    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.
