Some (North American) providers use a non-standard mode called "8psk turbo fec". Since there is no flag in the driver that would allow an application to determine whether a particular device can handle "turbo fec", the attached patch introduces FE_CAN_TURBO_FEC. Since there is no flag in the SI data that would indicate that a transponder uses "turbo fec", VDR will assume that all 8psk transponders on DVB-S use "turbo fec".
