* wl12xx: check the actual vif operstate in wl1271_dev_notifyEliad Peller2011-12-20
| | | | | | | | | | | | The current wl1271_dev_notify implementation sets the new operstate to all associated stations (while only a specific vif was changed). Until we'll have a method to get the actual vif from the given dev, check the current operstate of each vif.

* wl12xx: stop device role on remove_interfaceEliad Peller2011-12-20
| | | | | | | | When removing a sta/ibss role, the device role has to stopped (and disabled) as well. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: fix checking of started dev roleEliad Peller2011-12-20
| | | | | | | | | | | | | | | dev_role_id only indicates whether the dev role is enabled, not started (e.g. on IBSS merge, the device role is enabled, but not started). Checking for any role in ROC (in order to determine whether dev role was started) is wrong as well, especially in multi-vif env. Check for started dev role only by checking the dev_hlid.

* wl12xx: make WL1271_FLAG_IDLE flag per-vifEliad Peller2011-12-20
| | | | | | | | | | | | | This flag should be set per-vif, rather than globally. Rename the flag to indicate IN_USE (rather than IDLE), as in the default configuration (i.e. flag is clear) the vif should be idle. Change all the bit operations (and elp conditions) appropriately.

* wl12xx: remove redundant code from wl1271_op_conf_txEliad Peller2011-12-20
| | | | | | | | | | Since the conf_tx callback passes the vif as param, we must have been added first (and mac80211 verifies it). Remove the handling of such case. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

* wl12xx: avoid bail out when probe-resp is not set by mac80211Arik Nemtsov2011-12-01
| | | | | | | | | | | | | | During reconfig we can get the BSS_CHANGED_AP_PROBE_RESP indication even if a probe-resp has not been set in the first place. Therefore ignore the error when not getting a probe-resp from mac80211. Resort to the legacy probe-resp in this case. Also take this opportunity to add a vif argument to the set_probe_resp function.

* wl12xx: use the same SDIO block size for all different chipsLuciano Coelho2011-11-08
| | | | | | | | | | | | | | | | | The sdio driver uses a block size of 512 bytes by default. With our card, this doesn't work correctly because it sets the block size FBR in the chip too early (ie. before the chip is powered on). Thus, if we don't set it explicitly, block mode remains disabled in the chip. If we try to send more data than fits in one block, the sdio driver will split it into separate blocks before sending to the chip. This causes problems because the chip is not expecting multiple blocks. At the moment this is not a problem, because we use chunks of 512 bytes for firmware upload and the data is always sent in byte mode. In the next patch, we will change the chunk size to a bigger value, so this patch is a preparation for that. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: change blocksize alignment quirk to negativeLuciano Coelho2011-11-08
| | | | | | | | | SDIO blocksize alignment support is now the rule, not the exception. To simplify the code in patches to come, invert the meaning of the quirk to be negative (ie. the quirk is set if the device does _not_ support blocksize alignment). Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: clear wl->vif on remove_interfaceEliad Peller2011-11-08
| | | | | | | | | | | wl->vif should be cleared on remove_interface() (rather than on stop()) even when only a single vif is supported, because during vif mode change stop() might not get called (e.g. because of monitor interface existence) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: reconfigure rate policies on set_bitrate_maskEliad Peller2011-11-08

* wl12xx: couple role_start_dev with rocEliad Peller2011-11-08
| | | | | | | | | | | | | Device role is always started along with ROC. Couple them together by introducing new wl12xx_start_dev and wl12xx_stop_dev functions. By using these functions, we solve a bug that occured during channel switch - we started the dev role on one channel, and ROCed on a different one.

* wl12xx: handle injected packetsEliad Peller2011-10-11
| | | | | | | | | | | | | | | Injected packets are sent with no vif, causing the wl12xx to NULL-dereference in multiple places. Furthermore, injected packets are currently not sent at all, as system_hlid doesn't belong to any specific role, so wl1271_skb_dequeue() never return its packets. Handle both these problems.

* wl12xx: use the same plat dev name for both SPI and SDIOLuciano Coelho2011-10-11
| | | | | | | | | | | | | | There's no need to have the bus name included in the platform device name that we create. The core driver doesn't need to know about the type of bus it uses. Any differences between the buses that need to be handled differently in the core, can be passed in the platform data (as the pwr_in_suspend boolean does). Use "wl12xx" for the device name in both bus drivers. Rename the platform driver name to "wl12xx_driver", just to differentiate from the platform device names.

* wl12xx: move debugging definitions to a separate fileLuciano Coelho2011-10-11
| | | | | | | | | | | 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>
