00026  * \brief specify a daughterboard and subdevice on a daughterboard.
00027  *
00028  * In the USRP1, there are two sides, A and B.
00029  *
00030  * A daughterboard generally implements a single subdevice, but may in
00031  * general implement any number of subdevices.  At this time, all daughterboards
00032  * with the exception of the Basic Rx and LF Rx implement a single subdevice.
00033  *
00034  * The Basic Rx and LF Rx implement 2 subdevices (soon 3).  Subdevice
00035  * 0 routes input RX-A to the DDC I input and routes a constant zero
00036  * to the DDC Q input.  Similarly, subdevice 1 routes input RX-B to
00037  * the DDC I input and routes a constant zero to the DDC Q
00038  * input.  Subdevice 2 (when implemented) will route RX-A to the DDC I
00039  * input and RX-B to the DDC Q input.
