Introduce a new stress test to check for race conditions in the nfnetlink_queue subsystem, where an entry is freed while another CPU is concurrently walking the global rhashtable. To trigger this, `nf_queue.c` is extended with two new flags: * -O (out-of-order): Buffers packet IDs and flushes them in reverse. * -b (bogus verdicts): Floods the kernel with non-existent packet IDs. The bogus verdict loop forces the kernel's lookup function to perform full rhashtable bucket traversals (-ENOENT). Combined with reverse-order flushing and heavy parallel UDP/ping flooding across 8 queues, this puts the nfnetlink_queue code under pressure. Joint work with Florian Westphal.
