The subtest sends 33 packets at one time on purpose to see if xsk exitting __xsk_generic_xmit() updates the global consumer of tx queue when reaching the max loop (max_tx_budget, 32 by default). The number 33 can avoid xskq_cons_peek_desc() updates the consumer when it's about to quit sending, to accurately check if the issue that the first patch resolves remains. The new case will not check this issue in zero copy mode.
