Building iproute2 in parallel might hit the race failure:
	emp_ematch.l:2:30: fatal error: emp_ematch.yacc.h:
		No such file or directory
	make[1]: *** [emp_ematch.lex.o] Error 1

This is because we currently allow the yacc/lex files to generate and
compile in parallel.  So add a simple dependency to make sure yacc has
finished before we attempt to compile the lex output.

Alternative fix to problem reported by: Bin Li
The issue is came from https://bugzilla.novell.com/show_bug.cgi?id=681952.

In any previous version (since suse ... 10.0?), ip addr add always returned
the error code 2 in case the ip address is already set on the interface:

    inet 172.16.2.3/24 brd 172.16.2.255 scope global bond0
RTNETLINK answers: File exists
2

On 11.4, it returns the exit code 254:

    inet 172.16.1.1/24 brd 172.16.1.255 scope global eth0
RTNETLINK answers: File exists
254

This of course causes ifup to return an error in this quite common case..

When changing ip6ip6 parameters (ip -6 tun change), ip passes zeroed
struct ip6_tnl_parm to the kernel. The kernel then tries to change all of
the tunnel parameters to the passed values, including zeroing of local and
remote address. This fails (-EEXIST in net/ipv6/ip6_tunnel.c:ip6_tnl_ioctl).

For other tunnel types, ip fetches the current parameters first and applies
the required changes on top of them. This patch applies the same code as in
ip/iptunnel.c to ip/ip6tunnel.c.

$ ip route monitor
Command "monitor" is unknown, try "ip route help".

(I guess what was really intended is "ip monitor route", so just remove
the argument from the help output.)

The "ip monitor" command does properly decode the "preferred" and
"valid" lifetime records in router advertisements from netlink
