| '1' indicates an error on device activation. Not sure about the 'unknown
| command' case.
Ideally it should be same, inconsistent return codes wouldn't be helpful.
| Linux driver uses VXMNET3_READ_BAR1_REG() which calls readl().

Right.

That is odd. It does not seem right to use uint64_t for 32bit values, and
then return a negative(-1) value.
@Dmitry...?
