# # MPLS configuration # menuconfig MPLS bool "MultiProtocol Label Switching" default n ---help--- MultiProtocol Label Switching routes packets through logical circuits. Originally conceived as a way of routing packets at hardware speeds (before hardware was capable of routing ipv4 packets), MPLS remains a simple way of making tunnels. If you have not heard of MPLS you probably want to say N here. if MPLS config NET_MPLS_GSO tristate "MPLS: GSO support" help This is helper module to allow segmentation of non-MPLS GSO packets that have had MPLS stack entries pushed onto them and thus become MPLS GSO packets. config MPLS_ROUTING tristate "MPLS: routing support" depends on NET_IP_TUNNEL || NET_IP_TUNNEL=n ---help--- Add support for forwarding of mpls packets. config MPLS_IPTUNNEL tristate "MPLS: IP over MPLS tunnel support" depends on LWTUNNEL && MPLS_ROUTING ---help--- mpls ip tunnel support. endif # MPLS
