* @brief More data will follow
*
* @details This flag signals that this packet is part of a burst of packets.
* The link layer implementation can choose to translate this flag into
* frame header bits to tell the remote node that more traffic will
* follow shortly. The most direct use case for this flag is to set it
* for fragmented packets in duty cycled networks to tell the remote
* node to keep its radio turned on after receiving the first fragment.
