Vinicius Costa Gomes 92f4b6032e taprio: Add support for cycle_time and cycle_time_extension
This allows a cycle-time and a cycle-time-extension to be specified.

Specifying a cycle-time will truncate that cycle, so when that instant
is reached, the cycle will start from its beginning.

A cycle-time-extension may cause the last entry of a cycle, just
before the start of a new schedule (the base-time of the "admin"
schedule) to be extended by at maximum "cycle-time-extension"
nanoseconds. The idea of this feauture, as described by the IEEE
802.1Q, is too avoid too narrow gate states.

Example:

tc qdisc change dev IFACE parent root handle 100 taprio \
	      sched-entry S 0x1 1000000 \
	      sched-entry S 0x0 2000000 \
	      sched-entry S 0x1 3000000 \
	      sched-entry S 0x0 4000000 \
	      cycle-time-extension 100000 \
	      cycle-time 9000000 \
	      base-time 12345678900000000

This is a set of utilities for Linux networking.

How to compile this.
--------------------
1. libdbm

arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines.  Often this is in the db-devel package.

2. make

The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.

3. To make documentation, cd to doc/ directory , then
   look at start of Makefile and set correct values for
   PAGESIZE=a4		, ie: a4 , letter ...	(string)
   PAGESPERPAGE=2	, ie: 1 , 2 ...		(numeric)
   and make there. It assumes, that latex, dvips and psnup
   are in your path.

4. This package includes matching sanitized kernel headers because
   the build environment may not have up to date versions. See Makefile
   if you have special requirements and need to point at different
   kernel include files.
