This is done through22``/dev/dvb/adapter?/net?`` device node. The data will be available via23virtual ``dvb?_?`` network interfaces, and will be controlled/routed via24the 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 Calls33#############################34 35.. toctree::36 :maxdepth: 137 38 net-types39 net-add-if40 net-remove-if41 net-get-if42
