Table 1.1 from the above 17.08 doc is missing vmxnet3. The vmxnet3 driver 
is missing from 17.05 doc as well 
(http://dpdk.readthedocs.io/en/v17.05/nics/overview.html) but it is 
present in 17.02 
(http://dpdk.readthedocs.io/en/v17.02/nics/overview.html). Not sure if I 
missed something?

Thanks,
Shri
