Without adding the patch 0103-MIPS-OWRTDTB.patch, I got an error:

WARNING: kmod-6lowpan-iphc is not available in the kernel config -
generating empty package


ERROR: module '/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-'
is missing.

This is about a package I added in menuconfig but I need them. Those
package worked well while compiling with Linux 3.18. Any idea?

Varka, which configuration did you use? Only the minimal? (I mean set
Target and Subtarget in menuconfig)
