it's not necessary to check if the final result

Offload following modify TTL actions to E-Switch via
TC-Flower driver
- RTE_FLOW_ACTION_TYPE_SET_TTL
- RTE_FLOW_ACTION_TYPE_DEC_TTL
The corresponding IP protocol rte_flow_item_ipv[4|6]
must be present in rte_flow pattern otherwith PMD

I mistakenly put comments on the v1 [1].
Xiaoyu, please refer to that.
Ferruh, he is on vacation. He'll response once he returns.

Can you please rebase on top of latest next-net? I guess Adrien's "flow API
object converter" causing conflict with existing rte_flow patches.

This patch series is for RFC[1] and depends on patch[2]
Patch 1 adds generic TTL rewrite actions to flow API
Patch 2 adds corresponding testpmd commands
Patch 3 implements the offloading logic of E-Switch rules on Mellanox MLX5
[1]: https://patches.dpdk.org/patch/43617/
[2]: https://patches.dpdk.org/patch/46490/
v2:
* fix misspelled issues reported by checkpatch
v3:
* rebased
* changed commit title of patch 3
* added example testpmd command in commit log
* changes in validation

rewrite TTL by decrease or just set it directly
it's not necessary to check if the final result
is zero or not
This is slightly different from the one defined
by openflow and more generic

Offload following modify TTL actions to E-Switch via
TC-Flower driver
- RTE_FLOW_ACTION_TYPE_SET_TTL
- RTE_FLOW_ACTION_TYPE_DEC_TTL
The corresponding IP protocol rte_flow_item_ipv[4|6]
must be present in rte_flow pattern otherwith PMD
return error
The example testpmd commands are:
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7000 / end
actions dec_ttl /
port_id id 1 / end
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7001 / end
actions set_ttl ttl_value 10 /
port_id id 1 / end

This patch series is for RFC[1] and depends on patch[2]
Patch 1 adds generic TTL rewrite actions to flow API
Patch 2 adds corresponding testpmd commands
Patch 3 implements the offloading logic of E-Switch rules on Mellanox MLX5
[1]: https://patches.dpdk.org/patch/43617/
[2]: http://patches.dpdk.org/patch/46621/
v2:
* fix misspelled issues reported by checkpatch
v3:
* rebased
* changed commit title of patch 3
* added example testpmd command in commit log
* changes in validation
v4:
* fix some coding style issues
* use macro of calc pedit keys
* rebased

rewrite TTL by decrease or just set it directly
it's not necessary to check if the final result
is zero or not
This is slightly different from the one defined
by openflow and more generic

Offload following modify TTL actions to E-Switch via
TC-Flower driver
- RTE_FLOW_ACTION_TYPE_SET_TTL
- RTE_FLOW_ACTION_TYPE_DEC_TTL
The corresponding IP protocol rte_flow_item_ipv[4|6]
must be present in rte_flow pattern otherwith PMD
return error
The example testpmd commands are:
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7000 / end
actions dec_ttl /
port_id id 1 / end
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7001 / end
actions set_ttl ttl_value 10 /
port_id id 1 / end

This patch series is for RFC[1] and depends on patch[2]
Patch 1 adds generic TTL rewrite actions to flow API
Patch 2 adds corresponding testpmd commands
Patch 3 implements the offloading logic of E-Switch rules on Mellanox MLX5
[1]: https://patches.dpdk.org/patch/43617/
[2]: http://patches.dpdk.org/patch/46621/
v2:
* fix misspelled issues reported by checkpatch
v3:
* rebased
* changed commit title of patch 3
* added example testpmd command in commit log
* changes in validation
v4:
* fix some coding style issues
* use macro of calc pedit keys
* rebased
v5:
* fix document warning of rte_flow.rst introduced by v4

rewrite TTL by decrease or just set it directly
it's not necessary to check if the final result
is zero or not
This is slightly different from the one defined
by openflow and more generic

RTE_FLOW_ACTION_TYPE_TUNNEL_DECAP,
For maximum flexibility, all actions should be usable on their own on empty
pattern. On the other hand, you can document undefined behavior when
performing some action on traffic that doesn't contain something.
Reason is that invalid traffic may have already been removed by other flow
rules (or whatever happens) before such a rule is reached; it's a user's
responsibility to provide such guarantee.
When parsing an action, a PMD is not supposed to look at the pattern. Action
list should contain all the needed info, otherwise it means the API is badly
defined.
I'm aware the above makes it tough to implement something like
RTE_FLOW_ACTION_TYPE_TUNNEL_DECAP as defined in this series, but that's
unfortunately why I think it must not be defined like that.

Alright, I'will document this as PMD's limitation not API's.

- RTE_FLOW_ACTION_TYPE_SET_TTL
- RTE_FLOW_ACTION_TYPE_DEC_TTL
The corresponding IP protocol rte_flow_item_ipv[4|6]
must be present in rte_flow pattern otherwith PMD
return error
The example testpmd commands are:
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7000 / end
actions dec_ttl /
port_id id 1 / end
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7001 / end
actions set_ttl ttl_value 10 /
port_id id 1 / end

rewrite TTL by decrease or just set it directly
it's not necessary to check if the final result
is zero or not
This is slightly different from the one defined
by openflow and more generic

Offload following modify TTL actions to E-Switch via
TC-Flower driver
- RTE_FLOW_ACTION_TYPE_SET_TTL
- RTE_FLOW_ACTION_TYPE_DEC_TTL
The corresponding IP protocol rte_flow_item_ipv[4|6]
must be present in rte_flow pattern otherwith PMD
return error
The example testpmd commands are:
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7000 / end
actions dec_ttl /
port_id id 1 / end
flow create 0 transfer ingress
pattern eth / ipv4 / udp dst is 7001 / end
actions set_ttl ttl_value 10 /
port_id id 1 / end
