            Bug ID: 1698
           Summary: rte_eth_rx_burst causes segmentation fault when
                    encountered in a Secondary process
           Product: DPDK
           Version: 23.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: examples
          Assignee: dev@dpdk.org
          Reporter: reuben.koshy@vvdntech.in
  Target Milestone: ---

Created attachment 311
  --> https://bugs.dpdk.org/attachment.cgi?id=311&action=edit
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.

DPDK Version : 23.11
