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. 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. changes since v3: - add patch 3/3 for other known rfc6282 ipv6 extension headers compression formats - add request_modules for loading nhc default compression format modules. Which was suggested by Jukka Rissanen. Thanks, this is really working. - Add rtnl_lock for lowpan_nhc_add and del since we have no synced request_modules call this could make trouble. - Move some handling out of nhc_do_compression and uncompression function. The complete handling is now inside of iphc.c and nhc_do_compression and uncompression functions is only a wrapper call for the callback. - rework some menuentries for Kconfig and compression format, they are grouped by rfc now. - move some generic handling like "skb_pull(skb, nhc->nexthdrlen);" into iphc.c. It would be great if we have something also for uncompression for the skb_cow. But this isn't possible right now. - change warning if nhc was not found to "was not found" instead isn't implemented. It isn't implemented if callbacks are NULL now. - small cleanups.
