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.
- 'ethdev' level interfaces are added.
* 'rte_eth_dev_filter_supported', to check if a filter control
is supported on a port.
* 'rte_eth_dev_filter_ctrl', a common API to execute
specific filter control.
- 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'.
v4 changes:
* Fixed a bug in testpmd to support 'set_sym_hash_ena_per_port'.
