2015-09-17ieee820154: 6lowpan: dispatch evaluation reworkAlexander Aring1-1/+12
This patch complete reworks the evaluation of 6lowpan dispatch value by introducing a receive handler mechanism for each dispatch value. A list of changes: - Doing uncompression on-the-fly when FRAG1 is received, this require some special handling for 802.15.4 lltype in generic 6lowpan branch for setting the payload length correct. - Fix dispatch mask for fragmentation. - Add IPv6 dispatch evaluation for FRAG1. - Add skb_unshare for dispatch which might manipulate the skb data buffer.
