mlx_pf0vf0  is representor device created after entring switchdev mode? and eth0 in vm is the binded mlx5 VF?

Can you run this command:

sudo grep -ri "" /sys/class/net/*/phys_* 2>/dev/null

example:
/sys/class/net/ens1f0_0/phys_port_name:pf0vf0
/sys/class/net/ens1f0_0/phys_switch_id:b828a50003078a24
/sys/class/net/ens1f0_1/phys_port_name:pf0vf1
/sys/class/net/ens1f0_1/phys_switch_id:b828a50003078a24
/sys/class/net/ens1f0/phys_port_name:p0
/sys/class/net/ens1f0/phys_switch_id:b828a50003078a24

and
sudo ls /sys/class/net/*/device/virtfn*/net

example:
/sys/class/net/ens1f0/device/virtfn0/net:
ens1f2

/sys/class/net/ens1f0/device/virtfn1/net:
ens1f3

and even

lspci | grep -i mellanox ; ls -l /sys/class/net
