dev_ioctl: add missing NETDEV_CHANGE_TX_QUEUE_LEN event notification
When changing dev tx_queue_len via netlink or net-sysfs, a NETDEV_CHANGE_TX_QUEUE_LEN event notification will be called. But dev_ioctl missed this event notification, which could cause no userspace notification would be sent. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.
