Hello,

it looks like this revision breaks compilation:

g++: error: ./../libnetlink/lib/libnetlink.a: No such file or directory
g++: error: ./../libnetlink/lib/libutil.a: No such file or directory

It's still missing the code to build the libnetlink directory. Just cd
libnetlink && make. Or you can add it to the build process, but I just
wanted it to build so I could test it.

I don't understand the reason of linking nping against libnetlink like
this. Am I missing something?

Weilin is testing an alternative method of getting the routing table
using libnetlink.

Oops, I see what you mean now. I forgot that nping is an external in
Weilin's branch, so my commit modified the trunk version. I'll fix it.

David Fifield
