This driver uses the core orinoco modules for the bulk of
the functionality. The low level hermes routines (for local bus
cards) are replaced, the driver supplies its own ndo_xmit_start
function, and locking is done with the _bh variant.
Some recent functionality is not available to the USB cards yet
(firmware loading and WPA).
Out-of-tree driver originally written by Manuel Estrada Sainz.
Thanks to Mark Davis for supplying hardware to test the updates.

Local bus and USB drivers will need to do locking differently.
The original orinoco_usb patches had a boolean variable controlling
whether spin_lock_bh was used, or irq based locking. This version
provides wrappers for the lock functions and the drivers specify the
functions pointers needed.
This will introduce a performance penalty, but I'm not expecting it to
be noticable.

Allow the main drivers to specify a custom version of the net_device_ops
structure. This is required by orinoco_usb to supply a separate transmit
function.
Export existing net_device_ops callbacks so that the drivers can reuse
some of the existing code.

When TKIP support was added, we stored the keys separately to avoid
issues when both TKIP and WEP keys are sent to the driver.
We need to consolidate the storage to convert to cfg80211, so do this
first and try iron out the issues.

This removes the custom scan cache used by orinoco.
We also have to avoid calling cfg80211_scan_done from the hard
interrupt, so we offload the entirety of scan processing to a workqueue.
This may behave strangely if you start scanning just prior to
suspending...

Each device does almost exactly the same things on suspend and resume
when upping and downing the interface. So move this logic into a common

With the move to cfg80211 it's nice to keep the hardware operations
distinct from the interface, even though we can only support a single
interface.
This also means the driver resembles other cfg80211 drivers.

Initialise and register a wiphy.
Store the orinoco_private structure in the new wiphy, and use the
net_device private area to store the wireless_dev. This results in a
change to the way we navigate from a net_device to the driver private
orinoco_private, which we encapsulate in the inline function ndev_priv.
Most of the remaining calls to netdev_priv are thus replaced by
ndev_priv.
We can immediately rely on cfg80211 to handle SIOCGIWNAME, so
orinoco_ioctl_getname is removed.

Move away from using net_device as the main structure in orinoco
function calls. Use orinoco_private instead.
This makes more sense when we move to cfg80211, and we get wiphys as
well.

Make firmware caching on startup optional, and make it default.
When the option is not selected and PM_SLEEP is configured, then
cache firmware in the suspend pm_notifier. This configuration saves
about 64k RAM in normal use, but can lead to a situation where the
driver is configured to use a different firmware.
