SYNOPSIS

       void ieee80211_unregister_hw(struct ieee80211_hw * hw);

ARGUMENTS

       hw
	   the hardware to unregister

NAME

       enum_ieee80211_filter_flags - hardware filter flags

SYNOPSIS

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

CONSTANTS

       FIF_PROMISC_IN_BSS
	   promiscuous mode within your BSS, think of the BSS as your network segment and then this corresponds to the regular ethernet device
	   promiscuous mode.

       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), if PROMISC_IN_BSS is not set then only those addressed to this station.

       FIF_OTHER_BSS
	   pass frames destined to other BSSes

       FIF_PSPOLL
	   pass PS Poll frames, if PROMISC_IN_BSS is not set then only those addressed to this station.

       FIF_PROBE_REQ
	   pass probe request frames

HW QUEUE CONTROL

       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.
