* ath9k: make beacon timer initialization more reliableFelix Fietkau2011-09-16
| | | | | | | | | When starting the AP beacon timer, it assumes that the TSF has recently been cleared. Set the SC_OP_TSF_RESET flag to ensure that this is always the case. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: fix enabling interrupts after a hardware error interruptFelix Fietkau2011-09-16

| | | | | | | | | | | | | | | | | | | | | | | | When we are scanning for the wildcard SSID in a scheduled scan, we should use SCAN_SSID_TYPE_PUBLIC so that we don't filter out the scan results. Signed-off-by: Luciano Coelho <coelho@ti.com>
| | * wl12xx: add support for multiple SSIDs in sched_scanLuciano Coelho2011-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wl12xx firmwares support multiple SSIDs in a single sched_scan run. This patch implements support for it. We use three different types os sched_scan: FILTER_ANY (ie. not filtering, only wildcard SSID in the probe_reqs); FILTER_LIST (ie. send out probe_reqs with the specified SSIDs and only report if they are found); and FILTER_DISABLED (ie. send out probe_reqs with the specified SSIDs, but report anything found). Since we still don't have proper filter support in nl80211/cfg80211 yet, we cannot use filters when the wildcard SSID is used. Thus, we will not filter anything if the wildcard SSID is specified.

* | | libertas: prioritize usb8388_olpc.bin firmware on OLPC machinesAndres Salomon2011-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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