[dpdk-dev] vmxnet3 pmd dev restart

[Navakanth M]

Hi

I am using DPDKv1.7.0 running on Vmware Esxi 5.1 and am trying to
reset the port which uses pmd_vmnet3 library functions from below
function calls.
rte_eth_dev_stop
rte_eth_dev_start

Doing this, i face panic while rte_free(ring->buf_info) in
Vmxnet3_cmd_ring_release().
I have gone through following thread but the patch mentioned didn't
help rather it crashed in start function while accessing buf_info in
vmxnet3_post_rx_bufs. I see this buf_info is allocated in queue setup
functions which are called at initialization.
http://thread.gmane.org/gmane.comp.networking.dpdk.devel/4683

I tried not freeing it and then rx packets are not received due to mismatch in
while (rcd->gen == rxq->comp_ring.gen) in vmxnet3_recv_pkts()

To reset the device port, is this the right way what i am doing?
Or do I have to call vmxnet3_dev_tx_queue_setup()
vmxnet3_dev_rx_queue_setup() once stop is called? I have checked
recent patches and threads but did not get much information on this.

Thanks
