Change the PCI enumeration API to individual functions per device type so that only the drivers that are actually in use get linked into the final executable. All of the common code is still shared internally in the env_dpdk library. Change-Id: I2ba83afe59202a510f999a0674e23e60b6581221 Signed-off-by: Daniel Verkamp <daniel.verkamp@intel.com>
