Aaron Stone 1cc3cdf7b5 Always set both SRIOV and ENA when Enhanced Networking is enabled
Set SriovNetSupport to "simple". As of February 2017, this applies to C3, C4,
D2, I2, R3, and M4 (excluding m4.16xlarge).

Set EnaSupport to true. As of February 2017, this applies to C5, I3, P2, R4,
X1, and m4.16xlarge.
