I think for traditional reasons, code in net/* tends to use ntohs()
while code in drivers/* tends to use be16_to_cpu().
In drivers/net/* the two are used roughly the same, though I guess
one could make the argument that be16_to_cpu() would be
more appropriate for data structures exchanged with hardware
while ntohs() makes sense on data structures sent over the
network.
