* @brief This function test the `gnrc_mac_queue_tx_packet()`, to see whether it can

* In case when the `gnrc_mac_tx_neighbor_t` structure is in used (indicated by
* by `GNRC_MAC_NEIGHBOR_COUNT != 0`), `test_gnrc_mac_queue_tx_packet()` successively
* queues 4 packets, which are pkt1, pkt2, pkt3 and pkt_bcast, into a defined `tx`
* (type of `gnrc_mac_tx_t`). Pkt1, pkt2 have the same destination address of "0x76b6",
* , pkt3 is heading for "0x447e", while pkt_bcast is for broadcasting.
* Expected results: pkt1 and pkt2 should be queued to `tx::neighbors[1]::queue`,
* pkt3 should be queued to `tx::neighbors[2]::queue`, while pkt_bcast should be
* queued to `tx::neighbors[0]::queue`.
