Merge branch 'mpls_tc'
Simon Wunderlich says: ==================== this series contains a header file proposal for MPLS labels. These labels do not seem to be properly defined in the kernel so far. We are developing a wired/wireless 802.21/MPLS switch and need to check the MPLS labels to use the traffic control info for transmissions over 802.11 networks. Changes to third version: * rename mpls_label_stack to mpls_label (thanks Neil) * fix over-indendented closing brac (thanks Sergei) * add Johannes' Ack ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
