DVB net Function Calls
ioctl NET_ADD_IF — Creates a new network interface for a given Packet ID.
ioctl NET_REMOVE_IF — Removes a network interface.
ioctl NET_GET_IFRead the configuration data of an interface created via NET_ADD_IF.

The DVB net device controls the mapping of data packages that are part of a transport stream to be mapped into a virtual network interface, visible through the standard Linux network protocol stack.

Currently, two encapsulations are supported:

In order to create the Linux virtual network interfaces, an application needs to tell to the Kernel what are the PIDs and the encapsulation types that are present on the transport stream. This is done through /dev/dvb/adapter?/net? device node. The data will be available via virtual dvb?_? network interfaces, and will be controlled/routed via the standard ip tools (like ip, route, netstat, ifconfig, etc).

Data types and and ioctl definitions are defined via linux/dvb/net.h header.
