When using skmsg redirect, the msg is queued in psock->ingress_msg, and the application calling SIOCINQ ioctl will return a readable length of 0, and we cannot track the data length of ingress_msg from the ss tool. In this patch set, we added the data length in ingress_msg to the SIOCINQ ioctl and the rx_queue of tcp_diag.
