Header compression is applied by the node that transmits on the 6LoWPAN adapter. So it makes sense to always try these ports even if the current device has no 6LoWPAN interfaces. But like I said, it might be best to come up with a Linux kernel feature to suggest these ports and let it do the finding of the free one available. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
