Creating a macvtap interface with the liquidio VF driver as lower device causes this alarming message to show up in dmesg:
liquidio_link_ctrl_cmd_completion Unknown cmd 27 That's actually a false alarm because cmd 27 is the value of the macro OCTNET_CMD_SET_UC_LIST which is known. It's a control command sent from host to NIC firmware to set the unicast MAC address list of the macvtap lower device. Make the false alarm go away by adding a case for OCTNET_CMD_SET_UC_LIST in liquidio_link_ctrl_cmd_completion().
