Does the mlx5 NIC support reloading

[jinag]

Hi 
I am verifying the reload function of the mlx5 nic based on dpdk 19.11:
echo 1 > /sys/bus/pci/devices/$pci_address/remove
echo 1 > /sys/bus/pci/rescan
rte_bus_probe();  
rte_eth_dev_stop(); 
rte_eth_dev_start(); 
    net_mlx5: port 0 TX queue 0 CQ creation failure
    net_mlx5: port 0 TX queue allocation failed: cannot allocate memory
The nic cannot be reinitialized.


I am not sure if the above operation is correct. Could you please tell me if 
the mlx5 nic supports reloading(for example, the network card is down during 
normal  operation) and which dpdk functions need to be called.


Thanks!
