Struct Dot11BlockAck 

pub struct Dot11BlockAck {
    pub offset: usize,
    pub len: usize,
}

802.11 Block Ack (BA) frame body.

After the 802.11 header (Addr1 + Addr2), contains:

• BA Control (2 bytes, little-endian)
• Starting Sequence Control (2 bytes, little-endian)
• Block Ack Bitmap (variable, typically 128 bytes for basic BA)

Fields

offset: usize

len: usize
