 * This is the physical layer that sends and receives a packet
 *   - accept any type and length (<= PHY_MAX_PKT_LEN in phy_radio_msg.h) of packet
 *   - sending a packet: encoding and byte spooling
 *   - receiving a packet: decoding, byte buffering
 *   - Optional CRC check
 *   - interface to radio control and physical carrier sense
