3142 [802.11 7.3.2.6] TIM information element:
3143 - 1 EID
3144 - 1 Length
3145 1 1 DTIM Count
3146 indicates how many beacons (including this) appear before next DTIM
3147 (0=this one is a DTIM)
3148 2 1 DTIM Period
3149 number of beacons between successive DTIMs
3150 (0=reserved, 1=all TIMs are DTIMs, 2=every other, etc)
3151 3 1 Bitmap Control
3152 bit0: Traffic Indicator bit associated with Assoc ID 0 (Bcast AID?)
3153 set to 1 in TIM elements with a value of 0 in the DTIM Count field
3154 when one or more broadcast or multicast frames are buffered at the AP.
3155 bit1-7: Bitmap Offset (logically Bitmap_Offset = Bitmap_Control & 0xFE).
3156 4 n Partial Virtual Bitmap
3157 Visible part of traffic-indication bitmap.
3158 Full bitmap consists of 2008 bits (251 octets) such that bit number N
3159 (0<=N<=2007) in the bitmap corresponds to bit number (N mod 8)
3160 in octet number N/8 where the low-order bit of each octet is bit0,
3161 and the high order bit is bit7.
3162 Each set bit in virtual bitmap corresponds to traffic buffered by AP
3163 for a specific station (with corresponding AID?).
3164 Partial Virtual Bitmap shows a part of bitmap which has non-zero.
3165 Bitmap Offset is a number of skipped zero octets (see above).
3166 'Missing' octets at the tail are also assumed to be zero.
3167 Example: Length=6, Bitmap_Offset=2, Partial_Virtual_Bitmap=55 55 55
3168 This means that traffic-indication bitmap is:
3169 00000000 00000000 01010101 01010101 01010101 00000000 00000000...
