From: Kiran Kumar K <kirankum...@marvell.com>
Adding support to set RSS level from ethdev config.
level-0 will requests the default behavior.
level-1 will requests RSS to be performed on the outermost packet
encapsulation level.
level-2 will request RSS to be performed on the specified inner packet
encapsulation level, from outermost to innermost.
