[PATCH] [dvb-apps] dvbnet

[Stéphane Esté-Gracias <sestegra@xxxxxxx>]

	Hello,

Regarding to previous dvbnet tool retrieve from 
http://www.linuxtv.org/download/dvb/linuxtv-dvb-1.1.1.tar.bz2 tarball, dvbnet 
in actual Mercurial repository doesn't correctly report interface number when 
adding new interface.

See attached patch to fix it.

	Regards,

	Stephane Este-Gracias
