ETH_GSTRING_LEN 32 That includes the \0 at the end. So the max length of the key name must is 31. But the length of the prefix "rx_queue_0_" is 11. If the queue num is larger than 10, the length of the prefix is 12. So the key name max is 19. That is too short. We will introduce some keys such as "gso_packets_coalesced". So we should change the prefix to "rx0_".
