No strong opinion on moving source code around here... but: We should be careful that the build system leaves the .ko and other files i= n the same place as before as moving the build output may break automated d= eployments of other projects that use DPDK. We've accidentally broken things before, for example moving scripts/ to use= rtools/ broke automation in OpenStack IIRC. > > > There are also some kernel modules in the bsdapp directory. > > > > We can move them as well.
