Now then, this multi-segment not being supported in vmxnet3 driver is a big= party-pooper for me. Unfortunately in my usecase, I do indeed make heavy u= se of multisegment buffers for sending out the data, so my usecase has fail= ed and I will have to fix that. Also, can you please adivse how much is the max data rates you have been ab= le to achieve with one vmxnet3 10G port. Thanks a lot for the advice once again.
