With the current libnet version (1.1.*) you need to root rights as
the only output device is either through RAW sockets or link level
sockets.

However, in the "devel" version (libnetng), I have added a PCAP
injection mode, which requires no privilege at all.

Have a look here :

Get the last sources and the README.ng file. You can also view the
sample directory.
