[dpdk-dev] [PATCH v2 6/6] app/testpmd: add commands for configuring hash functions

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

Eight commands are added to configure hash functions.
They are,
 - i40e_get_sym_hash_ena_per_port
   Get symmetric hash enable per port.
 - i40e_set_sym_hash_ena_per_port
   Set symmetric hash enable per port.
 - i40e_get_sym_hash_ena_per_pctype
   Get symmetric hash enable per PCTYPE
   (Packet Classification Type).
 - i40e_set_sym_hash_ena_per_pctype
   Set symmetric hash enable per PCTYPE
   (Packet Classification Type).
 - i40e_get_filter_swap
   Get filter swap configurations.
 - i40e_set_filter_swap
   Set filter swap configurations.
 - i40e_get_hash_function
   Get hash function.
 - i40e_set_hash_function
   Set hash function to 'Toeplitz' or 'Simple XOR'
