| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | iwlagn: implement WoWLANJohannes Berg2011-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | iwlagn: rewrite HW cryptoJohannes Berg2011-07-21

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.
