CONSTANTS

21       FIF_PROMISC_IN_BSS
22           promiscuous mode within your BSS, think of the BSS as your network
23           segment and then this corresponds to the regular ethernet device
24           promiscuous mode.
25
26       FIF_ALLMULTI
27           pass all multicast frames, this is used if requested by the user or
28           if the hardware is not capable of filtering by multicast address.
29
30       FIF_FCSFAIL
31           pass frames with failed FCS (but you need to set the
32           RX_FLAG_FAILED_FCS_CRC for them)
33
34       FIF_PLCPFAIL
35           pass frames with failed PLCP CRC (but you need to set the
36           RX_FLAG_FAILED_PLCP_CRC for them
37
38       FIF_BCN_PRBRESP_PROMISC
39           This flag is set during scanning to indicate to the hardware that
40           it should not filter beacons or probe responses by BSSID. Filtering
41           them can greatly reduce the amount of processing mac80211 needs to
42           do and the amount of CPU wakeups, so you should honour this flag if
43           possible.
44
45       FIF_CONTROL
46           pass control frames (except for PS Poll), if PROMISC_IN_BSS is not
47           set then only those addressed to this station.
48
49       FIF_OTHER_BSS
50           pass frames destined to other BSSes
51
52       FIF_PSPOLL
53           pass PS Poll frames, if PROMISC_IN_BSS is not set then only those
54           addressed to this station.
55

FRAME FILTERING

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