Hi,
I am testing https://github.com/iqiyi/dpvs in KVM VM running Ubuntu with Intel 82599 SR-IOV VF. got error like: # ./dpvs current thread affinity is set to F EAL: Detected 4 lcore(s) EAL: Probing VFIO support...

So in not VT mode rx_queue defines absolute queue number, and in VT rx_queue defines relative queue number within VF. I can make patch later when I will have free time. Regards, Vladimir " I found no support in DPDK ixgbe VF flow director in ixgbe commit history, could anyone confirm that is the case? if no support, any plan to support it?
