From: Kiran Kumar K <kirankumark@marvell.com>
This patch reserves 2 bits as input selection to select Inner and
outer encapsulation level for RSS computation. It is combined with existing
ETH_RSS_* to choose Inner or outer layers.
This functionality already exists in rte_flow through level parameter in
RSS action configuration rte_flow_action_rss.

V8 Changes:
* Re-worked the level parameters. Added as PMD_DEFAULT, LEVEL_OUTERMOST,
LEVEL_INNERMOST
