Thanks, can you please put this into commit log in next version? And even FMAN
is not familiar to me, so even a little more details can help.

For DPDK this is dead code, can it be possible to strip kernel related ones in
the DPDK code? With some kind of OS layer perhaps (that is what Intel does).

I agree that it is more practical to avoid maintenance cost for style issues in
this kind of shared code.
But please at least ensure the style is consistent in the file/module with its
initial style.
