This patch series introduce the next header compression framework. Currently we support udp compression/uncompression only. This framework allow to add new next header compression formats easily. If somebody wants to add a new header compression format and some information are missing while calling compression and uncompression callbacks. Please feel free to make framework changes according these callbacks. Note: If building 6lowpan_udp as module please make sure it's loaded before running rfc6282 udp connection. If it's not loaded we send 6lowpan with raw udp header and next header compression bit isn't set. Nevertheless if you use rfc6282 connection and 6lowpan_udp isn't loaded following will be printed: "ieee802154 wpan-phy0 wpan0: received nhc which is not supported. Dropping." changes since v2: - make udp nhc as module as suggested by Marcel Holtmann - fix comment header in nhc_udp.c I didn't make the lowpan_nhc declaration "const" because this will occur issues with rb_node, id and idmask array. Which will manipulated during runtime.
