issued for each 753 * specified ssid and, by default, a broadcast ProbeRequest frame. 754 * The set of ssid's is specified in the request. 755 * 756 * By default the scan will cause a BSS to be joined

associated to an AP then a scan request 761 * will cause the station to leave the current channel and potentially 762 * miss frames from the AP. Alternatively the station may notify the 763 * AP that it is going into power save mode before it leaves the channel. 764 * This ensures frames for the station are buffered by the AP. This is 765 * termed a ``bg scan'' and is requested with the IEEE80211_IOC_SCAN_BGSCAN 766 * flag. Background scans may take longer than foreground scans and may 767 * be preempted by traffic. If a station is not associated to an AP 768 * then a request for a background scan is automatically done in the 769 * foreground. 770 * 771 * The results of the scan request are cached by the system. This 772 * information is aged out and/or invalidated based on events like not 773 * being able to associated to an AP. To flush the current cache 774 * contents before doing a scan the IEEE80211_IOC_SCAN_FLUSH flag may 775 * be specified. 776 * 777 * By default the scan will be done until a suitable AP is located 778 * or a channel is found for use. A scan can also be constrained 779 * to be done once (IEEE80211_IOC_SCAN_ONCE) or to last for no more 780 * than a specified duration. 781 */ 782 struct ieee80211_scan_req { 783 int sr_flags; 784 #define IEEE80211_IOC_SCAN_NOPICK 0x00001 /* scan only, no selection */ 785 #define IEEE80211_IOC_SCAN_ACTIVE 0x00002 /* active scan (probe req) */ 786 #define IEEE80211_IOC_SCAN_PICK1ST 0x00004 /* ``hey sailor'' mode */ 787 #define IEEE80211_IOC_SCAN_BGSCAN 0x00008 /* bg scan, exit ps at end */ 788 #define IEEE80211_IOC_SCAN_ONCE 0x00010 /* do one complete pass */ 789 #define IEEE80211_IOC_SCAN_NOBCAST 0x00020 /* don't send bcast probe req */ 790 #define IEEE80211_IOC_SCAN_NOJOIN 0x00040 /* no auto-sequencing */ 791 #define IEEE80211_IOC_SCAN_FLUSH 0x10000 /* flush scan cache first */ 792 #define IEEE80211_IOC_SCAN_CHECK 0x20000 /* check scan cache first */ 793 u_int sr_duration; /* duration (ms) */ 794 #define IEEE80211_IOC_SCAN_DURATION_MIN 1 795 #define IEEE80211_IOC_SCAN_DURATION_MAX 0x7fffffff 796 #define IEEE80211_IOC_SCAN_FOREVER IEEE80211_IOC_SCAN_DURATION_MAX 797 u_int sr_mindwell; /* min channel dwelltime (ms) */ 798 u_int sr_maxdwell; /* max channel dwelltime (ms) */ 799 int sr_nssid; 800 #define IEEE80211_IOC_SCAN_MAX_SSID 3 801 struct { 802 int len; /* length in bytes */ 803 uint8_t ssid[IEEE80211_NWID_LEN]; /* ssid contents */ 804 } sr_ssid[IEEE80211_IOC_SCAN_MAX_SSID]; 805 }; 806 807 /* 808 * Scan result data returned for IEEE80211_IOC_SCAN_RESULTS. 809 * Each result is a fixed size structure followed by a variable 810 * length SSID and one or more variable length information elements. 811 * The size of each variable length item is found in the fixed 812 * size structure and the entire length of the record is specified 813 * in isr_len.
