2015-11-25sd-ndisc: better validate RA packetsTom Gundersen
Verify the hoplimit and that the received packet is large enough for the RA header. See <http://tools.ietf.org/html/rfc4861#section-6.1.2>.
2015-11-25sd-ndisc: always send the link-layer addressTom Gundersen
We never send packets without first knowing the link-local L3 address, so we should always include the L2 address in RS packets.

There are more than enough to deserve their own .c file, hence move them over.
