@ConnorDoyle, we are working on it. @swatisehgal can you provide more details on the design.

Work in progress! Will provide details early next week.

In order to be able to discover SR-IOV capability in the NIC on a node, our current approach is to query the sysfs of the node. There are two SRIOV related files, sysfile /sys/class/net//device/sriov_numvfs and sysfile /sys/class/net//device/sriov_totalvfs that store the configured number of VFs for a specific PF and maximum possible VFs for PFs respectively. These files are NIC vendor agnostic and allow configuration of VFs for specific PFs. The code for SR-IOV discovery would be implemented in Discover() function of networkSource ( which implements FeatureSource ). We will be looking into implementation and incorporating Opaque integer resources into NFD too. Its currently under discussion.

@swatisehgal Thanks for update.

Right now, NFD discovers only binary resources. We will need to discuss with the community before enhancing the scope of NFD.

Sent an email to the dev list to revive the discussion and directed folks to comment in issue #45.
