基于linux内核2.6.9的mpls补丁

MPLS enable iproute2
--------------------

The 'ip' utility that is a part of iproute2 is used to add/delete/modify
the IPv4/IPv6 routing table and interface table.  With this patch it
can add LSPs as the nexthop for an IPv4 route.  This patch also adds
the 'mpls' utility which is the command line utility used to
add/delete/modify NLFE/ILM/XC/Tunnels.

Run it
------

After compiling and installing the MPLS enabled version of iproute, you will
have a new command 'mpls' and a new nexthop option for the 'ip route' command.

Here is a simple example of how to use 'mpls' and the new nexthop
option abailble for 'ip route':

    # mpls nhlfe add key 0 instructions push gen 16 nexthop eth0 ipv4 1.1.1.1
    Key: 0x00000002
    # ip route add 10.0.0.0/8 via 1.1.1.1 spec_nh 0x8847 0x2
    # mpls nhlfe show
    NHLFE entry key 0x00000002 mtu 1496 propagate_ttl
            push gen 16 set wlan0 ipv4 1.1.1.1  (0 bytes, 0 pkts, 0 dropped)
    # ip route show 10.0.0.0/24
    10.0.0.0/24 via 1.1.1.1 dev wlan0 spec_nh 0x8847 0x00000002

** 0x8847 is the ethernet id of unicast MPLS packets
