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
====================
