ring: Mark potentially unused parameters as such
The parameters to tpacket_uhdr_vlan_tci() and tpacket_uhdr_vlan_proto() might be unused, depending on the definition of HAVE_TPACKET3 and TP_STATUS_VLAN_TPID_VALID. Thus, mark them with __maybe_unused to prevent -Wunused-parameter warnings. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
