[v9,0/9] support setting and querying RSS algorithms

  This patchset is to support setting and querying RSS algorithms.
For this purpose, field "rss_algo_capa" is added to ``rte_eth_dev_info``
and field "algorithm" is added to ``rte_eth_rss_conf``.
The drivers should reports their "rss_algo_capa" if they support
updating RSS algorithms. Otherwise, the "rss_algo_capa" is set to
RTE_ETH_HASH_ALGO_CAPA_MASK(DEFAULT). The app configures RSS algorithms
by field "algorithm" and the related API should verify "algorithm" with
"rss_algo_capa".
