<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.
