Hey Brian, I believe it fetches it again because the file doesn't match the hash string present in one of the files inside the dpdk directory. At least that was the issue I faced building for Mellanox cards ages ago. You could also specify that it uses an external DPDK source.

The info on the DPDK website says the drivers I have should work fine. Thus, the only issue is adding in the correct manufacturer/device IDs into the init.c file: src/plugins/dpdk/device/init.c I edit the file (one-line change), put it back into the .tar.xz file, put it where it should be being picked up (in build-root or so I believe), and it gets blown away. It always seems to want to pull everything from git regardless of the presence of the right tar.xz file in build-root, pointed to by the vpp-latest symbolic link. I am using "make pkg-rpm" as the command to rebuild things from the main vpp source root (parent of build-root). What am I doing wrong? Where should I be rebuilding this? What command should I use? Or what make target? In what directory? Thanks in advance. Brian P.S. I already spent a lot of time chasing a red herring. Does someone want to explain to me the purpose of the "sed -e s/-/_/" in extras/rpm/Makefile, full line: RELEASE=$(shell echo $(BASENAME) | cut -f3- -d- | sed -e s/-/_/g) It seems really out of place, and leads to lots of difficulty in tracking down the place where something that looks like "foo-bar-blech" becomes "foo-bar_blech", for no obvious reason.
