The code does assume this currently.  The code should check that the net_device 
type = ARPHRD_INFINIBAND.  Without this check, the CMA will simply error out 
later when mapping the returned address to a GID.

I guess the proper thing to return is -ENODEV from ib_translate_addr() if we 
have the wrong device type.  The CMA could then check iWarp devices.
