Here is v5 of my dynamic powersave patches. I have tested them with
stlc45xx on Nokia N810.
I think (and hope) that the patches are close to inclusion now. Please
review.
changes in v6:
o use IEEE80211_CONF_CHANGE_PS in ieee80211_set_disassoc()
changes in v5:
o check STA interface earlier in siwpower()
o moved queue track patch before dynamic power save patch
o add new functions ieee80211_wake_queues_by_reason() and
ieee80211_stop_queues_by_reason() for optimised locking
o dropped "move dynamic_ps_timeout to hw.conf" for now, will resubmit
it later when I have example driver implementation
o renamed the hw flag to IEEE80211_HW_NO_STACK_DYNAMIC_PS and inverted
it's functionality, now drivers need to explicitly disable the feature
o folded hw flag patch to the main dynamic power save patch
changes in v4:
o add check for station interface to siwpower()
o call hw_config() also for dynamic timeout changes
o add dynamic_ prefix to workqueues
o test for IEEE80211_HW_NO_DYNAMIC_PS in siwpower()
o wrote documentation for IEEE80211_HW_NO_DYNAMIC_PS
o wrote documentation for conf->dynamic_ps_timeout
changes in v3:
o add a hw flag to notify that driver doesn't support dynamic power save and
which will enable mac80211 implementation
o delete dynamic_ps_timer and cancel ps_enable_work during
association, hopefully it's race free now
o provide timeout value to the drivers, for example iwlwifi should use
it (example patch under works)
o fix a bad bug in testing IEEE80211_STA_ASSOCIATED flag with && operator
Power save related features which I'll implement later:
o disable power save when software scanning
o move dynamic_ps_timeout to hw.conf so that drivers can use it in
case they need to
o beacon period (wakeup period) to the drivers, can be set from user
space but otherwise is bss's DTIM value
