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 v2.55 so that: * The MPLS ethertypes are included in the whitelist of ethertypes that allow mpls_push actions. * It once again applies on top of the master branch Simon Horman (1): datapath: Add basic MPLS support to kernel OPENFLOW-1.1+ | 4 - datapath/Modules.mk | 1 + datapath/actions.c | 119 +++++++++- datapath/datapath.c | 4 +- datapath/flow.c | 29 +++ datapath/flow.h | 17 +- datapath/flow_netlink.c | 298 ++++++++++++++++++++++-- datapath/flow_netlink.h | 2 +- datapath/linux/compat/gso.c | 70 +++++- datapath/linux/compat/gso.h | 41 +++- datapath/linux/compat/include/linux/netdevice.h | 6 +- datapath/linux/compat/netdevice.c | 10 +- datapath/mpls.h | 15 ++ include/linux/openvswitch.h | 9 +- 14 files changed, 568 insertions(+), 57 deletions(-) create mode 100644 datapath/mpls.h -- 1.8.4 _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
