74a3a2509d iwlwifi: cleanup usage of inline functions
Be consistent when using inline functions. If the function only used
once we move it to where it is used - no need for externs.

5a66926aa9 iwlwifi: delay firmware loading from pci_probe to network interface open
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.

471b3efdfc mac80211: add unified BSS configuration
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.

12342c475f iwlwifi: proper monitor support
This patch changes the iwlwifi driver to properly support
monitor interfaces after the filter flags change.

The patch is originally created by Johannes Berg for iwl4965. I fixed some
of the comments and created a similar patch for iwl3945.

This patch give the iwlwifi the ability to support A-MSDU up to 8K

Please notice - in order to work in 8K A-MSDU ucode support is needed,
version 4.44.1.19 (soon to be published). 4K A-MSDU works in current ucode
version as well.

5d08cd1dfd iwlwifi: keep 3945 and 4965 headers separate
The iwl3945 and iwl4965 devices share some common structure, but with a
lot of difference split all over.  Currently the two drivers share a lot
of headers and use ugly preprocessor magic to manage the difference.

This patch keeps two entirely separate copies of the headers to get rid
of these hacks an ease future development.
