Eric Joyner c19c7afee3 ixgbe(4): Convert driver to use iflib 
Initial update to the ixgbe PF and VF drivers to support the iflib interface.

The PF driver version is bumped to 4.0.0, and the VF driver version is bumped to 2.0.0.

Special thanks to sbruno@ for the support in helping make this conversion happen.
