This flag is protected by the + * spinlock. All code which touches the hardware should check the + * flag after taking the lock, and if it is set, give up on whatever + * they are doing and drop the lock again.

This flag is protected by the - * spinlock. All code which touches the hardware should check the - * flag after taking the lock, and if it is set, give up on whatever - * they are doing and drop the lock again. The orinoco_lock() - * function handles this (it unlocks and returns -EBUSY if - * hw_unavailable is non-zero). - */ - -#define DRIVER_NAME "orinoco" - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include - -#include "hermes_rid.h" -#include "hermes_dld.h" -#include "orinoco.h" - -/********************************************************************/ -/* Module information */ -/********************************************************************/ - -MODULE_AUTHOR("Pavel Roskin & " - "David Gibson "); -MODULE_DESCRIPTION("Driver for Lucent Orinoco, Prism II based " - "and similar wireless cards"); -MODULE_LICENSE("Dual MPL/GPL"); - -/* Level of debugging.

This issue happens only when we are associated with a 11n AP and power save is enabled. In the function 'ieee80211_master_start_xmit', ps_disable_work is queued where wake_queues is called. But before this work is executed, we check if the queues are stopped in _ieee80211_tx and return TX_AGAIN to ieee8011_tx which leads to the warning message. This patch fixes this erroneous case.

This was added to support ath9k. But this is a bit controversial because the AP will send multicast frames immediately after the beacon and the time constraints are really high. Relying mac80211 to be fast enough here might not be reliable in all situations. And there's no need to send a null frame, AP will send the frames immediately after the dtim beacon no matter what. Also if dynamic power save is disabled (iwconfig wlan0 power timeout 0) currently mac80211 disables power save whenever the multicast bit is set but it's never enabled again after receiving the first multicast/broadcast frame. The current implementation is not usable on p54/stlc45xx and the easiest way to fix this is to remove the multicast tim bit check altogether. Handling multicast tim bit in host is rare, most of the designs do this in firmware/hardware, so it's better not to have it in mac80211. It's a lot better to do this in firmware/hardware, or if that's not possible it could be done in the driver. Also renamed the function to ieee80211_check_tim() to follow the style of the file.

But if dynamic power save is disabled, mac80211 will not enable power save ever gain. Fix this by adding ps-poll functionality to mac80211. When a directed tim bit is set, mac80211 sends a ps-poll frame to the AP and checks for the more data bit in the returned data frames. Using ps-poll is slower than waking up with null frame, but it's saves more power in cases where the traffic is low. Userspace can control if either ps-poll or null wakeup method is used by enabling and disabling dynamic power save. Signed-off-by: Kalle Valo Signed-off-by: John W.

Additionally, the TX agg code seems to leak memory when TX aggregation is not disabled before the sta_info is freed. Fix this by making the free code a little smarter in the RX agg case, and actually make the sta_info_destroy code free the TX agg info in the TX agg case. We won't notify the peer, but it'll notice something is wrong anyway, and normally this only happens after we've told it in some other way we will no longer talk to it.
