Please try to avoid introducing more gotos.
If init code below is poll mode specific, let's move it int a separate function.
Then we can have something like:
If (evt_rsrc->enabled) {
...
ret = l3fwd_event_resource_setup(...);
l3fwd_event_service_setup();
...
} else
ret = l3fwd_poll_resource_setup(...);
...
