[dpdk-dev] [PATCH v3 1/2] mbuf: introduce new Tx offload flag for MPLS-in-UDP

[Rasesh Mody <rasesh.mody@cavium.com>]

From: Harish Patil <harish.patil@cavium.com>

Some PMDs need to know the tunnel type in order to handle advance TX
features. This patch adds a new TX offload flag for MPLS-in-UDP packets.
