3092 bit1-7: Bitmap Offset (logically Bitmap_Offset = Bitmap_Control & 0xFE).
3093 4 n Partial Virtual Bitmap
3094 Visible part of traffic-indication bitmap.
3095 Full bitmap consists of 2008 bits (251 octets) such that bit number N

3097 in octet number N/8 where the low-order bit of each octet is bit0,
3098 and the high order bit is bit7.
3099 Each set bit in virtual bitmap corresponds to traffic buffered by AP

3101 Partial Virtual Bitmap shows a part of bitmap which has non-zero.
3102 Bitmap Offset is a number of skipped zero octets (see above).
3103 'Missing' octets at the tail are also assumed to be zero.
3104 Example: Length=6, Bitmap_Offset=2, Partial_Virtual_Bitmap=55 55 55
3105 This means that traffic-indication bitmap is:
