2007-05-15- apply hunk that fixes an issue with (wrong?) dependencies. Initial notes were:Bernhard Reutner-Fischer
There is something wrong in the new buildsys: If one selects ip and has e.g. rule or route unset, ip still wants to build those. This fails (correctly) since rtnl_rttable_n2a and rtnl_rtrealm_n2a aren't available if they were turned off. TODO: Talk to vda about this

2007-04-11style fixes, no code changes.Denis Vlasenko
2007-04-11- set the scope properly. Thanks to Jean Wolter, who wrote:Bernhard Reutner-Fischer
busybox ip and the original ip utility behave differently when setting the following route (verified with ip route show using the original ip utility): ip route add 10.0.0.138 dev eth0 Result for busybox ip: # ip route add 10.0.0.138 dev eth0 # /usr/local/bin/ip route show 10.0.0.138 dev eth0 Result for ip: # /usr/local/bin/ip route add 10.0.0.138 dev eth0 # /usr/local/bin/ip route show 10.0.0.138 dev eth0 scope link A following "ip route add default via 10.0.0.138" fails for busybox ip, since the kernel can not find a route to 10.0.0.138 (it replies with Network is unreachable). The reasons seems to be that the original ip utility explicitly sets the scope after parsing all parameters. This is missing in busybox, the attached patch fixes this. I took this from the original iproute sources and removed some variables, which are not needed for busybox.
