Merge branch 'tc-etf' into iproute2-next

Merge branch 'tc-etf' into iproute2-next

Jesus Sanchez-Palencia  says:

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

fixes since v3:
 - Add support for clock names with the "CLOCK_" prefix;
 - Print clock name on print_opt();
 - Use strcasecmp() instead of strncasecmp().

The ETF (earliest txtime first) qdisc was recently merged into net-next
[1], so this patchset adds support for it through the tc command line
tool.

An initial man page is also provided.

The first commit in this series is adding an updated version of
include/uapi/linux/pkt_sched.h and is not meant to be merged. It's
provided here just as a convenience for those who want to easily build
this patchset.
