Subject: V4L/DVB: Add FE_CAN_TURBO_FEC
Author:  Klaus Schmidinger <[email protected]>
Date:    Thu Jul 1 01:37:34 2010 -0300

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".
