rtlwifi: Fix kernel oops on ARM SOC
This driver uses information from the self member of the pci_bus struct to
get information regarding the bridge to which the PCIe device is attached.
Unfortunately, this member is not established on all architectures, which
leads to a kernel oops.
Skipping the entire block that uses the self member to determine the bridge
vendor will only affect RTL8192DE devices as that driver sets the ASPM support
flag differently when the bridge vendor is Intel. If the self member is
available, there is no functional change.
This patch fixes Bugzilla No. 40212.

ath9k: skip ->config_pci_powersave() if PCIe port has ASPM disabled
We receive many bug reports about system hang during suspend/resume
when ath9k driver is in use. Adrian Chadd remarked that this problem
happens on systems that have ASPM disabled.
To do not hit the bug, skip doing ->config_pci_powersave magic if PCIe
downstream port device, which ath9k device is connected to, has ASPM
disabled.
Patch should address:
https://bugzilla.kernel.org/show_bug.cgi?id=37462
https://bugzilla.kernel.org/show_bug.cgi?id=37082
https://bugzilla.redhat.com/show_bug.cgi?id=697157
however I did not receive confirmation about that, except from Camilo
Mesias, whose system stops hang regularly with this patch (but still
hangs from time to time, but this is probably some other bug).

iwlagn: rewrite HW crypto
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.

The device specific struct is allocated together with the common iwl_bus struct

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.
