Hi Jesse, Hi Pravin, Hi All, This patchset makes use of a whitelist to only allow mpls_push actions to be applied to packets with an ethertype where the tag order is well defined and implemented. This avoids the problem of where an MPLS LSE should be added in relation to a VLAN or similar tag. The list of allowed ethertypes is currently: - ETH_P_IP (0x0800) - ETH_P_ARP (0x0806) - ETH_P_RARP (0x0835) - ETH_P_IPV6 (0x86DD) - ETH_P_MPLS_UC (0x8847) - ETH_P_MPLS_MC (0x8847) I have updated this patch since v2.56 to account for the new sample action which does not have side effects. This has allowed complex verification code in this patch to be replaced with something significantly simpler and smaller.
