This is done through 22``/dev/dvb/adapter?/net?`` device node. The data will be available via 23virtual ``dvb?_?`` network interfaces, and will be controlled/routed via 24the standard ip tools (like ip, route, netstat, ifconfig, etc). 25 26Data types and ioctl definitions are defined via ``linux/dvb/net.h`` 27header. 28 29 30.. _net_fcalls: 31 32Digital TV net Function Calls 33############################# 34 35.. toctree:: 36 :maxdepth: 1 37 38 net-types 39 net-add-if 40 net-remove-if 41 net-get-if 42
