From: Klaus Schmidinger Date: Wed, 31 Dec 2008 17:11:23 +0000 (-0300) Subject: V4L/DVB (10164): Add missing S2 caps flag to S2API X-Git-Tag: v2.6.29-rc1~523^2~8 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=cb889a2f3515b140bef193cf6ffcdb099349b8aa;p=linux-2.6-omap-h63xx.git V4L/DVB (10164): Add missing S2 caps flag to S2API The attached patch adds a capability flag that allows an application to determine whether a particular device can handle "second generation modulation" transponders. This is necessary in order for applications to be able to decide which device to use for a given channel in a multi device environment, where DVB-S and DVB-S2 devices are mixed. It is assumed that a device capable of handling "second generation modulation" can implicitly handle "first generation modulation". The flag is not named anything with DVBS2 in order to allow its use with future DVBT2 devices as well (should they ever come).
