Hi matan:

I have enabled mlx5 hotplug bas= ed on the failsafe pmd:

"--vdev", "net_f= ailsafe0,mac=3D04:e8:92:7d:dd:e4,dev(08:00.0)", "-b", "= 08:00.0"

08:00.0 is mlx5 NIC.=

The app started successfully.

However, I had some problems ve= rifying the hotplug function. Here are the steps:

echo 1 > /sys/bus/pci/device= s/0000:08:00.0/remove

echo 1 > /sys/bus/pci/rescan=

The app had the following error= :

EAL: PCI device 0000:08:00.0 on= NUMA socket 0

EAL: probe driver: = 15b3:1017 net_mlx5

net_mlx5: port 2 cannot get MAC= address, is mlx5_en loaded? (errno: Function not implemented)

net_mlx5: probe of PCI device 0= 000:08:00.0 aborted after encountering an error: No such device<= /span>

EAL: Driver cannot attach the d= evice (08:00.0)

EAL: Failed to attach device on= primary process

net_failsafe: sub_device 0 prob= e failed (No such device)

Look at the code it is through = the ioctl function to obtain the MAC address.

I wonder if there are other con= figurations that have not been done, causing this problem=

Thanks!
