sys/netinet6 : icmp6.c nd6.c nd6.h nd6_nbr.c
Log message:
Remove upper layer neighbor reachability hints.
Running neighbor discovery once in a while is better than touching the
neighbor cache for (nearly) every TCP packet.
This functionality was disabled by default, however due to a bug /
missing optimization, the code did a bunch of work before figuring out
that the feature is disabled.
With this, net.inet6.icmp6.nd6_maxnudhint can be removed.
OK bluhm
