The only part of commit d378220c (src/nf-queue.c: cleanup and improve
performance of test program for NF_QUEUE) that actually makes sense is
the increase in receive buffer size. Issuing verdicts for IDs not delivered
to userspace is a wasted effort since the kernel drops packets itself when
netlink message delivery fails. This would actually have been noticed
by a return value of -ENOENT if the result of nfnl_queue_msg_send_verdict()
would have been checked.
