From: Klaus Schmidinger Date: Thu, 1 Jul 2010 04:37:34 +0000 (-0300) Subject: V4L/DVB: Add FE_CAN_TURBO_FEC X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f6a20eb1a2d35660240cd1eb8dc2bd6504a0c6c5;p=openwrt%2Fstaging%2Fblogic.git V4L/DVB: Add FE_CAN_TURBO_FEC 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".
