A packet consists of a preamble, a start-of-frame delimiter and an Ethernet frame.
The Ethernet frame consists of the destination address, the source address, an optional
VLAN field, the length/type field, the payload and the frame check sequence.
Each address consists of 6 bytes where each byte consists of 8 bits. Bits are transferred
starting with the least significant bit.
