Struct Dot15d4FcsLayer 

pub struct Dot15d4FcsLayer {
    pub index: LayerIndex,
}

IEEE 802.15.4 MAC frame with FCS (2-byte CRC at the end).

This is a drop-in replacement for Dot15d4Layer that expects a 2-byte FCS/checksum at the end of the frame, and produces one when building.

Fields

index: LayerIndex
