when use crypto vdev in one group primary/secondary processes, when one process up the crypto vdev , if anther dpdk process startup with same dpdk crypto vdev paramters, that will lead to the up vdev started flag set to 0.

from the code, if we want to use the vdev in secondary process , it must be create in primary dpdk process first,and the secondary process which want use the crypto vdev need startup with same dpdk vdev parameters(--vdev).but when one dpdk process start after the crypto vdev up in one process , the vdev started flag will reset to 0. this seem not an expected result,this will broke the active cryptodev using.

test step:

         1: create one crypto vdev in primary dpdk process and then configured and start the crypto vdev . 
         2: startup secondary dpdk process with same crypto vdev parameters(crypto vdev will create in rte_eal_init())

         
        expected result: crypto vdev stats normal in first process  
        actual result:  crypto vdev dev_started set to 0

same issue with up crypto vdev in one secondary process and startup other secondary process with same crypto parameters

this issue will result in different dpdk process can configured and start crypto vdev independently in such scenario, it seem not an expected result. 

from the code we can see 
rte_cryptodev_pmd_allocate {
..............

if (cryptodev->data == NULL) {
		struct rte_cryptodev_data *cryptodev_data =
				cryptodev_globals.data[dev_id];

		int retval = rte_cryptodev_data_alloc(dev_id, &cryptodev_data,
				socket_id);

		cryptodev->data = cryptodev_data;

...............................	

		cryptodev->data->dev_id = dev_id;
		cryptodev->data->socket_id = socket_id;
		cryptodev->data->dev_started = 0;  

		cryptodev->attached = RTE_CRYPTODEV_ATTACHED;

		cryptodev_globals.nb_devs++;
	}
....................
}

in this function "cryptodev->data->dev_started = 0;" will executed in all dpdk process which config with same dpdk crypto vdev, it's better add some condition to set to zero, such as if the dev_started set to 1,dev_started not set here.


would you please help to check and fixed it?


thanks
