Cleaning up existing code is best done as part of a series that is
otherwise touching the code; doing it in isolation makes 'git blame'
attribute the wrong author for no good reason.

  Ah, okay. I noticed it while patching 'net_checksum_calculate' routine. 
Should have sent both together.

  Okay.

Thank you.
