2011-08-01rtlwifi: Fix kernel oops on ARM SOCLarry Finger1-9/+11
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.

2011-08-01ath9k: skip ->config_pci_powersave() if PCIe port has ASPM disabledStanislaw Gruszka5-13/+40
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. Bug was introduced by: commit 53bc7aa08b48e5cd745f986731cc7dc24eef2a9f Author: Vivek Natarajan <[email protected]> Date: Mon Apr 5 14:48:04 2010 +0530 ath9k: Add support for newer AR9285 chipsets.

2011-07-21mwifiex: put multicast/broadcast packets to the same RAAmitkumar Karwar1-0/+2
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.

2011-07-21iwlagn: track beacon interval sent to deviceJohannes Berg3-6/+9
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.

2011-07-21iwlagn: implement WoWLANJohannes Berg11-14/+705
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.

2011-07-21iwlagn: rewrite HW cryptoJohannes Berg6-224/+200
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.

2011-07-21iwlagn: simplify the bus architectureEmmanuel Grumbach14-140/+161
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.
