This is the updated "menuconfig" tree for enabling MPLS on a 2.6.23.14 kernel
Networking --->
Networking options --->
<M> Multiprotocol Label Switching
<M> MPLS: Virtual tunnel interface
[*] TCP/IP networking
<M> IP: MPLS support
<*> The IPv6 protocol
<M> IPv6: MPLS support
<*> 802.1d Ethernet Bridging
<M> Bridge: MPLS support
[*] Network packet filtering framework (Netfilter) --->
Core Netfilter Configuration --->
<M> "mpls" target support
Bridge: Netfilter Configuration --->
<*> Ethernet Bridge tables (ebtables) support (NEW)
<M> ebt: MPLS target support
