IEEE80211_RAD(9) Utility functions STRUCT IEEE80211_RAD(9) NAME
struct_ieee80211_radiotap_iterator - tracks walk thru present radiotap args SYNOPSIS
struct ieee80211_radiotap_iterator { struct ieee80211_radiotap_header * _rtheader; const struct ieee80211_radiotap_vendor_namespaces * _vns; const struct ieee80211_radiotap_namespace * current_namespace; unsigned char * _arg; unsigned char * _next_ns_data; __le32 * _next_bitmap; unsigned char * this_arg; int this_arg_index; int this_arg_size; int is_radiotap_ns; int _max_length; int _arg_index; uint32_t _bitmap_shifter; int _reset_on_ext; }; MEMBERS
_rtheader pointer to the radiotap header we are walking through _vns vendor namespace definitions current_namespace pointer to the current namespace definition (or internally NULL if the current namespace is unknown) _arg next argument pointer _next_ns_data beginning of the next namespace's data _next_bitmap internal pointer to next present u32 this_arg pointer to current radiotap arg; it is valid after each call to ieee80211_radiotap_iterator_next but also after ieee80211_radiotap_iterator_init where it will point to the beginning of the actual data portion this_arg_index index of current arg, valid after each successful call to ieee80211_radiotap_iterator_next this_arg_size length of the current arg, for convenience is_radiotap_ns indicates whether the current namespace is the default radiotap namespace or not _max_length length of radiotap header in cpu byte ordering _arg_index next argument index _bitmap_shifter internal shifter for curr u32 bitmap, b0 set == arg present _reset_on_ext internal; reset the arg index to 0 when going to the next bitmap word DESCRIPTION
Describes the radiotap parser state. Fields prefixed with an underscore must not be used by users of the parser, only by the parser internally. AUTHOR

IEEE80211_CHA(9) Device registration STRUCT IEEE80211_CHA(9) NAME
struct_ieee80211_channel - channel definition SYNOPSIS
struct ieee80211_channel { enum ieee80211_band band; u16 center_freq; u16 hw_value; u32 flags; int max_antenna_gain; int max_power; int max_reg_power; bool beacon_found; u32 orig_flags; int orig_mag; int orig_mpwr; enum nl80211_dfs_state dfs_state; unsigned long dfs_state_entered; }; MEMBERS
band band this channel belongs to. center_freq center frequency in MHz hw_value hardware-specific value for the channel flags channel flags from enum ieee80211_channel_flags. max_antenna_gain maximum antenna gain in dBi max_power maximum transmission power (in dBm) max_reg_power maximum regulatory transmission power (in dBm) beacon_found helper to regulatory code to indicate when a beacon has been found on this channel. Use regulatory_hint_found_beacon to enable this, this is useful only on 5 GHz band. orig_flags channel flags at registration time, used by regulatory code to support devices with additional restrictions orig_mag internal use orig_mpwr internal use dfs_state current state of this channel. Only relevant if radar is required on this channel. dfs_state_entered timestamp (jiffies) when the dfs state was entered. DESCRIPTION
This structure describes a single channel for use with cfg80211. AUTHOR
