2011-09-14libertas: prioritize usb8388_olpc.bin firmware on OLPC machinesAndres Salomon1-0/+21
Normally, the v9 firmware will be loaded if it's available. However, on OLPC XO-1 machines, the olpc-specific firmware supports extra functionality. This makes the libertas driver attempt to load the custom firmware first if the machine is an OLPC machine; if that fails (or it's not an OLPC machine), fall back to attempting to load the other firmwares. usb8388_olpc.bin is currently found in the linux-firmware repository.

2011-09-14rt2x00: Forbid aggregation for STAs not programmed into the hwHelmut Schaa1-0/+11
If a STA is not known by the hw (i.e. has no WCID assigned) don't allow aggregation since this might mess up tx status reports and we won't be able to distinguish the reports of multiple WCID-less STAs.

2011-09-14rt2x00: Make use of sta_add/remove callbacks in rt2800Helmut Schaa4-30/+134
This allows us to assign a WCID to each STA even for STAs without crypto key. To achieve this search for an unused WCID in the HW WCID table and assign it to the according STA. When configuring a pairwise key for this STA we don't need to write the MAC address and BSSIDX anymore but just update the crypto related fields in the WCID_ATTR table. This has two advantages: 1) Setting a new key for an already available STA (PTK rekeying) is slightly less expensive and should improve performance in situations where a lot of rekeying happens (e.g. a huge number of stations and/or a small rekeying interval) 2) The TXWI now gets a WCID assigned for unencrypted frames which will be reflected in the corresponding tx status report. This should make tx status reports in unencrypted AP mode more reliable as we can distinguish between multiple key-less STAs.

2011-09-14rt2x00: Add WCID to HT TX descriptorHelmut Schaa2-1/+7
When sending an unencrypted frame to a STA the driver might want to pass a suitable WCID since we don't have a key index to allow tx status reports to get properly assigned to the correct STA.

2011-09-14rt2x00: Add WCID to crypto structHelmut Schaa2-2/+7
When a WCID was already assigned to a STA the key configuration functions need to use the same WCID for configuring the keys. Hence, add the WCID to the crypo configuration structure.

2011-09-14rt2x00: Introduce sta_add/remove callbacksHelmut Schaa3-0/+60
This implements a basic sta_add and sta_remove callback. Introduce a new structure rt2x00_sta and ask mac80211 to allocate it as private part of its ieee80211_sta. rt2x00_sta only contains the WCID for now. The sta_add callback allows the driver to assign a WCID to a station that is currently being added. The same wcid is also passed to the sta_remove callback one mac80211 removes this STA.

2011-09-14mac80211: Update device channel in case of HW channel switch supportedShahar Levi1-0/+3
The hw.conf.channel value is not updated properly for drivers that support HW channel switch. Since the switch is done entirely by the driver and we don't call ieee80211_hw_config(), this value remains untouched.

2011-09-14mac80211: Start implementing QoS support for mesh interfacesJavier Cardona4-10/+14
In order to support QoS in mesh, we need to assign queue mapping only after the next hop has been resolved, both for forwarded and locally originated frames. Also, now that this is fixed, remove the XXX comment in ieee80211_select_queue(). Also, V-Shy Ho reported that the queue mapping was not being applied to the forwarded frame (fwd_skb instead of skb).

rt2800 devices are not capable of configuring arbitrary LED on/off periods. The LED_CFG register fields ON_PERIOD and OFF_PERIOD are only used by the hw when the LED mode is set to "blink upon TX".
