i40e: sriov directory is not found in sysfs

Issue

• Why there is no /sys/class/net/<interface-name>/device/sriov/ directory in RHEL server ?
• While enabling port_mirroring for VFs, /sys/class/net/<interface-name>/device/sriov/ directory doesn't exist.
• We are trying to enable port mirroring from VF to another VF, using echo add 1 > /sys/class/net/<interface-name>/device/sriov/0/ingress_mirror. However, we noticed that there is no such directory in our RHEL 8.5 server.
