This patch series adds Flow Director support for Intel Ethernet
Controller E810 series using RTE_FLOW

- Patch 01-02 are FDIR init,teardown and configuration
- Remaining patches are FDIR RTE_FLOW enablement

The patchset depends on:
http://patchwork.dpdk.org/project/dpdk/list/?series=6420
---
v3:
* Get flow id in flexible descriptor
* Add vxlan tunnel rule support

v2:
* Move to flexible descriptor.
* Distinguish tunnel and non-tunnel rule.
* Add uninit function for fdir engine.
* Fix coding style.
* Change patch organization.
* Add release notes.

Beilei Xing (2):
  net/ice: enable flow director engine
  net/ice: configure HW FDIR rule

Yahui Cao (6):
  net/ice: add FDIR create and destroy
  net/ice: enable FDIR queue group
  net/ice: add FDIR counter resource init/release
  net/ice: add FDIR counter support
  net/ice: reject duplicate flow for FDIR
  net/ice: add FDIR vxlan tunnel support

Add ice_create_fdir_filter to create a rule. If a flow is matched by
flow director filter, filter rule will be set to HW. For now common
pattern and queue/passthru/drop/mark actions are supported.

This patch add FDIR statistical counter support
and it includes RTE_FLOW count actions support
and query support.

RTE_FLOW count actions support id and shared.
RTE_FLOW query record packet hits by default.

Hi Yahui,

two general comments: 
1.Please make old versions of patches Superseded to facilitate review.
2. the two occurrences of rte_wmb can be removed, a similar patch has been reviewed by Qi. http://patches.dpdk.org/patch/59278/

Off the topic.

This is the patch 60000 in patchwork!
Thanks to everyone contributed!

https://patches.dpdk.org/patch/60000/

The historical numbers from DPDK patchwork:
60000 - Sept. 27, 2019 (248 days) [ 8 months, 5 days / 35 weeks and 3 days ]
50000 - Jan.  22, 2019 (253 days)
40000 - May.  14, 2018 (217 days)
30000 - Oct.   9, 2017 (258 days)
20000 - Jan.  25, 2017 (372 days)
10000 - Jan.  20, 2016 (645 days)
00001 - April 16, 2014


It looks like pace is getting stabilized around ~250 days for 10K patch.

Add ice_create_fdir_filter to create a rule. If a flow is matched by
flow director filter, filter rule will be set to HW. For now common
pattern and queue/passthru/drop/mark actions are supported.

This patch add FDIR statistical counter support
and it includes RTE_FLOW count actions support
and query support.

RTE_FLOW count actions support id and shared.
RTE_FLOW query record packet hits by default.

This patch series adds Flow Director support for Intel Ethernet
Controller E810 series using RTE_FLOW

- Patch 01-02 are FDIR init,teardown and configuration
- Remaining patches are FDIR RTE_FLOW enablement

The patchset depends on:
http://patchwork.dpdk.org/project/dpdk/list/?series=6557
---
v5:
* Add GTPU rule support
* Fix tunnel profile conflict issue
* Update filter counter 

v4:
* Remove rte_wmb.
* Update input set mapping table.
* Remove all created profiles during teardown
* Fix tunnel rule duplication detection failure
* Change function name

v3:
* Get flow id in flexible descriptor
* Add vxlan tunnel rule support

v2:
* Move to flexible descriptor.
* Distinguish tunnel and non-tunnel rule.
* Add uninit function for fdir engine.
* Fix coding style.
* Change patch organization.
* Add release notes.

From: Beilei Xing <beilei.xing@intel.com>

This patch adds a HW FDIR rule to the FDIR HW table
without adding a FDIR filter.

Add ice_create_fdir_filter to create a rule. If a flow is matched by
flow director filter, filter rule will be set to HW. For now common
pattern and queue/passthru/drop/mark actions are supported.

This patch add FDIR statistical counter support
and it includes RTE_FLOW count actions support
and query support.

RTE_FLOW count actions support id and shared.
RTE_FLOW query record packet hits by default.

This patch series adds Flow Director support for Intel Ethernet
Controller E810 series using RTE_FLOW

- Patch 01-02 are FDIR init,teardown and configuration
- Remaining patches are FDIR RTE_FLOW enablement

---
v6:
* Fix build error on different platform

v5:
* Add GTPU rule support
* Fix tunnel profile conflict issue
* Update filter counter 

v4:
* Remove rte_wmb.
* Update input set mapping table.
* Remove all created profiles during teardown
* Fix tunnel rule duplication detection failure
* Change function name

v3:
* Get flow id in flexible descriptor
* Add vxlan tunnel rule support

v2:
* Move to flexible descriptor.
* Distinguish tunnel and non-tunnel rule.
* Add uninit function for fdir engine.
* Fix coding style.
* Change patch organization.
* Add release notes.

Beilei Xing (2):
  net/ice: enable flow director engine
  net/ice: configure HW FDIR rule

Yahui Cao (7):
  net/ice: add FDIR create and destroy
  net/ice: enable FDIR queue group
  net/ice: add FDIR counter resource init/release
  net/ice: add FDIR counter support
  net/ice: reject duplicate flow for FDIR

Add ice_create_fdir_filter to create a rule. If a flow is matched by
flow director filter, filter rule will be set to HW. For now common
pattern and queue/passthru/drop/mark actions are supported.

This patch add FDIR statistical counter support
and it includes RTE_FLOW count actions support
and query support.

RTE_FLOW count actions support id and shared.
RTE_FLOW query record packet hits by default.

This patch series adds Flow Director support for Intel Ethernet
Controller E810 series using RTE_FLOW

- Patch 01-02 are FDIR init,teardown and configuration
- Remaining patches are FDIR RTE_FLOW enablement

---
v7:
* Fix shared library build error

v6:
* Fix build error on different platform

v5:
* Add GTPU rule support
* Fix tunnel profile conflict issue
* Update filter counter 

v4:
* Remove rte_wmb.
* Update input set mapping table.
* Remove all created profiles during teardown
* Fix tunnel rule duplication detection failure
* Change function name

v3:
* Get flow id in flexible descriptor
* Add vxlan tunnel rule support

v2:
* Move to flexible descriptor.
* Distinguish tunnel and non-tunnel rule.
* Add uninit function for fdir engine.
* Fix coding style.
* Change patch organization.
* Add release notes.

This patch adds a HW FDIR rule to the FDIR HW table
without adding a FDIR filter.

Add ice_create_fdir_filter to create a rule. If a flow is matched by
flow director filter, filter rule will be set to HW. For now common
pattern and queue/passthru/drop/mark actions are supported.

This patch add FDIR statistical counter support
and it includes RTE_FLOW count actions support
and query support.

RTE_FLOW count actions support id and shared.
RTE_FLOW query record packet hits by default.
