t2.c also uses rte_mbuf, so same story for both.

I believe it is not:
$ find lib config -type f | xargs grep CACHE_LINE_MIN_SIZE
lib/librte_eal/linux/eal/include/rte_kni_common.h:#define RTE_CACHE_LINE_MIN_SIZE 64
lib/librte_eal/linux/eal/include/rte_kni_common.h: char pad3[8] __attribute__((__aligned__(RTE_CACHE_LINE_MIN_SIZE)));
lib/librte_eal/common/include/rte_memory.h:#define RTE_CACHE_LINE_MIN_SIZE 64 /**< Minimum Cache line size. */
lib/librte_eal/common/include/rte_memory.h:#define __rte_cache_min_aligned __rte_aligned(RTE_CACHE_LINE_MIN_SIZE)
