[dpdk-dev] [RFC 17.08] Flow classification library

[Ferruh Yigit]

DPDK works with packets, but some network administration tools works based on
flow information.

This library is suggested to provide helper APIs to convert packet based
information to the flow records. Library header file has more comments on
how library works and provided APIs.

Packets to flow conversion will cause performance drop, that is why this
conversion can be enabled and disabled dynamically by application.

Initial implementation in mind is to provide support for IPFIX metering process
but library planned to be as generic as possible. And flow information provided
by this library is missing to implement full IPFIX features, but this is planned
to be initial step.

It is possible to define flow with various flow keys, but currently only one
type of flow defined in the library, which is more generic, and it offloads
fine grained flow analysis to the application. Library enables expanding for
other flow types.

It will be more beneficial to shape this library to cover more use cases, please
feel free to comment on possible other use case and desired functionalities.

Thanks,
ferruh
