Add nexthop subcommand to ip. Implement basic commands for creating,
deleting and dumping nexthop objects. Syntax follows 'nexthop' syntax
from existing 'ip route' command.
Examples:
1. Single path
$ ip nexthop add id 1 via 10.99.1.2 dev veth1
$ ip nexthop ls
id 1 via 10.99.1.2 src 10.99.1.1 dev veth1 scope link
2. ECMP
$ ip nexthop add id 2 via 10.99.3.2 dev veth3
$ ip nexthop add id 1001 group 1/2
--> creates a nexthop group with 2 component nexthops:
id 1 and id 2 both the same weight
$ ip nexthop ls
id 1 via 10.99.1.2 src 10.99.1.1 dev veth1 scope link
id 2 via 10.99.3.2 src 10.99.3.1 dev veth3 scope link
id 1001 group 1/2
3. Weighted multipath
$ ip nexthop add id 1002 group 1,10/2,20
--> creates a nexthop group with 2 component nexthops:
id 1 with a weight of 10 and id 2 with a weight of 20
$ ip nexthop ls
id 1 via 10.99.1.2 src 10.99.1.1 dev veth1 scope link
id 2 via 10.99.3.2 src 10.99.3.1 dev veth3 scope link
id 1001 group 1/2
id 1002 group 1,10/2,20

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.
