I am using SPI1 with the HDMI ports disabled.  D0 is mapping to pin 7 (SDO) and D1 is mapping to pin 5 (SDI), P9.31 the clock goes to pin 6 and P9.28 goes to pin 8.

Mailinglist changed to [0].

Please let me know which kernel, libnl3 and lowpan-tools version do you
use.

Also I need to notice you that I am working on a big rework. With new
userspace tools, etc... I need some time to bring it mainline. The bring
it mainline thing is currently in progress.

I am very busy right now.
