Any particular reason you are removing the inline hint here?
It's recommended in networking to avoid using the inline keyword unless someone actually checked the compiler output and found the compiler is being stupid. I don't know the full history of this recommendation tho.
Ah thanks, didn't know that. IIRC there was no particular reason. Probably because the majority of the functions in that header are static inlines.
Doing it like this will add an extra function call for every packet (assuming the compiler decided to inline the previous version)
Should be fine, tiny static function with one caller, I'd bet it's always inlined, even with -Os.
Well it's compilers -- I wouldn't bet, but fair enough
