To enable l3fwd application to be built\nwhen the eventdev library is disabled, we need to compile in the\neventdev support conditionally. Thankfully, the eventdev support is\npretty self-contained, with only the main.c file having more than a\ncouple of ifdefs.\n\nSigned-off-by: Bruce Richardson <bruce.richardson@intel.com>\n---\n
