<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.
