[v2,iproute2-next,0/2] tc: support for new MPLS L2 VPN actions

Message

This patch series adds the possibility for TC to tunnel Ethernet frames
over MPLS.

Patch 1 allows adding or removing the Ethernet header.
Patch 2 allows pushing an MPLS LSE before the MAC header.

By combining these actions, it becomes possible to encapsulate an
entire Ethernet frame into MPLS, then add an outer Ethernet header
and send the resulting frame to the next hop.

v2: trivial coding style fix (line wrap).

Guillaume Nault (2):
  m_vlan: add pop_eth and push_eth actions
  m_mpls: add mac_push action
