This patch series fixes the fragmentation implementation according to rfc4944. So ping (with fragmentation) to contiki(or other rfc4944 compatible 6lowpan stacks) comes possible.
I wanted to made a fragmentation implementation with the internal fragmentation api(include/net/inet_frag.h). The current desgin/architecture of the 6lowpan stack doesn't let me use this api right now. So I fix the current implementation for fragmentation. I am working to change the desgin/architecture to use the internal fragmentation api. It also fixes the udp uncompression/compression implementation and other issues which I detected while testing. Changes since v2: - add race condition patches - hold fraglist lock while accessing list in timer expire function. - use try_to_del_timer_sync for a special case of race condition. - split udp fix in several small fixes, so it's easier to review. - change commit msgs issues which are reported from Werner (thanks). Added also a sentence for the other magic number. - fix use of new skb_mac_header and skb_network_header - small changes on commit msgs.
