I am not going to be much help as I do not and have not used BIGIP.
I assume you have the Pktgen that supports bonding mode 4. The previous Pktgen version would not call tx_burst() unless it had something to send, which the bonding driver requires tx_burst() with zero packets at least at a given interval. The latest versions do call tx_burst() with zero pkts at least within the needed timing.
