Subject: [PATCH v2 0/8] wl12xx: AP-mode per link PSM
Date: Wed, 23 Feb 2011 00:22:23 +0200 [thread overview]
Message-ID: <1298413351-15462-1-git-send-email-arik@wizery.com> (raw)
This patchset introduces per-link PSM for AP-mode. The PS status of each
link is updated from FW.
The wl12xx concept of PSM is different from the mac80211 one - some data
must remain in FW for a link in PSM since the TIM is updated automatically
by FW. This functionality depends on the following mac80211 patch:
"mac80211: add HW flag for disabling auto link-PS in AP mode"
We set up a skb-queue per link which allows for a cleaner link
disconnection and prepares the code for regulating each link separately.
A few other AP-mode related small bug fixes and enchancements are included.
v1->2:
- In first patch, use atomic operations when changing the flags
variable. It is not always changed within a spinlock/mutex.
- Rebase on latest master of maintainer's git
