* The 'loopback info' is a table (array) of available loopback modes.

* speed or style of loopback implemented), and a key value, used in the
* GET_MODE and SET_MODE commands.
*
* So, a loopback-test program could:
* open the network device
* use the LB_GET_INFO_SIZE ioctl (parameter: &size)
* to find the size of the info array
* allocate some space for the info array
* use the LB_GET_INFO ioctl (parameter: infoptr)
* to get the whole info array
* search the array for a particular type of loopback (e.g. internal),
* or display all the available modes for the user to select one
* use the LB_GET_MODE ioctl (parameter: &oldmode)
* to get the current mode
* use the LB_SET_MODE ioctl (parameter: &newmode)
* to set the new mode
* perform the test(s)
* use the LB_SET_MODE ioctl (parameter: &oldmode)
* to restore the new mode
