[dpdk-dev] [PATCH] net/mlx5: fix VLAN inner ethernet type on E-Switch

[Viacheslav Ovsiienko <viacheslavo@mellanox.com>]

The TCA_FLOWER_KEY_VLAN_ETH_TYPE should be specified for the E-Switch
Flows with VLAN and L3 pattern items in the Netlink messages. The patch
adds missing flower key to the messages. This patch partially reverts to
the code smashed by http://patches.dpdk.org/patch/47781

Fixes: 251e8d02cf37 ("net/mlx5: add VXLAN to flow translate routine")
