Unless you set the DPDK_DOWNLOAD_DIR environment variable, VPP will keep using
the source downloaded in its default location.
Within the vpp repository, at the top-level directory you find a dpdk folder;
try to look at the Makefile in there to understand the logic. Bottom-line: you
need to specify (via the DPDK_DOWNLOAD_DIR) the location where the DPDK
tarball/source code lives if you are trying to use "your own" modified version
of DPDK...
