vmxnet3: add logging support to the control plane [VPP-1470]
There are different flavors of vmxnet3 device, esxi server, vm fusion, vmware workstation, and vmware player, that we need to communicate with. Each of them also has different versions. We really need the control plane logging to debug when things don't work as expected. Change-Id: I53c23cf10958bfbc06abb1c252d368003563cd04 Signed-off-by: Steven <sluong@cisco.com>
