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.
