2011-11-03staging: Move media drivers to staging/mediaMauro Carvalho Chehab
In practice, it is being hard to distinguish when a patch should go to staging tree or to the media tree. Better to distinguish it, by putting the media drivers at a separate staging directory. Newer staging drivers that include anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should go to the drivers/staging/media tree.

2011-11-03[media] staging: as102: Unconditionally compile code dependent on DVB_CORESylwester Nawrocki
The driver depends on DVB_CORE so there is no need for conditional compilation of parts of the code depending on CONFIG_DVB_CORE as the driver is never compiled with CONFIG_DVB_CORE* disabled.

Add support for the Elgato EyeTV DTT Deluxe. Note that the product name field has not yet been abstracted out, so it will still identify itself as a PCTV 74e. The driver was originally built by the chipset manufacturer so that the product vendor can specify the device name via a #define, but wasn't setup to support multiple products from the same build of the driver.

2011-11-03[media] staging: as102: Initial import from AbilisPierrick Hascoet
Changes by Devin Heitmueller: Import the original Abilis Systems as102 driver. The source is unmodified, with the only changes I've made so far were that I created a Kconfig and Makefile so that the code builds in a standard v4l-dvb tree. This driver requires firmware (which Abilis has provided with redistribution terms which will allow it to be bundled in the Linux distributions). The firmware can be downloaded from here: Thanks to Rainer Miethling from PCTV Systems for working to get the driver released (for use with the PCTV 74e) and Pierrick Hascoet from Abilis for authoring the driver.

2011-11-02ixgbe: DCB, return max for IEEE traffic classesJohn Fastabend
Returning the max traffic classes on get requests simplifies user space configurations because applications will know explicitly how many traffic classes can be used. Typical switch implementations use 2 or 3 traffic classes so this not seen often today. And user space can learn the number of traffic classes by return codes but this allows user space to configure ixgbe correctly at the start.
