Subject: ixgbe/ixgbevf: Enables TSO for MPLS encapsulated packets
Patch-mainline: v4.13-rc1
Git-commit: 2a20525b26475528dc5a664478db2fea23c57d42
References: bsc#1056657 FATE#322189 bsc#1056653 FATE#322190
This patch advertises TSO & GSO features in netdev->mpls_features.
In ixgbe(vf)_tso() where we set up segmentation offload, the IP
header will be the inner network header when eth_p_mpls() indicates
the Ethernet protocol is MPLS (UC or MC).
