Userspace fallback is always available, even if `no-fallback` is set 
(which is relevant during startup only). If a packet is not handled by 
the kernel module for whatever reason, it's always automatically passed 
on to the daemon to be handled (except when explicitly instructed to 
drop a packet, e.g. through `strict-source`). In this sense, you get the 
same behaviour as if `table = -1` is used.
