3042 Visible part of traffic-indication bitmap.
3043 Full bitmap consists of 2008 bits (251 octets) such that bit number N

3045 in octet number N/8 where the low-order bit of each octet is bit0,
3046 and the high order bit is bit7.
3047 Each set bit in virtual bitmap corresponds to traffic buffered by AP
3048 for a specific station (with corresponding AID?).
3049 Partial Virtual Bitmap shows a part of bitmap which has non-zero.
3050 Bitmap Offset is a number of skipped zero octets (see above).
3051 'Missing' octets at the tail are also assumed to be zero.
3052 Example: Length=6, Bitmap_Offset=2, Partial_Virtual_Bitmap=55 55 55
3053 This means that traffic-indication bitmap is:
