<title>DVB Network API</title>
<para>The DVB net device enables feeding of MPE (multi protocol encapsulation) packets
received via DVB into the Linux network protocol stack, e.g. for internet via satellite
applications. It can be accessed through <emphasis role="tt">/dev/dvb/adapter0/net0</emphasis>. Data types and
and ioctl definitions can be accessed by including <emphasis role="tt">linux/dvb/net.h</emphasis> in your
application.
