The current 6LoWPAN udp compression/uncompression is completely broken. This patch series fix a lot of udp compression/uncompression issues and add support parsing with lowpan_fetch_skb/lowpan_push_hc_data functions.
I tested it in all cases of compressions in wireshark and a contiki sensornode. Changes since v3: - add patch to introduce lowpan_push_hc_data helper function. - remove patch to fix nullpointer dereferencing and replace it with a patch which use the lowpan_push_hc_data function in compress_udp_header function. This fixes the nullpointer dereferencing problem also and is more readable. - add missing newline in pr_debug_ratelimited. Changes since v2: - remove unnecessary casts and brackes, suggested by Werner Almesberger. - use pr_debug_ratelimited instead of pr_debug on patch 4/7.
