[dpdk-dev] [PATCH] ethdev: support action with any config object type

[dpdk-dev] [PATCH] ethdev: support action with any config object type

[Dekel Peled]

In current implementation, an action which requires parameters
must accept them enclosed in a structure.
Some actions require a single, trivial type parameter, but it still
must be enclosed in a structure.
This obligation results in multiple, action-specific structures, each
containing a single trivial type parameter.

This patch introduces a new approach, allowing an action configuration
object of any type, trivial or a structure.

This patch introduces, in test-pmd, a new macro ARG_ENTRY_HTON, to
allow using a single argument, not enclosed in a structure.

The term "object" confuses me a bit, but I'm not a native speaker
so it could be just my wrong association. I'd prefer
"configuration data".

In previous version I wrote just "action configuration", and changed to "action configuration object" per Adrien's suggestion. I think it is better, but if it causes confusion maybe it should be changed.

Adrien, what do you think? Does "configuration data" carry the correct meaning?

Well I'm no native speaker either but "object" is the term used in the C
standard with a well-defined meaning [1] and encompasses everything
(integers, floats, structures, unions, functions, pointers, arrays):

 "region of data storage in the execution environment, the contents of which
  can represent values"

I think it's a bit less vague than "data" because whenever objects are
mentioned in the standard, they always have a type. There's no such thing as
a C object without one, and rte_flow puts a lot of emphasis on documenting
them.

 int foo;
 struct { ... } foo;
 double foo;
 char foo[];
 void *foo;
 
Whatever the type, would you refer to "foo" itself as an "object" or as
"data"?

Unrelated, but you must remove ARG_ENTRY_HTON from this patch since there's
no testpmd change in there that requires it. There's no tolerance for dead
code in testpmd as it doesn't expose an API.

Thanks.

Adrien, thanks a lot. Now "object" looks OK and better than "data".

OK, I'll remove it from this patch and add it to the relevant series.

[dpdk-dev] [PATCH v2] ethdev: support action with any config object type

[Dekel Peled]

In current implementation, an action which requires parameters
must accept them enclosed in a structure.
Some actions require a single, trivial type parameter, but it still
must be enclosed in a structure.
This obligation results in multiple, action-specific structures, each
containing a single trivial type parameter.

This patch introduces a new approach, allowing an action configuration
object of any type, trivial or a structure.
