IEEE80211_IOC_SCAN_REQ. 732 * 733 * Active scans cause ProbeRequest frames to be issued for each 734 * specified ssid and, by default, a broadcast ProbeRequest frame. 735 * The set of ssid's is specified in the request. 736 * 737 * By default the scan will cause a BSS to be joined (in station/adhoc 738 * mode) or a channel to be selected for operation (hostap mode). 739 * To disable that specify IEEE80211_IOC_SCAN_NOPICK and if the 740 * 741 * If the station is currently associated to an AP then a scan request 742 * will cause the station to leave the current channel and potentially 743 * miss frames from the AP. Alternatively the station may notify the 744 * AP that it is going into power save mode before it leaves the channel. 745 * This ensures frames for the station are buffered by the AP. This is 746 * termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN 747 * flag. Background scans may take longer than foreground scans and may 748 * be preempted by traffic. If a station is not associated to an AP 749 * then a request for a background scan is automatically done in the 750 * foreground. 751 * 752 * The results of the scan request are cached by the system. This 753 * information is aged out and/or invalidated based on events like not 754 * being able to associated to an AP. To flush the current cache 755 * contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may 756 * be specified. 757 * 758 * By default the scan will be done until a suitable AP is located 759 * or a channel is found for use. A scan can also be constrained 760 * to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more 761 * than a specified duration. 762 */ 763struct ieee80211_scan_req { 764 int sr_flags; 765#define IEEE80211_IOC_SCAN_NOPICK 0x00001 /* scan only, no selection */ 766#define IEEE80211_IOC_SCAN_ACTIVE 0x00002 /* active scan (probe req) */ 767#define IEEE80211_IOC_SCAN_PICK1ST 0x00004 /* ``hey sailor'' mode */ 768#define IEEE80211_IOC_SCAN_BGSCAN 0x00008 /* bg scan, exit ps at end */ 769#define IEEE80211_IOC_SCAN_ONCE 0x00010 /* do one complete pass */ 770#define IEEE80211_IOC_SCAN_NOBCAST 0x00020 /* don't send bcast probe req */ 771#define IEEE80211_IOC_SCAN_NOJOIN 0x00040 /* no auto-sequencing */ 772#define IEEE80211_IOC_SCAN_FLUSH 0x10000 /* flush scan cache first */ 773#define IEEE80211_IOC_SCAN_CHECK 0x20000 /* check scan cache first */ 774 u_int sr_duration; /* duration (ms) */ 775#define IEEE80211_IOC_SCAN_DURATION_MIN 1 776#define IEEE80211_IOC_SCAN_DURATION_MAX 0x7fffffff 777#define IEEE80211_IOC_SCAN_FOREVER IEEE80211_IOC_SCAN_DURATION_MAX 778 u_int sr_mindwell; /* min channel dwelltime (ms) */ 779 u_int sr_maxdwell; /* max channel dwelltime (ms) */ 780 int sr_nssid; 781#define IEEE80211_IOC_SCAN_MAX_SSID 3 782 struct { 783 int len; /* length in bytes */ 784 uint8_t ssid[IEEE80211_NWID_LEN]; /* ssid contents */ 785 } sr_ssid[IEEE80211_IOC_SCAN_MAX_SSID]; 786}; 787 788/* 789 * Scan result data returned for IEEE80211_IOC_SCAN_RESULTS. 790 * Each result is a fixed size structure followed by a variable 791 * length SSID and one or more variable length information elements. 792 * The size of each variable length item is found in the fixed 793 * size structure and the entire length of the record is specified 794 * in isr_len.
