[dpdk-dev] [PATCH v4 03/11] net/mlx5: support L3 VXLAN flow

[Xueming Li]

This patch support L3 VXLAN, no inner L2 header comparing to standard
VXLAN protocol. L3 VXLAN using specific overlay UDP destination port to
discriminate against standard VXLAN, FW has to be configured to support
it:
  sudo mlxconfig -d <device> -y s IP_OVER_VXLAN_EN=1
  sudo mlxconfig -d <device> -y s IP_OVER_VXLAN_PORT=<port>
