[dpdk-dev] [PATCH v5 0/5] Support configuring hash functions

[Helin Zhang <helin.zhang@intel.com>]

These patches mainly support configuring hash functions.
In detail,
 - It can get or set hash functions.
 - It can configure symmetric hash functions.
   * Get/set symmetric hash enable per port.
   * Get/set symmetric hash enable per 'PCTYPE'.
   * Get/set filter swap configurations.
 - Six commands have been implemented in testpmd to support
   testing above.
   * get_sym_hash_ena_per_port
   * set_sym_hash_ena_per_port
   * get_sym_hash_ena_per_pctype
   * set_sym_hash_ena_per_pctype
   * get_filter_swap
   * set_filter_swap
   * get_hash_function
   * set_hash_function
Note that 'PCTYPE' means 'Packet Classification Type'.

It also uses prepared constant hash keys to replace runtime
generating hash keys. Global initialization is added to put
global registers to an initial state, as global registers
can be reset by global reset only.

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.

Helin Zhang (5):
  i40e: Use constant random hash keys
  ethdev: add enum type and relevant structures for hash filter control
  i40e: add hash filter control implementation
  i40e: add hardware initialization
  app/testpmd: add commands to support hash filter
