=========
`` fd ``

DESCRIPTION
2016-07-05 10:37:31 -03:00
===========
The NET_ADD_IF ioctl system call selects the Packet ID (PID) that
contains a TCP/IP traffic, the type of encapsulation to be used (MPE or
ULE) and the interface number for the new interface to be created. When
the system call successfully returns, a new virtual network interface is
created.
The struct :ref: `dvb_net_if <dvb-net-if>` ::ifnum field will be
filled with the number of the created interface.
