tab Vs spaces :D

I am not sure what is the most followed convention in DPDK.
I thought most of alignments were done with spaces only.
I mean spaces before an end-of-line comment:

struct foo {
	int an_interesting_field;  /* mandatory */
	char poor_field;           /* optional thing */
}

That was my understanding too: tabs for indentation, spaces for alignment.
