Initialize all supported drivers with rte_pmd_init_all about drv-netif-dpdk

...that's what they use to initialize drivers in their examples that come with the DPDK distribution.

I can't see rte_pmd_init_all() in the dpdk.org release. Am I blind, or is the latest DPDK you're referring to something else than the open source one?

That said, I think init_all would be useful. One could easily do a homegrown approximation. Do you want to send a patch which works against the dpdk.org release?

The one I'm working with is v1.3.1.7, I got it from Intel's web-site: http://www.intel.com/content/www/us/en/intelligent-systems/intel-technology/packet-processing-is-enhanced-with-software-from-intel-dpdk.html
Here is the direct link: http://downloadmirror.intel.com/22777/eng/IntelDPDK.L.1.3.1_7.zip

Unfortunately, I don't have dpdk.org's distribution installed. I looked at their web-site and it seems latest they have is v1.2.3r3.

The API reference for the version I use (http://www.intel.com/content/dam/www/public/us/en/documents/reference-guides/intel-dpdk-api-reference.pdf) does not say when the function was added (which version of the framework).

The framework provides version information though (http://dpdk.org/doc/api/rte__version_8h.html), so it is possible to use init_all if version is at least 1.3.1.7 and fallback to pre-selected driver if not, using some ifdefs.

I'll try it and can send you a patch sometime later if you don't get to it before me.

BTW, aside from the above (I had to switch the dirver init function to init_all), everything worked for me with latest DPDK, Ubuntu 12.04.

I don't have immediate plans to work on initialization -- I feel like the way to init the stack needs a complete overhaul, but I'm not quite sure which way to go in at the moment. You'll most likely get to init before me even if you take your time.

And thanks for the report! It's always nice to hear that software still in its early stages is working for other people too.

I changed it to rte_pmd_init_all().

I think we can safely declare older versions obsolete, so I'm closing this report.

thanks!
