vpp# create sub-interfaces VirtualFunctionEthernet0/5/0 239
create sub-interfaces: rte_eth_dev_set_vlan_offload[0]: err -95

Getting the following error while trying to create sub-interface on a SR-IOV virtual function on a Intel Ethernet controller.
Could you kindly let me know what might be the issue here ?


But, on VIRT-IO this is working.
