There is a compile error in the "for" statement.

dpdk/drivers/net/i40e/i40e_ethdev.c:11561:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (uint32_t i = 0; i < p_list->p_count; i++) {

This is occurring with the following compiler:
gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3)
