issued for each 751 * specified ssid and, by default, a broadcast ProbeRequest frame. 752 * The set of ssid's is specified in the request. 753 * 754 * By default the scan will cause a BSS to be joined

associated to an AP then a scan request 759 * will cause the station to leave the current channel and potentially 760 * miss frames from the AP. Alternatively the station may notify the 761 * AP that it is going into power save mode before it leaves the channel. 762 * This ensures frames for the station are buffered by the AP. This is 763 * termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN 764 * flag. Background scans may take longer than foreground scans and may 765 * be preempted by traffic. If a station is not associated to an AP 766 * then a request for a background scan is automatically done in the 767 * foreground. 768 * 769 * The results of the scan request are cached by the system. This 770 * information is aged out and/or invalidated based on events like not 771 * being able to associated to an AP. To flush the current cache 772 * contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may 773 * be specified. 774 * 775 * By default the scan will be done until a suitable AP is located 776 * or a channel is found for use. A scan can also be constrained 777 * to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more 778 * than a specified duration. 779 */ 780 struct ieee80211_scan_req { 781 int sr_flags; 782 #define IEEE80211_IOC_SCAN_NOPICK 0x00001 /* scan only, no selection */ 783 #define IEEE80211_IOC_SCAN_ACTIVE 0x00002 /* active scan (probe req) */ 784 #define IEEE80211_IOC_SCAN_PICK1ST 0x00004 /* ``hey sailor'' mode */ 785 #define IEEE80211_IOC_SCAN_BGSCAN 0x00008 /* bg scan, exit ps at end */ 786 #define IEEE80211_IOC_SCAN_ONCE 0x00010 /* do one complete pass */ 787 #define IEEE80211_IOC_SCAN_NOBCAST 0x00020 /* don't send bcast probe req */ 788 #define IEEE80211_IOC_SCAN_NOJOIN 0x00040 /* no auto-sequencing */ 789 #define IEEE80211_IOC_SCAN_FLUSH 0x10000 /* flush scan cache first */ 790 #define IEEE80211_IOC_SCAN_CHECK 0x20000 /* check scan cache first */ 791 u_int sr_duration; /* duration (ms) */ 792 #define IEEE80211_IOC_SCAN_DURATION_MIN 1 793 #define IEEE80211_IOC_SCAN_DURATION_MAX 0x7fffffff 794 #define IEEE80211_IOC_SCAN_FOREVER IEEE80211_IOC_SCAN_DURATION_MAX 795 u_int sr_mindwell; /* min channel dwelltime (ms) */ 796 u_int sr_maxdwell; /* max channel dwelltime (ms) */ 797 int sr_nssid; 798 #define IEEE80211_IOC_SCAN_MAX_SSID 3 799 struct { 800 int len; /* length in bytes */ 801 uint8_t ssid[IEEE80211_NWID_LEN]; /* ssid contents */ 802 } sr_ssid[IEEE80211_IOC_SCAN_MAX_SSID]; 803 }; 804 805 /* 806 * Scan result data returned for IEEE80211_IOC_SCAN_RESULTS. 807 * Each result is a fixed size structure followed by a variable 808 * length SSID and one or more variable length information elements. 809 * The size of each variable length item is found in the fixed 810 * size structure and the entire length of the record is specified 811 * in isr_len.
