This can cause errors since the unlinking code can't currently deal with items that have already been unlinked. Normally this doesn't happen as most people don't try to use multiple station interfaces that associate at the same time too. Fix this by using the list entry as a flag to see if the item is still on a list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 7acc7c683a747689aaaaad4fce1683fc3f85e552. It was applied to avoid possible warning in ieee80211_restart_hw, however reason of the warning were races in mac80211, currently hopefully fixed. Not reseting device when performing scan is bad for two reasons. When forcing reset from iwl_check_stuck_queue(), in case of fail, reset will be repeated until scan finish. But since firmware is in bad shape, scan only finish after scan_check work (about 7s). So we will delay the reset, what is not good behaviour. When forcing reset from iwl_recover_from_statistics(), we will not repeat the reset, so we will not perform reset at all when needed.

We do not canceling such requests when calling ieee80211_scan_cancel(), because of SCAN_SW_SCANNING bit check just before the call. So fix that problem. Another problem, which commit 85f72bc839705294b32b6c16b491c0422f0a71b3 tries to solve, is we can not cancel HW scan. Hence patch make ieee80211_scan_cancel() ignore HW scan (see code comments).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We never delete the addBA response timer, which is typically fine, but if the station it belongs to is deleted very quickly after starting the BA session, before the peer had a chance to reply, the timer may fire after the station struct has been freed already. Therefore, we need to delete the timer in a suitable spot -- best when the session is being stopped (which will happen even then) in which case the delete will be a no-op most of the time.

| * | wl1271: Move work-init calls to hw allocationJuuso Oikarinen2010-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to legacy reason, dating back to when the wl1251 and wl1271 still were a unified driver, some work-structures are initialized on hardware startup. The hardware recovery code creates a scenario in which it is possible for a workstruct to be re-initialized while the work-function itself is running, which causes a kernel WARNing and a subsequent reboot. To remedy this, move the work initialization calls to the hw allocation, which is the logically correct place for them anyway.
