libslirp for Linux made easy peasy - development

 libslirp is a user-mode networking library used by virtual machines,
 containers or various tools. This project wraps the libslirp code in a
 library featuring a clean and simple interface.
 .
 libvdeslirp implements the abstraction of virtual ethernet

 ethernet packets by vdeslirp_send and vdeslirp_recv as if it
 were using a tap interface.
