But for compression, since we don't > have some interface to make this configurable we should use RFC 6282. So I will ensure UDP is compressed by 6282. Then I was going to start out by just compressing ICMPv6 with GHC and monitor how much data is saved by using GHC. Later on we will implement a mechanism of configuring what gets compressed and by which compression method. The GHC spec states that a device indicates it's GHC capability using a 6LoWPAN Capability Indication Option (6CIO), this is an ND option. As far as I can see there is no type assigned yet by IANA so I was wondering if we should have this as an experimental configuration item in the kernel? > > Same opinion here?
