2012-02-15wl12xx: add support for HW dynamic PSEyal Shapira1-8/+0
FW now supports dynamic PS so we don't need to use mac80211 support. FW will go to PSM after a specified timeout with no Rx/Tx traffic. - Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter - The default PS mode would be dynamic PS - Default timeout is 100ms (same as it used to be in mac80211) - Avoid using mac80211 APIs to disable/enable dynamic PS as we're not using mac80211 PS control anymore. - COEX is handled by the FW while in dynamic PS so removed handling of SOFT_GEMINI Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-02-15wl12xx: remove unnecessary shadow declarationLuciano Coelho1-1/+2
The vif variable was being declared inside one of the internal blocks of wl1271_event_process. This is not necessary, since this variable is already declared in the function context. Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-12-20wl12xx: mark no sched scan only after FW eventEyal Shapira1-1/+1
stop sched scan isn't an immediate operation and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID after sending a stop before changing internal state and notifying upper layers. Not doing this caused problems when canceling an existing sched scan and immediately requesting to start a new one with a different configuration as the FW was still in the middle of the previous sched scan.

2011-11-08wl12xx: keep beacon-filtering enabled during STA operationArik Nemtsov1-5/+0

2011-10-11wl12xx: move debugging definitions to a separate fileLuciano Coelho1-0/+1
Separate the debugging macros and other definitions to a new debug.h file. This is be needed because the sdio and spi modules don't need to depend on the wl12xx module anymore, but still need to include wl12xx.h. Currently they do depend on it, because of the debugging global that wl12xx exports. A future patch will remove this dependency. Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: add band field to wlvifEliad Peller1-1/+1
add band field into the per-interface data. mac80211 configures some values (e.g. band, channel) globally, while we configure them per-interface. In order to make it easier to keep track of the configured value for each value while keeping sync with mac80211, save these values both globally and per-vif.

2011-10-11wl12xx: rearm rx streaming per vifEliad Peller1-2/+2
Currently, the rx streaming doesn't support multi-vif (the actual wlvif is taken from wl->vif, and the management is global).

2011-10-11wl12xx: make event handling support multiroleEliad Peller1-40/+81

2011-10-07wl12xx: replace wl->mac_addr with vif->addrEliad Peller1-1/+1
The mac address of the interface already exists in vif->addr. Use it instead of wl->mac_addr. It seems that due to some fw bug, we still need to set nvs->mac to the actual mac addresss, otherwise the fw doesn't function well (e.g. can't get dhcp address). Thus, use wl->mac_addr for this purpose, and don't delete it yet. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-07wl12xx: Add support for HW channel switchShahar Levi1-0/+15

2011-08-22wl12xx: update commands & eventsEliad Peller1-2/+2
Change the commands and events according to the new fw api (fw >= 6/7.3.0.0.75). The main change is the replacement of JOIN/DISCONNECT commands, with ROLE_START/ROLE_STOP commands. The use of these commands should be preceded by the ROLE_ENABLE command (allocating role resources), and followed by the ROLE_DISABLE command (freeing role resources).

2011-04-28wl12xx: support FW TX inactivity triggersArik Nemtsov1-0/+47
In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events. Both are reported to the upper layers as a TX failure in the offending stations. In STA mode we register only for the MAX_TX_RETRY event. A TX failure is interpreted as a loss of connection. Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid the inherent race condition of a mac80211 TX failure counter in addition to the FW counter.

2011-04-19wl12xx: rearrange some ELP wake_up/sleep callsEliad Peller1-5/+6
ELP (Extremely/Enhanced Low Power, or something like that ;)) refers to the powerstate of the 12xx chip, in which very low power is consumed, and no commands (from the host) can be issued until the chip is woken up. Wakeup/sleep commands must be protected by a wl->mutex, so it's generally a good idea to call wakeup/sleep along with the mutex lock/unlock (where needed). However, in some places the wl12xx driver calls wakeup/sleep in some "inner" functions. This result in some "nested" wakeup/sleep calls which might end up letting the chip go to sleep prematurely (e.g. during event handling). Fix it by rearranging the elp calls to come along with mutex_lock/unlock.

Support sending dummy packet to wl128x FW as results of dummy packet event. That is part of dynamic TX mem blocks mechanism. Only send dummy packet when not in AP mode. [Even though the DUMMY_PACKET_EVENT_ID and the STA_REMOVE_COMPLETE_EVENT_ID events are defined to the same value, we need to treat them separately in the code. Keep the check and enable STA_REMOVE_COMPLETE_EVENT_ID for AP mode and DUMMY_PACKET_EVENT_ID for STA. Moved one warning to a cleaner place.
