[dpdk-dev] [RFC 1/4] ethdev: support rss level on tunnel

[Xueming Li]

There was no RSS hash fields level definition on tunnel, implementations
default RSS on tunnel to outer or inner. Adding rss level enable users
to specifiy the tunnel level of RSS hash fields.

0:  outer most,
1:  inner,
-1: inner most(PMD auto detection if nested tunnel specified in fields)
