How determine DVB-S2 card?

[Ali H.M. Hoseini]

Dear Jan-Benedict,

Could you kindly send your complete fe.c, or a patch of it against
getstream in git?
I tried to merge your code in fe.c, but I'm not a c programmer, and it
seems your code section is different from getstream in git.

Best regards.
Ali.
