Add flex item as modify field destination.
Add "struct rte_flow_item_flex_handle *flex_handle" into
"struct rte_flow_action_modify_data" as union with existed
"level" member. This new member is dedicated for modifying
flex item.

Add flex item modify field cmdline support. Now user can use
testpmd cli to specify which flex item to be modified, either
source or destination.
Syntax is as below:
modify_field op set dst_type flex_item dst_level 0
dst_offset 16 src_type value src_value 0x123456781020 width 8

In async flow create API, there is only mask information when
creating flow table but flex item handle is required to parse
the HW sample information.
Pass the flex item handle instead of UINT64/32_MAX to mask.

To: matan, viacheslavo, orika, thomas; +Cc: dev, rasland
Support flex item matching in hws and syntax follows
sws exactly.
Flex item should be created in advance and follow current
json mapping logic.

Add flex item as modify field destination.
Add "struct rte_flow_item_flex_handle *flex_handle" into
"struct rte_flow_action_modify_data" as union with existed
"level" member. This new member is dedicated for modifying
flex item.
Add flex item modify field cmdline support. Now user can use
testpmd cli to specify which flex item to be modified, either
source or destination.
Syntax is as below:
modify_field op set dst_type flex_item dst_level 0
dst_offset 16 src_type value src_value 0x123456781020 width 8

In async flow create API, there is only mask information when
creating flow table but flex item handle is required to parse
the HW sample information.
Pass the flex item handle instead of UINT64/32_MAX to mask.

Per newest PRM definition, sample_id stands for 3 parts
of information instead of single uint32_t id: sample_id +
modify_filed_id + format_select_dw.
Also new FW capability bits have been introduces to identify
the new capability.

Support flex item matching in hws and syntax follows
sws exactly.
Flex item should be created in advance and follow current
json mapping logic.

Return unsupported error message when application tries to
modify flex item field.
Validation of packet modifications actions for SW Steering checked
if either source or destination field of MODIFY_FIELD action
was a flex item.
When DEC_TTL action is used, DEC_TTL action does not have any
action configuration and dereferencing source or destination field
is invalid, so validation of source and destination field types
should be moved to MODIFY_FIELD specific validation function, then
field types are validated if and only if action type is MODIFY_FIELD.

If flex item is referenced in async flow either by
pattern template or action template, currently testpmd
complains "flex item has flow references". Flex items should
be flushed after async flow resources cleanup.

Have you tried to generate documentation? If it is a union documentation
it should be /**, not /**<.
In general, it is better to document union from overall
point of view. What is it logically? Do not define union

Currently, 'flex_handle' is documents in rte_flow.rst file " table:: destination/source field definition" as a new row.
From API aspect, when modifying flex item, user should specify the pointer of the flex item instead of ID.
That' why it was added as a union.

See above. Do we need another place to document the union again?

Support flex item matching and modify field in async flow.
Syntax follows sync flow exactly.
v3: enhance format, add flex_handle document.

Add flex item as modify field destination.
Add "struct rte_flow_item_flex_handle *flex_handle" into
"struct rte_flow_action_modify_data" as union with existed
"level" member. This new member is dedicated for modifying
flex item.
Add flex item modify field cmdline support. Now user can use
testpmd cli to specify which flex item to be modified, either
source or destination.
Syntax is as below:
modify_field op set dst_type flex_item dst_level 0
dst_offset 16 src_type value src_value 0x123456781020 width 8

In async flow create API, there is only mask information when
creating flow table but flex item handle is required to parse
the HW sample information.
Pass the flex item handle instead of UINT64/32_MAX to mask.

Per newest PRM definition, sample_id stands for 3 parts
of information instead of single uint32_t id: sample_id +
modify_filed_id + format_select_dw.
Also new FW capability bits have been introduces to identify
the new capability.

Support flex item matching in hws and syntax follows
sws exactly.
Flex item should be created in advance and follow current
json mapping logic.

Return unsupported error message when application tries to
modify flex item field.
Validation of packet modifications actions for SW Steering checked
if either source or destination field of MODIFY_FIELD action
was a flex item.
When DEC_TTL action is used, DEC_TTL action does not have any
action configuration and dereferencing source or destination field
is invalid, so validation of source and destination field types
should be moved to MODIFY_FIELD specific validation function, then
field types are validated if and only if action type is MODIFY_FIELD.

If flex item is referenced in async flow either by
pattern template or action template, currently testpmd
complains "flex item has flow references". Flex items should
be flushed after async flow resources cleanup.

Add flex item as modify field destination.
Add "struct rte_flow_item_flex_handle *flex_handle" into
"struct rte_flow_action_modify_data" as union with existed
"level" member. This new member is dedicated for modifying
flex item.
Add flex item modify field cmdline support. Now user can use
testpmd cli to specify which flex item to be modified, either
source or destination.
Syntax is as below:
modify_field op set dst_type flex_item dst_level 0
dst_offset 16 src_type value src_value 0x123456781020 width 8

In async flow create API, there is only mask information when
creating flow table but flex item handle is required to parse
the HW sample information.
Pass the flex item handle instead of UINT64/32_MAX to mask.

Per newest PRM definition, sample_id stands for 3 parts
of information instead of single uint32_t id: sample_id +
modify_filed_id + format_select_dw.
Also new FW capability bits have been introduces to identify
the new capability.

Return unsupported error message when application tries to
modify flex item field.
Validation of packet modifications actions for SW Steering checked
if either source or destination field of MODIFY_FIELD action
was a flex item.
When DEC_TTL action is used, DEC_TTL action does not have any
action configuration and dereferencing source or destination field
is invalid, so validation of source and destination field types
should be moved to MODIFY_FIELD specific validation function, then
field types are validated if and only if action type is MODIFY_FIELD.

If flex item is referenced in async flow either by
pattern template or action template, currently testpmd
complains "flex item has flow references". Flex items should
be flushed after async flow resources cleanup.

Support flex item matching and modify field in async flow.
Syntax follows sync flow exactly.
v4: split ethdev part.
v3: enhance format, add flex_handle document.
Rongwei Liu (4):
ethdev: add flex item modify field support
app/testpmd: pass flex handle into matching mask
app/testpmd: raw encap with flex item support
app/testpmd: adjust cleanup sequence when quitting

Add flex item as modify field destination.
Add "struct rte_flow_item_flex_handle *flex_handle" into
"struct rte_flow_action_modify_data" as union with existed
"level" member. This new member is dedicated for modifying
flex item.
Add flex item modify field cmdline support. Now user can use
testpmd cli to specify which flex item to be modified, either
source or destination.
Syntax is as below:
modify_field op set dst_type flex_item dst_level 0
dst_offset 16 src_type value src_value 0x123456781020 width 8

In async flow create API, there is only mask information when
creating flow table but flex item handle is required to parse
the HW sample information.
Pass the flex item handle instead of UINT64/32_MAX to mask.

If flex item is referenced in async flow either by
pattern template or action template, currently testpmd
complains "flex item has flow references". Flex items should
be flushed after async flow resources cleanup.

Support flex item matching in hws and syntax follows
sws exactly.
Flex item should be created in advance and follow current
json mapping logic.
