Similar definitions already exist in enum gelic_lv1_ether_port_status,
to be used with the GELIC_LV1_GET_ETH_PORT_STATUS command.

>From looking at the symmetry between GELIC_LV1_SET_NEGOTIATION_MODE and
GELIC_LV1_GET_ETH_PORT_STATUS, you can just use the existing
GELIC_LV1_VLAN_TX_ETHERNET definition.

So you don't need any new definitions at all, just the knowledge you can use
GELIC_LV1_SET_NEGOTIATION_MODE to set what GELIC_LV1_GET_ETH_PORT_STATUS
returns?
