Subject: [PATCH 118/122] net/hns3: fix a segfault from secondary process
If a hns3 device in the secondary process is attached to do probing
operation, 'rx_queues' and 'tx_queues' in dev->data are null in
eth_dev_fp_ops_setup when calling rte_eth_dev_probing_finish. The primary
process calls dev_start to re-setup their fp_ops. But the secondary process
can't call dev_start and has no chance to do it. If the application sends
and receives packets at this time, a segfault will occur. So this patch
uses the MP communication of the PMD to update the fp_ops of the device in
the secondary process.
