By definition, RSS involves some kind of hash algorithm, usually Toeplitz.
Until now it could not be modified on a flow rule basis and PMDs had to
always assume RTE_ETH_HASH_FUNCTION_DEFAULT, which remains the default
behavior when unspecified (0).
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

v3 changes:
- Although RTE_ETH_HASH_FUNCTION_DEFAULT is defined as 0, made comparisons
more explicit where doing so would clarify the code.
- Updated sfc to include Toeplitz as the other allowed value.
Both according to Andrew's suggestions [1].
