this modifies the stv0900 src so that when you tune a freq ( FE_SET_PROPERTY ) that when it does it's little adjustments, it saves those settings in the same u.data variables you used to tune with, that way when you do a FE_GET_PROPERTY you can actually pull the info.

the Prof 7500 search +/-5mhz for the signal, and +/-10000 SR, does auto system (dvb-s/dvb-s2/dss), auto modulation (qpsk/8psk), auto pilot, auto rolloff, auto inversion, and auto fec.

so you can put in super generic tuning info, then do a FE_GET_PROPERTY and pull all the specifics out so you can use it in your other tuners that dont do all that fancy stuff.
