[dpdk-dev] [PATCH 1/3] i40e: explicit shared code naming as base driver

The PMD is built on top of the base driver which is provided by Intel
and shouldn't be modified to allow easy batch upgrade from Intel.

The base driver is a "shared code" between many projects. But in DPDK,
the "base driver" naming makes more sense.
