The usage of these macros is spitting out a _lot_ of warnings from sparse when you run it with the -Wbitwise option. Why have your own macros? Just use the cpu_to_le16 and friends in your code, it makes it easier for everyone to understand what you are doing.
And when you do that, care to fix up those warnings?
sparse was new to me... (and hard to find some good docs) I removed the defines and the attached version doesn't produce any warnings.
