I think I was a bit mistaken though. I didn't catch that this line was itself in a patch file: +# CONFIG_FEC_NAPI is not set I also didn't catch and don't quite understand how the defconfig file is applied in the build process. Is 'nitrogen6x_defconfig' even used? I don't see CONFIG_FEC in the defconfig. Does that file somehow get applied on top of a base configuration to apply Yocto specifics? There are some things in our boundary-L3.0.35_12.09.01_GA tree that I was hoping to clean up before submitting In particular, we set things up to allow a single image to boot on Quad->Solo that the Freescale team didn't like, so we'll probably revert it as we migrate to the 2012-10 branch, which will take a couple of weeks. I'm not really sure how to proceed. Please advise, Eric
