vpair - virtual E1 interface pair

The virtual E1 interface pair is used to test without any actual E1 hardware. It resembles the concept of a "virtual ethernet pair" (veth pair)
which is found in many containerized Linux applications of today.

The vpair implements two interfaces, each with a configurable number of lines.

Every line N of the first interface is 'virtually looped' to line N of the second interface in the pair.

This way two E1-using applications can talk back-to-back on a single system without any actual E1 interface cards or physical cabling.

In order to use a vpair, you must include the following line in your osmo-e1d.cfg:

virtual-e1-pair 1

Where '1' is the number of lines the virtual interface shall have.
