Hi Michael,

Pretty much all of usrp_basic.h as well as usrp_standard.h is wrapped
by gr-usrp/src/usrp1.i.  The usrp specific classes that derive from
gr_block are usrp1_source_base.h and usrp1_sink_base.h.

I recall Matt mentioning that to read the RSSI you use one of the aux
adcs.  These are already wrapped.

See usrp1.i:

  int read_aux_adc (int which_dboard, int which_adc);
