The GPL sources are not really separated. The DPDK libraries must be BSD-licensed. > The GPL affected source codes reside in the mlnx_uio/kernel directory. It seems that a large part of the GPL driver was also copied in mlnx_uio/mlnx/. Given that you are dropping a huge GPL codebase (whose you don't own the copyright) in a BSD library, and that you didn't give your real name in the signed-off line, it is NACK.
