    mac80211: allow out-of-band EOSP notification · 37fbd908
    Johannes Berg authored
    iwlwifi has a separate EOSP notification from
    the device, and to make use of that properly
    it needs to be passed to mac80211. To be able
    to mix with tx_status_irqsafe and rx_irqsafe
    it also needs to be an "_irqsafe" version in
    the sense that it goes through the tasklet,
    the actual flag clearing would be IRQ-safe
    but doing it directly would cause reordering
    issues.
    
    This is needed in the case of a P2P GO going
    into an absence period without transmitting
    any frames that should be driver-released as
    in this case there's no other way to inform
    mac80211 that the service period ended. Note
    that for drivers that don't use the _irqsafe
    functions another version of this function
    will be required.
