[PATCH net-next 0/8] iproute2: MPLS support (now with af_bit_len)

[ebiederm@xmission.com (Eric W. Biederman)]

This set of changes  adds support for nexthops in different
address families, with the new netlink RTA_VIA option.

Support is added for routes that change the destination address (as MPLS
does) with the RTA_NEWDST attribute.

Support for MPLS addresses is added (for multiple labels I
had to make up the syntax I used label/label/label as it fits in
well with addresses that don't have a space in them).

Support for these options is merged into David's net-next kernel
tree, and the meaning of the options is unlikely to change in any
significant way before this code merges upstream.

The documentation has been updated to report that the new options
are present and to report roughly what they do.  This includes
ip --help and the man pages.
