1. A device comprising:
a medium access control (MAC) layer; and
a physical (PHY) layer, the PHY layer configured to:
receive a data packet via a communication medium,
in response to detecting a first preamble in the data packet and a second preamble in the data packet, set a preamble indication primitive to a first value,
in response to detecting the first preamble and failing to detect the second preamble, set the preamble indication primitive to a second value different from the first value, and
provide the preamble indication primitive to the MAC layer.
