scan requested with 716 * IEEE80211_IOC_SCAN_REQ. 717 * 718 * Active scans cause ProbeRequest frames to be issued for each 719 * specified ssid and, by default, a broadcast ProbeRequest frame. 720 * The set of ssid's is specified in the request. 721 * 722 * By default the scan will cause a BSS to be joined (in station/adhoc 723 * mode) or a channel to be selected for operation (hostap mode). 724 * To disable that specify IEEE80211_IOC_SCAN_NOPICK and if the 725 * 726 * If the station is currently associated to an AP then a scan request 727 * will cause the station to leave the current channel and potentially 728 * miss frames from the AP. Alternatively the station may notify the 729 * AP that it is going into power save mode before it leaves the channel. 730 * This ensures frames for the station are buffered by the AP. This is 731 * termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN 732 * flag. Background scans may take longer than foreground scans and may 733 * be preempted by traffic. If a station is not associated to an AP 734 * then a request for a background scan is automatically done in the 735 * foreground. 736 * 737 * The results of the scan request are cached by the system. This 738 * information is aged out and/or invalidated based on events like not 739 * being able to associated to an AP. To flush the current cache 740 * contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may 741 * be specified. 742 * 743 * By default the scan will be done until a suitable AP is located 744 * or a channel is found for use. A scan can also be constrained 745 * to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more 746 * than a specified duration. 747 */ 748struct ieee80211_scan_req { 749 int sr_flags; 750#define IEEE80211_IOC_SCAN_NOPICK 0x00001 /* scan only, no selection */ 751#define IEEE80211_IOC_SCAN_ACTIVE 0x00002 /* active scan (probe req) */ 752#define IEEE80211_IOC_SCAN_PICK1ST 0x00004 /* ``hey sailor'' mode */ 753#define IEEE80211_IOC_SCAN_BGSCAN 0x00008 /* bg scan, exit ps at end */ 754#define IEEE80211_IOC_SCAN_ONCE 0x00010 /* do one complete pass */ 755#define IEEE80211_IOC_SCAN_NOBCAST 0x00020 /* don't send bcast probe req */ 756#define IEEE80211_IOC_SCAN_NOJOIN 0x00040 /* no auto-sequencing */ 757#define IEEE80211_IOC_SCAN_FLUSH 0x10000 /* flush scan cache first */ 758#define IEEE80211_IOC_SCAN_CHECK 0x20000 /* check scan cache first */ 759 u_int sr_duration; /* duration (ms) */ 760#define IEEE80211_IOC_SCAN_DURATION_MIN 1 761#define IEEE80211_IOC_SCAN_DURATION_MAX 0x7fffffff 762#define IEEE80211_IOC_SCAN_FOREVER IEEE80211_IOC_SCAN_DURATION_MAX 763 u_int sr_mindwell; /* min channel dwelltime (ms) */ 764 u_int sr_maxdwell; /* max channel dwelltime (ms) */ 765 int sr_nssid; 766#define IEEE80211_IOC_SCAN_MAX_SSID 3 767 struct { 768 int len; /* length in bytes */ 769 uint8_t ssid[IEEE80211_NWID_LEN]; /* ssid contents */ 770 } sr_ssid[IEEE80211_IOC_SCAN_MAX_SSID]; 771}; 772 773/* 774 * Scan result data returned for IEEE80211_IOC_SCAN_RESULTS. 775 * Each result is a fixed size structure followed by a variable 776 * length SSID and one or more variable length information elements. 777 * The size of each variable length item is found in the fixed 778 * size structure and the entire length of the record is specified 779 * in isr_len.
