> Subject: [PATCH v4 1/2] ethdev: introduce generic copy rte flow action
> 
> Implement a generic copy flow API to allow copying of an arbitrary
> header field (as well as mark, metadata or tag) to another field.
> 
> This generic copy mechanism removes the necessity to implement a
> separate RTE Flow action every time we need to modify a new packet
> field in the future. A user-provided value can be used from a
> specified tag/metadata/mark or directly copied from another packet field.
> 
> The field ID is used to specify the desired source/destination packet
> field in order to simplify the API for various encapsulation models.
> Specifying the packet field ID with the needed encapsulation level
> is able to quickly get a packet field for any inner packet header.
> 
> Alternatively, the special ID (ITEM_START) can be used to point to the
> very beginning of a packet. This ID in conjunction with the offset
> parameter provides great flexibility to copy/modify any part of a packet
>  as needed.
> 
> The number of bits to copy as well as the offset to start from can
> be specified to allow a partial copy or dividing a big packet field
> into multiple small fields (let's say copying 128 bits of IPv6 to 4 tags).
