    mac80211: document ieee80211_rx() context requirement · d20ef63d
    Johannes Berg authored
    ieee80211_rx() must be called with softirqs disabled
    since the networking stack requires this for netif_rx()
    and some code in mac80211 can assume that it can not
    be processing its own tasklet and this call at the same
    It may be possible to remove this requirement after a
    careful audit of mac80211 and doing any needed locking
    improvements in it along with disabling softirqs around
    netif_rx(). An alternative might be to push all packet
    processing to process context in mac80211, instead of
    to the tasklet, and add other synchronisation.
