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 app/test-pmd/cmdline.c | 566 ++++++++++++++++++++++++++++++++++= ++++ lib/librte_ether/rte_eth_ctrl.h | 75 +++++ lib/librte_pmd_i40e/i40e_ethdev.c | 467 ++++++++++++++++++++++++++++++- 3 files changed, 1100 insertions(+), 8 deletions(-) -- 1.8.1.4
