This seems strange. What sort of routing protocol can you build, which
has a NULL receive function? Only static routes. I would perform the
check once in _register(), that there is a receive function, and never
check it again. Save yourself a few cycles. 

There is an LWN article about these ideas. Worth a read. I will post a
link later.
