Currently the vmxnet3 driver has a minimum MTU value of 60. Which
goes against the RFC791 spec which specifies it at 68.
Setting MTU to values between 60 <= MTU <= 67 causes the network
interface to lose its IP, and it fails to restart.
This sets the minimum value to ETH_MIN_MTU (68) which is compatible
with is according to spec.
