[dpdk-dev] [PATCH v1] net/i40e: fix set rss hash function invalid

i40e can support following rss hash function types: default (toeplitz),
symmetric toeplitz, and simple_xor. However, when filter engine parses
pattern action, it only supports symmetric toeplitz & default (toeplitz).

Delete the hash function limitation when parsing pattern action.
