It is widely used, but had become unmaintained at packetfactory.net, and it's

This version was forked from the 1.1.3 release candidate, then bug fixed,
actively maintained, and rereleased.

A C library for portable packet creation and injection.
Libnet is an API to help with the construction and handling of network
packets. It provides a portable framework for low-level network
packet writing and handling (use libnet in conjunction with libpcap and
you can write some really cool stuff). Libnet includes packet creation
at the IP layer and at the link layer as well as a host of supplementary
and complementary functionality. Libnet is very handy with which to
write network tools and network test code. See the manpage and sample
test code for more detailed information.
Your old code (circa libnet-1.0.x) WILL NOT WORK with libnet-1.1.x.
