Struct FrameControl

pub struct FrameControl {
    pub protocol_version: FrameProtocolVersion,
    pub frame_type: FrameType,
    pub frame_subtype: FrameSubType,
    pub flags: u8,
}

The very first two bytes of every frame contain the FrameControl header. Wikipedia article

First byte:

• bit_0-1: FrameProtocolVersion
• bit_2-3: FrameType
• bit_4-7: FrameSubType

The values of the remaining bytes depend on protocol version, frame type and sub type.

In the general case:

PV0 Second byte (Flags):

• bit_0 to_ds: Set if the frame is to be sent by the AP to the distribution system.
• bit_1 from_ds: Set if the frame is from the distribution system.
• bit_2 more_frag: Set if this frame is a fragment of a bigger frame and there are more fragments to follow.
• bit_3 retry: Set if this frame is a retransmission, maybe through the loss of an ACK.
• bit_4 power_mgmt: Indicates what power mode (save or active) the station will be in, once the frame has been sent.
• bit_5 more_data: Set by the AP to indicate that more frames are destined to a particular station that may be in power save mode. These frames will be buffered at the AP, so it can be sent once the station decides to become active.
• bit_6 protected: Set if the frame body is encrypted (protected)
• bit_7 order: Set if the frame is being sent according to the Strictly Ordered Class.
