[dpdk-dev] [PATCH] ixgbe: query assignment of queues to VF

[jigsaw]

Hi Thomas,

>>Please, keep us informed about the needed PF patch.

First of all, where and how should I post the patch to PF driver?
And secondly I have only 82599, so I cannot run test for 82598 and
X540. Is it possible that you could test on different NIC?

thx &
rgds,
