 Subject: [PATCH] DVB : add option to dump PDU exchanged with CAM in
 dvb_core
 
 Dear all,
 
 Here is a patch for the dvb_core module, you'll find it attached to this
 message.
 
 It's adding a new module integer parameter called cam_dump_pdu that
 can have the following values:
 - 0 (by default): don't dump PDU (do nothing)
 - 1: Dump all PDU written and read on device through the syscall
 functions.
 The PDU are dumped in segments of 16 bytes maximum written in
 hexadecimal.
 - 2: like value 1 but remove the commonly used PDU for polling
 (generating a lot of noise in the logs)
 
 The goal of dumping PDU exchanged with CAM is to help debugging userland
 applications and libraries.

I have to add that the PDU dumped are the TPDU (Transport Protocol Data
Units), the 2nd level of the stack.
The first level of PDU, the LPDU (Link Protocol Data Unit) fragments, are
reassembled by the dvb_core module and are not exposed to the applications.

Anyone interested by this option?

 
 This is my first patch submission, so I may have made some errors
 regarding the submission rules.
 
 Best regards,
 Sebastien.
