Subject: [PATCH v2 net-next 4/5] net/sched: flower: Dump the ethertype encapsulated in vlan

Currently the encapsulated ethertype is not dumped as it's the same as
TCA_FLOWER_KEY_ETH_TYPE keyvalue. But the dumping result is inconsistent
with input, we add dumping it with TCA_FLOWER_KEY_VLAN_ETH_TYPE.
