[dpdk-dev] [PATCH v2 0/6] Support configuring hash functions

[Helin Zhang]

These pathches mainly support configuring hash functions.
In detail,
 - It can select Toeplitz or simple XOR 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.
   * 'is_command_supported', to check if a feature (command)
     is supported on a port.
   * 'rx_classification_filter_ctl', a common API to execute
     specific command of each feature.
 - Seven commands are implemented in testpmd to support
   testing above.
Note that 'PCTYPE' means 'Packet Classification Type'.

Helin Zhang (6):
  ethdev: rename macros of packet classification type
  ethdev: add new ops of 'is_command_supported' and    
    'rx_classification_filter_ctl'
  i40e: support of 'rx_classification_filter_ctl'
  i40e: support of 'is_command_supported'
  i40e: Initialize hash function during port initialization.
  app/testpmd: add commands for configuring hash functions

[dpdk-dev] [PATCH v2 1/6] ethdev: rename macros of packet classification type

[Helin Zhang]

For better understanding, 'PCTYPE' which represents
'Packet Classification Type' is used to replace 'RSS'
in the name of shift macros.

[dpdk-dev] [PATCH v2 2/6] ethdev: add new ops of 'is_command_supported' and 'rx_classification_filter_ctl'

[Helin Zhang]

Two ops of 'is_command_supported' and
'rx_classification_filter_ctl' are added. New header
file of 'rte_eth_features.h' is added.
* 'is_command_supported': It is for capability discovery,
  that is to check if specific feature/command is
  supported on a port.
* 'rx_classification_filter_ctl': It is for receive
  classification filter configuring. e.g. selecting hash
  function, possibly configuring flow director. It is a
  common API where a lot of commands can be implemented
  for different sub features, to avoid defining quite a
  lot of ops for device specific features.
* 'rte_eth_features.h': It includes all the feature
  commands which can be checked and processed in above
  two ops. Also it may include other commands for future
  implementations.

[dpdk-dev] [PATCH v2 3/6] i40e: support of 'rx_classification_filter_ctl'

[Helin Zhang]

'rx_classification_filter_ctl' was defined as a common API
for receive classification filter features. Eight commands
has been implemented for selecting hash functions of
'Toeplitz' and 'Simple XOR', and configuring symmetric hash
functions. In detail,
RTE_CMD_GET_SYM_HASH_ENABLE_PER_PCTYPE:
 - Get symmetric hash enable configuration per 'PCTYPE'.
RTE_CMD_SET_SYM_HASH_ENABLE_PER_PCTYPE:
 - Set symmetric hash enable configuration per 'PCTYPE'.
RTE_CMD_GET_SYM_HASH_ENABLE_PER_PORT:
 - Get symmetric hash enable configuration per port.
RTE_CMD_SET_SYM_HASH_ENABLE_PER_PORT:
 - Set symmetric hash enable configuration per port.
RTE_CMD_GET_FILTER_SWAP:
 - Get filter swap configurations.
RTE_CMD_SET_FILTER_SWAP:
 - Set filter swap configurations.
RTE_CMD_GET_HASH_FUNCTION:
 - Get current hash function.
RTE_CMD_SET_HASH_FUNCTION:
 - Set hash function of 'Toeplitz' or 'Simple XOR'.
Note that 'PCTYPE' means 'Packet Classification Type'.

[dpdk-dev] [PATCH v2 4/6] i40e: support of 'is_command_supported'

[Helin Zhang]

'is_command_supported' is defined for the capability discovery.
Actually it is to check if a command (feature) is supported on
a specific type of NIC port. Now i40e supports below eight
commands. Of cause, more commands can be supported later.
 - RTE_CMD_GET_SYM_HASH_ENABLE_PER_PCTYPE
 - RTE_CMD_SET_SYM_HASH_ENABLE_PER_PCTYPE
 - RTE_CMD_GET_SYM_HASH_ENABLE_PER_PORT
 - RTE_CMD_SET_SYM_HASH_ENABLE_PER_PORT
 - RTE_CMD_GET_FILTER_SWAP
 - RTE_CMD_SET_FILTER_SWAP
 - RTE_CMD_GET_HASH_FUNCTION
 - RTE_CMD_SET_HASH_FUNCTION

[dpdk-dev] [PATCH v2 5/6] i40e: Initialize hash function during port initialization.

[Helin Zhang]

As hash function are configured in gloabal registers, those
registers will not be reloaded unless a gloabl NIC hardware
reset. That means a DPDK application launch will not load
the default configuration of hash functions. It needs an
initialization of those registers during the port
initialization to make sure all those registers are in an
expected state.

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'

I have tested this patch on fedora20 with Fortville NIC.
The hash function toeplitz/simple XOR/ symmetric all works well
for ip/udp both ipv4 and ipv6 packets in testpmd support RSS.

Hi Thomas

Would you please help to apply it as soon as possible, as another developer here who is now developing another feature (Flow Director) which has dependency on these patches?
Thank you very much!
