[Fuego] change vlan id maximum to 4094 for vlan01

[qiutt]

details: for vlan01 in net.features, create a vlan interface in the vlan id range (maximum 4095), 
and then delete the created vlan interface in turn.
but VLAN identifier (VID): a 12-bit field specifying the VLAN to
which the frame belongs. The hexadecimal values of 0x000 and 0xFFF are
reserved. All other values may be used as VLAN identifiers, allowing up
to 4,094 VLANs.
