2020-04-06	ipv6: rpl: fix loop iteration	Alexander Aring
	This patch fix the loop iteration by not walking over the last iteration. The cmpri compressing value exempt the last segment. As the code shows the last iteration will be overwritten by cmpre value handling which is for the last segment. I think this doesn't end in any bufferoverflows because we work on worst case temporary buffer sizes but it ends in not best compression settings in some cases.

2020-03-29	net: ipv6: add support for rpl sr exthdr	Alexander Aring
	This patch adds rpl source routing receive handling. Everything works only if sysconf "rpl_seg_enabled" and source routing is enabled. Mostly the same behaviour as IPv6 segmentation routing. To handle compression and uncompression a rpl.c file is created which contains the necessary functionality. The receive handling will also care about IPv6 encapsulated so far it's specified as possible nexthdr in RFC 6554. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S.
