[dpdk-dev] [PATCH] eal: Initial implementation of PQoS EAL extension

[Kantecki, Tomasz]

> EAL should not depend on the PQoS library.
> Please could you hook the command line parsing and help to add these new
> options from outside?

Thanks for the feedback - we heard about dependency problem from a few sources.
 
> The command line options may be convenient in some cases but not
> straightforward for some applications.
> >From now, the runtime options must be also configurable with an API.
> Please consider a clean configuration API first in the library.
> Then it can be hooked in the EAL command line.
> A thought: should we move the EAL command line in a separate library with a
> hook API?

Thanks for the suggestion and the feedback.

Off the mail list, we received feedback that extending EAL commands is not an option due to Intel Architecture nature of CAT.
Consequently, we changed direction when working on V2 PQoS patches in roder to: 
- reduce DPDK PQoS code print and reuse existing open source code
- remove IA specific options from EAL

Current V2 patch, yet to be shared on the mail-list in a few days, implements a sample code (reuse of skeleton) that links against existing 01.org PQoS library. This eliminates need for code included in V1 librte_pqos patch.
The same sample code implements a C module that parses application specific part of the command line with CAT configuration options (same format as V1 EAL command). The module is easy to re-use in other applications as needed.
In the future, if there is a need to change this C module into a regular DPDK library then we'll be happy to do so.

Are you OK with concept behind V2 PQoS patch as described above?

Thanks,
Tomasz
