sys/netinet6 : nd6.c nd6.h
Log message:
Use a single timer for all ND6 entries.
This prevents a use-after-free reported by Hrvoje Popovski where the
timeout function was already sleeping on the NET_LOCK() when ifconfig(8)
removed the enry from the table.
By iterating on a global list in the timeout routine we ensure that the
items are still valid when we process them. This also reduce differences
with ARP.
