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

[Thomas Monjalon <thomas.monjalon@6wind.com>]

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.
