These patches mainly support configuring hash functions. In detail,
- It can get/set global hash configurations.
* Get/set symmetric hash enable per flow type.
* Get/set hash function type.
- It can get/set symmetric hash enable per port.
- Four commands have been implemented in testpmd to support testing above.
* get_sym_hash_ena_per_port
* set_sym_hash_ena_per_port
* get_hash_global_config
* set_hash_global_config
It also uses constant hash keys to replace runtime generating hash keys.
Global initialization is added to correctly put registers to an initial state.
v3 changes:
* Removed renamings in rte_ethdev.h.
* Redesigned filter control API and its relevant structures/enums.
* Renamed header file from rte_eth_features.h to rte_eth_ctrol.h.
* Remove public header file of rte_i40e.h specific for i40e.
* Added hardware initialization function during port init.
* Used constant random hash keys in i40e PF.
* renamed the commands in testpmd based on the redesigned filter control API.
v4 changes:
* Fixed a bug in testpmd to support 'set_sym_hash_ena_per_port'.
v5 changes:
* Integrated with filter API defined recently.
* Remove all for filter API definition, as it has already defined and merged
recently.
v6 changes:
* Flow type strings are used to replace Packet Classification Types, to isolate
hardware specific things.
* Implemented the mapping function to convert RSS offload types to Packet
Classification Types, to isolate the real hardware specific things.
* Removed initialization of global registers in i40e PMD, as global registers
shouldn't be initialized per port.
* Added more annotations to get code more understandable.
* Corrected annotation format for documenation.
v7 changes:
* Removed swap configurations, as it is not allowed by hardware design.
* Put symmetric hash per flow type and hash function type into
'RTE_ETH_HASH_FILTER_GLOBAL_CONFIG', as they are controlling global registers
which will affects all the ports of the same NIC.
v8 changes:
* Removed redundant checks in i40e_ethdev.c.
* Solved compile errors on ICC.

ethdev: code style fixes
i40e: use constant as the default hash keys
i40e: support of controlling hash functions
app/testpmd: add commands to support hash functions
