed to the driver via the new bss_info_changed() callback
when the BSS configuration changes.
This new BSS configuration infrastructure adds the following
new features:
* drivers are notified of their association AID
* drivers are notified of association status
and replaces the erp_ie_changed() callback. The patch also does
the relevant driver updates for the latter change.

This patch fixes an oops which was introduced as a regression by
commit fd640775bd16e1df50c867cc547af0, on the patch titled,
"mac80211: dont use interface indices in drivers".
ieee80211_generic_frame_duration() now relies on sdata->flags which
itself gets set upon bringing the interface up. We check for the
virtual interface now before setting the rate duration registers.
After the mode changes are introduced onto mac80211 we should revisit
these changes.

This patch gets rid of the if_id stuff where possible in favour of
a new per-virtual-interface structure "struct ieee80211_vif". This
structure is located at the end of the per-interface structure and
contains a variable length driver-use data area.
This has two advantages:
* removes the need to look up interfaces by if_id, this is better
for working with network namespaces and performance
* allows drivers to store and retrieve per-interface data without
having to allocate own lists/hash tables
