[dpdk-dev] [PATCH 00/10] net/softnic: implement metering and policing API

[Jasvinder Singh]

This patchset adds the metering and policing API support for the
softnic. The metering and policing action can be enabled through the
flow rules.

This series is prepared on top of following patchset;
https://mails.dpdk.org/archives/dev/2018-September/110998.html

Jasvinder Singh (10):
  net/softnic: add metering and policing support
  net/softnic: add meter profile
  net/softnic: delete meter profile
  net/softnic: create meter object
  net/softnic: destroy meter object
  net/softnic: update meter profile
  net/softnic: update dscp table
  net/softnic: update policer actions
  net/softnic: meter stats read
  net/softnic: enable meter action using flow rule

[dpdk-dev] [PATCH v2 00/10] net/softnic: implement metering and policing API

[Jasvinder Singh]

This patchset adds the metering and policing API support for the
softnic. The metering and policing action can be enabled through the
flow rules.

This series is prepared on top of following patchset;
https://mails.dpdk.org/archives/dev/2018-September/111379.html

v2 changes:
- fix copyright year for rte_eth_softnic_meter.c
- Place all checks in a separate functions while creating meter object
- Use softnic_pipeline_table_mtr_profile_add() api to add meter profile
  instead of implementing new function
- Use stats type indicator to determine the stats_mask for meter stats read 
 
Jasvinder Singh (10):
  net/softnic: add metering and policing support
  net/softnic: add meter profile
  net/softnic: delete meter profile
  net/softnic: create meter object
  net/softnic: destroy meter object
  net/softnic: update meter profile
  net/softnic: update dscp table
  net/softnic: update policer actions
  net/softnic: meter stats read
  net/softnic: enable flow rule with meter action

[dpdk-dev] [PATCH v3 00/10] net/softnic: implement metering and policing API

[Jasvinder Singh]

This series is prepared on top of following patchset;
https://mails.dpdk.org/archives/dev/2018-September/111379.html

v3 changes:
- update pipeline table with meter profiles
- update pipeline table with dscp table entry update

v2 changes:
- fix copyright year for rte_eth_softnic_meter.c
- Place all checks in a separate functions while creating meter object
- Use softnic_pipeline_table_mtr_profile_add() api to add meter profile
  instead of implementing new function
- Use stats type indicator to determine the stats_mask for meter stats read 
 
Jasvinder Singh (10):
  net/softnic: add metering and policing support
  net/softnic: add meter profile
  net/softnic: delete meter profile
  net/softnic: create meter object
  net/softnic: destroy meter object
  net/softnic: update meter profile
  net/softnic: update dscp table
  net/softnic: update policer actions

[dpdk-dev] [PATCH v4 00/10] net/softnic: implement metering and policing API

[Jasvinder Singh]

This series is prepared on top of following patchset;
https://mails.dpdk.org/archives/dev/2018-September/111379.html

v4 changes
- introduce the table meter profile check in softnic pipeline table meter
  profile add function (rte_eth_softnic_thread.c)
- change the table action check function to more generic form
  softnic_table_is_action_enabled() (rte_eth_softnic_flow.c)
  
v3 changes:
- update pipeline table with meter profiles
- update pipeline table with dscp table entry update

v2 changes:
- fix copyright year for rte_eth_softnic_meter.c
- Place all checks in a separate functions while creating meter object
- Use softnic_pipeline_table_mtr_profile_add() api to add meter profile
  instead of implementing new function
- Use stats type indicator to determine the stats_mask for meter stats read

[dpdk-dev] [PATCH v5 00/10] net/softnic: implement metering and policing API

[Jasvinder Singh]

This series is prepared on top of following patchset;
https://mails.dpdk.org/archives/dev/2018-September/111379.html

v5 changes
- fix wrong parameter in memcpy for table meter profile update
  
v4 changes
- introduce the table meter profile check in softnic pipeline table meter
  profile add function (rte_eth_softnic_thread.c)
- change the table action check function to more generic form
  softnic_table_is_action_enabled() (rte_eth_softnic_flow.c)
  
v3 changes:
- update pipeline table with meter profiles
- update pipeline table with dscp table entry update

v2 changes:
- fix copyright year for rte_eth_softnic_meter.c
- Place all checks in a separate functions while creating meter object
- Use softnic_pipeline_table_mtr_profile_add() api to add meter profile
  instead of implementing new function
- Use stats type indicator to determine the stats_mask for meter stats read 
 
Jasvinder Singh (10):
  net/softnic: add metering and policing support
