* atheros: introduce ath module containing common ath5k/ath9k/ar9170 codeBob Copeland2009-04-22
| | | | | | | | | | This change creates a new module, ath.ko, which includes code that can be shared between ath5k, ath9k and ar9170. For now, extract most of the ath9k regulatory code so it can also be used in ath5k. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Luis R.

* ath9k: pass regd structure directly to regulatory functionsBob Copeland2009-04-22
| | | | | | | | | | | | All regulatory information is encapsulated by the ath9k_regulatory struct, so we can now change all the callers to take that directly instead of struct ath_hw. This in turn will enable us to move the regulatory functions to common code also used by ath5k, since both can use this regulatory struct.

* ath9k: separate ath9k specific code from ath9k_regd_get_ctl()Bob Copeland2009-04-22
| | | | | | | | | | | Until ath5k and ath9k share common channel structures, they will have to implement their own get_ctl() function. Split out the portion that only relies on the current band and reg domain so that it can be common code. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Luis R.

* iwlwifi: change check triggering device restart after rfkill changeReinette Chatre2009-04-22
| | | | | | | | | | | | | | | | | The STATUS_ALIVE value cannot be used because it is cleared when interface is brought down and will not be set if rfkill is enabled when interface is started again. The interface can thus not be brought up if rfkill was enabled before stopping the interface and disabled after starting the interface. Change the test to use priv->is_open instead, this will be set when interface is started whether rfkill is enabled or not. Thanks to Helmut Schaa for the suggested fix.

* p54: more SoftLED updatesChristian Lamparter2009-04-22
| | | | | | | | | | | | | | | This patch hopefully finishes the SoftLED code: - It adds two more LEDs (rx and radio). (the FW claims it can support up to 16 LEDs, but I doubt that any vendor put more than 4 on a board) - update the LEDs in a _delayed_ workqueue. No one reported any more crashes. (see: "PATCH] p54: fix race condition in memory management") So we can stop burning the mm code.

* ath5k: reduce exported channel listBob Copeland2009-04-22
| | | | | | | | | | | | | | | | | | | | | | Claiming every available 5 ghz channel has a couple of negative side-effects: scanning takes a long time, and the channel list overflows the available buffer space for netlink commands, resulting in: $ iw phy phy0 info command failed: No buffer space available (-105) This patch adds a modparam so people who want to see all the channels can do so by passing all_channels=1. By default users will see a smaller list of channels. This also halves scan time, from 10 seconds down to less than 5 when using world regulatory.
