thanks for your patch. This function is used in a several performance critical
code paths (i.e. packet forwarding).
Are we sure we are not losing in performance here?
Is this a common case?
If yes, then we can inline this part only.
Unfortunately not: this case is rather rare at runtime.
These hash tables are initialized when the batman virtual interface is created
and should be freed only upon interface shutdown.
(actually I believe this might be a good candidate for an unlikely())
