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

Message

Guillaume Nault Oct. 13, 2020, 2:32 p.m. UTC

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.

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