The kernel has older version of PF than the one released on sf.net. So I'm checking the sf.net release. If the change is limited in DPDK then it is controllable. But now it affects Intel's PF driver, I don't even know how to push the feature to Intel. The driver on sf.net is a read-only repository, isn't it? It would be painful to maintain another branch of 10G PF driver. Could Intel give some advice or hints here? thx & rgds, -Qinglai On Wed, Oct 16, 2013 at 3:58 PM, Thomas Monjalon wrote: > 16/10/2013 14:18, jigsaw : >> Therefore, to add support for multiple queues per VF, we have to at >> least fix the PF driver, then add support in DPDK's VF driver. > > You're right, Linux PF driver have to be updated to properly manage > multiple queues per VF.
