For 105/135 series of devices, we need to do I/Q invert just like 2000

Implement WoWLAN support in iwlagn. The device
supports a number of wakeup triggers and can do
GTK rekeying when asleep (if HW crypto is used).
Unfortunately, we need to disconnect from the AP
after resume since we can't yet get all the info
out of the wowlan uCode to stay connected safely.

As I just discovered while doing WoWLAN, HW crypto
is done wrong for GTKs: they should be programmed
for the AP station ID (in the managed mode case)
and the HW can actually deal with multiple group
keys per station as well (which is useful in IBSS
RSN but that I've chosen not to use this).

To fix all this, modify the way keys are sent to
the device and key offsets are allocated. After
these changes, key offsets are stored into the
hw_key_idx which we can then track for the key
lifetime, not relying on our sta_cmd array. WEP
default keys get special treatment, of course.

Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.

Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

WoWLAN may need the NIC even after suspend. One should not do anything to the

The price to pay is the access to the log system. Therefore logs from bus layer

Call iwl_probe with a ready iwl_bus struct. This means that the bus layer
assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to
iwl_probe.

The device specific struct is allocated together with the common iwl_bus struct
by the bus specific layer. The pointer to the aggregate struct is passed to the
upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus.
The private data given to the PCI subsystem is now iwl_bus and not iwl_priv.

Provide bus_* inliners on the way in order  to simplify the syntax.

Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the
external of the bus layer.

In P2P client mode, the GO (AP) to connect to might
have periods of time where it is not available due
to powersave. To allow the driver to sync with it
and send frames to the GO only when it is available
add a new callback tx_sync (and the corresponding
finish_tx_sync). These callbacks can sleep unlike

Both ath5k_hw and ath5k_softc represent one instance of the hardware.
This duplication is historical and is not needed anymore.

Keep the name "ath5k_hw" for the merged structure and "ah" for the
variable pointing to it.  "ath5k_hw" is shorter than "ath5k_softc", more
descriptive and more widely used.

Put the combined structure to ath5k.h where the old ath5k_softc used to
be. Move some code from base.h to ath5k.h as needed.

Remove memory allocation for struct ath5k_hw and the corresponding error
handling.  Merge iobase and ah_iobase fields.
