Well, other than the obvious checkpatch.pl warnings waiting to trigger
("if" is not a function; put a space before the paren) and what I'd call
missing parens around the "flags & ...", those are *not* errors.  No
wonder you thought this would cause too many messages!!

Just make those be dev_dbg() calls instead.  The strongest message level
you can argue for there would be KERN_NOTICE, "normal but significant";
except it's not especially significant.  Filtering by netif_msg_probe()
may be a good idea too; that's normally enabled in this framework.

p.s. Before these get submitted, *all* of them need to pass "checkpatch.pl".
  Ideally, "checkpatch.pl --strict" ...
