|
* This routine is the shared memory locked queue MPCI driver routine
|
|
* used to convert the RTEMS's information in a packet from non-native
|
|
* format to processor native format.
|
|
*
|
|
* Input parameters:
|
|
* packet - pointer to a packet
|
|
*
|
|
* Output parameters:
|
|
* *packet - packet in native format
|
|
*
|
|
* NOTE: Message buffers are not manipulated.
|
|
* Endian conversion is currently the only conversion.
