This is the screenshot of the log that appears when the secondary process
tries to execute tx_burst
I took a copy of the simple_mp main program from multi_process within the DPDK
examples and modified it by adding bonding and allowing it to send dummy
packets.
Two bonds are created, both are under the Active backup mode. This is done by
the primary process.
Once the bonds are created, configured and started, the transmisssion of dummy
packets starts. When tx_burst is run for the primary process, the transmission
of packets occur without any issue.
However, when the tx_burst is encountered during the Secondary process with the
primary process running in another terminal, a segmentation error occurs.
