I would prefer if one can attach the necessary data to the net_buffer 
in some way. In fact, it would be very cheap to have a mechanism that 
"protects" a removed header from being overwritten.
The pointer to the header could be added to the net_buffer structure, 
and the data itself would be freed when the buffer is freed.
