[dpdk-dev] SR-IOV: dpdk16.07 on guest and ixgbe 3.19.1 on host - will that be a problem ? (requested invalid api version)

[Gopakumar Choorakkot Edakkunni]

I see the below message "requested invalid api version" on host ? Will that
be an issue or is it benign ? Should I upgrade the host ixgbe to a later
version ?

On the host:

*[69576.199458] ixgbe 0000:88:00.1 p4p2: VF 2 requested invalid api version
