      mac80211: push rx status into skb->cb · f1d58c25
      Johannes Berg authored
      
      
      Within mac80211, we often need to copy the rx status into
      skb->cb. This is wasteful, as drivers could be building it
      in there to start with. This patch changes the API so that
      drivers are expected to pass the RX status in skb->cb, now
      accessible as IEEE80211_SKB_RXCB(skb). It also updates all
      drivers to pass the rx status in there, but only by making
      them memcpy() it into place before the call to the receive
      function (ieee80211_rx(_irqsafe)). Each driver can now be
      optimised on its own schedule.

      mac80211: cancel/restart all timers across suspend/resume · 5bb644a0
      Johannes Berg authored
      
      
      We forgot to cancel all timers in mac80211 when suspending.
      In particular we forgot to deal with some things that can
      cause hardware reconfiguration -- while it is down.
      
      While at it we go ahead and add a warning in ieee80211_sta_work()
      if its run while the suspend->resume cycle is in effect. This
      should not happen and if it does it would indicate there is
      a bug lurking in either mac80211 or mac80211 drivers.
      
      With this now wpa_supplicant doesn't blink when I go to suspend
      and resume where as before there where issues with some timers
      running during the suspend->resume cycle. This caused a lot of
      incorrect assumptions and would at times bring back the device
      in an incoherent, but mostly recoverable, state.
