Please enable this option when you configure your kernel, using 'make menuconfig'.
Networking support --> Networking options --> RPS

Because 'struct netdev_queue' has the member 'kobj' only when CONFIG_RPS is defined.
So does 'queues_kset' in 'struct net_device'.

You can find the definition in 'include/linux/netdevice.h'.

struct net_device {
...
#ifdef CONFIG_RPS
    struct kset     *queues_kset;
    struct netdev_rx_queue  *_rx;
    /* Number of RX queues allocated at register_netdev() time */
    unsigned int        num_rx_queues;
    /* Number of RX queues currently active in device */
    unsigned int        real_num_rx_queues;
#ifdef CONFIG_RFS_ACCEL
    /* CPU reverse-mapping for RX completion interrupts, indexed by RX queue number. Assigned by driver.
     * This must only be set if the ndo_rx_flow_steer operation is defined. */
    struct cpu_rmap     *rx_cpu_rmap;
#endif
#endif
...
};
...
struct netdev_queue {
...
#ifdef CONFIG_RPS
    struct kobject      kobj;
#endif

Have a good day!
