We've fixed the last issue with BCMA support which caused memory
corruption on loading and unloading b43. Support for BCMA in b43 was
tested with 14e4:4353, 14e4:4357, 14e4:4727 and 14e4:4331. First two
cards (BCM43224 and BCM43225) are supported.

At the beginning of wiphy_update_regulatory() a check is performed
whether the request is to be ignored. Then the request is sent to
the driver nevertheless. This happens even if last_request points
to NULL, leading to a crash in the driver:

Some devices (e.g. Ubiquiti AirRouter) ship with broken EEPROM chainmask
data, which breaks the initial calibration after a hardware reset.
To fix this, mask the eeprom chainmask with the chainmask of the chip,

For ad-hoc mode, RA is created for each peer connected. In case of
multicast traffic new RA will be created for each multicast
address. While processing Tx packets we have to go through this
RA list. We can avoid some RA nodes by sharing same RA for both
multicast and broadcast packets.

Therefore "memset(0xff)" is used to treat multicast packet as broadcast
one while choosing RA.

Sometimes, when mac80211 changes the beacon
interval or when it isn't yet set in mac80211
before association, the uCode will sysassert
because we send it confusing RXON timing vs.
PAN parameters. To fix this, track the last
beacon interval sent to the device and use
that in PAN parameter calculations.

This fixes a bug during P2P group formation
as a client (and possibly association to a
regular AP) while connected to another AP.

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.

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.
