This patch introduces: - VMxnet3 v4 negotiation and, - entirely guest-driven UDP RSS support. VMxnet3 v3 already has UDP RSS support, however it depends on hypervisor provisioning on the VM through ESX specific flags, which are not transparent or known to the guest later on. Vmxnet3 v4 introduces a new API transaction which allows configuring RSS entirely from the guest. This API must be invoked after device shared mem region is initialized. IPv4 ESP RSS (SPI based) is also available, but currently there are no ESP RSS definitions on rte_eth layer to handle that.
