enum gnrc_mac_tx_feedback_t
TX_FEEDBACK_UNDEF = 0
Transmission just start, no Tx feedback yet.

No ACK for the transmitted packet.
TX_FEEDBACK_BUSY
found medium busy when doing transmission
struct gnrc_mac_rx_t

MAC internal type for storing reception state parameters and state machines.

This structure can be extended to contain more needed states and parameters. Please guard them by appropriate #ifdef directives when applicable.

priority_pktqueue.h::gnrc_priority_pktqueue_t queue

RX packet queue.

include/net/gnrc/pkt.h::gnrc_pktsnip_t * dispatch_buffer()

dispatch packet buffer

struct gnrc_mac_tx_neighbor_t

type for storing states of TX neighbor node.

uint8_t l2_addr()

Address of neighbor node.

uint8_t l2_addr_len

Neighbor address length.

uint32_t phase

Neighbor’s wake-up Phase.

priority_pktqueue.h::gnrc_priority_pktqueue_t queue

TX queue for this particular Neighbor.

struct gnrc_mac_tx_t

MAC internal type for storing transmission state parameters and state machines.

This structure can be extended to contain more needed states and parameters. Please guard them by appropriate #ifdef directives when applicable.

gnrc_mac_tx_neighbor_t neighbors()

Neighbor information units for one-hop neighbors.

First unit is for broadcast (+1)

gnrc_mac_tx_neighbor_t * current_neighbor

Neighbor information unit of destination node to which the current packet will be sent.

priority_pktqueue.h::gnrc_priority_pktqueue_t queue

If neighbor queues is not used, define a single queue for managing TX packets.

include/net/gnrc/pkt.h::gnrc_pktsnip_t * packet

currently scheduled packet for sending
