This is baseband data, which need to be processed by the offload device. 
It is important for know the endianness of this data else the offload 
device will not be able to process it correctly.

The existing files only have data in little-endian format.  In the real 
world, the network data can come in big-endian format, so the drivers 
(running on Little-endian machine) shall be able to pass the big-endian 
data for processing to offload device.
