Subject: Verificacion de interfaces usando handle_timer().
X-Git-Url: https://git.llucax.com/software/pymin.git/commitdiff_plain/0052c50443c26499dee9ae085d138c237ebe25d8?ds=sidebyside;hp=74b9275a8854636e54e1cbdf7f2cef9d4bc82248

Verificacion de interfaces usando handle_timer().

En util.py se corrige get_network_devices para que
levante los link/ppp.
En ip/__init__.py se agrega refresh_devices para que
a travez del handle_timer se puedan agregar los devices
que se registran a travez del commando ppp y tambien
se borren los devices caidos.
