ENUM IEEE80211_FILTE(9)           The basic mac80211 driver inte          ENUM IEEE80211_FILTE(9)



NAME
       enum_ieee80211_filter_flags - hardware filter flags

SYNOPSIS
       enum ieee80211_filter_flags {
         FIF_ALLMULTI,
         FIF_FCSFAIL,
         FIF_PLCPFAIL,
         FIF_BCN_PRBRESP_PROMISC,
         FIF_CONTROL,
         FIF_OTHER_BSS,
         FIF_PSPOLL,
         FIF_PROBE_REQ
       };

CONSTANTS
       FIF_ALLMULTI
           pass all multicast frames, this is used if requested by the user or if the hardware is
           not capable of filtering by multicast address.

       FIF_FCSFAIL
           pass frames with failed FCS (but you need to set the RX_FLAG_FAILED_FCS_CRC for them)

       FIF_PLCPFAIL
           pass frames with failed PLCP CRC (but you need to set the RX_FLAG_FAILED_PLCP_CRC for
           them

       FIF_BCN_PRBRESP_PROMISC
           This flag is set during scanning to indicate to the hardware that it should not filter
           beacons or probe responses by BSSID. Filtering them can greatly reduce the amount of
           processing mac80211 needs to do and the amount of CPU wakeups, so you should honour
           this flag if possible.

       FIF_CONTROL
           pass control frames (except for PS Poll) addressed to this station

       FIF_OTHER_BSS
           pass frames destined to other BSSes

       FIF_PSPOLL
           pass PS Poll frames

       FIF_PROBE_REQ
           pass probe request frames

DESCRIPTION
       These flags determine what the filter in hardware should be programmed to let through and
       what should not be passed to the stack. It is always safe to pass more frames than
       requested, but this has negative impact on power consumption.
