This code is functioning fine in dpdk 23.11
But giving following error in 24.11

================================================================
Thread 106 received signal SIGSEGV, Segmentation fault.

0x000000000041a4de in rte_eth_tx_burst (port_id=0, queue_id=0,
tx_pkts=0x17f8b3180, nb_pkts=4096) at /usr/include/dpdk/rte_ethdev.h:6425

Do a debug build (with -Dbuildtype=debug) and run it under gdb.
You might also want to enable ETHDEV_DEBUG and MBUF_DEBUG in rte_config.h
