And they require DPDK_*_PATH variables to be set to point at these scripts locally. For new contributors this can be tedious since they will have to clone the whole linux sources just to have simple perl scripts. Update checkpatches.sh and get-maintainer.sh to have them download the upstream scripts if they are not found locally. Store the downloaded scripts in the .git/ folder so that they are found for future runs. If either DPDK_CHECKPATCH_PATH or DPDK_GETMAINTAINER_PATH are set, they will be used in priority.
