[Varghese, Vipin]

> Example BPF programs t1.c, t2.c, t3.c in folder examples/bpf are failing to

As a note, the file t3.c is one which fails to get compiled.

> The reason is changes in some core DPDK header files, that causes now inclusion

The definition for RTE_CACHE_LINE_MIN_SIZE is present in ` rte_config.h`. Using the same did not cause compilation issues. Is there specific reason not to use the same?

The code is tested and verified with clang6.0 and clang8.0 on Ubuntu 18.04.2 LTS.
