sys/netinet : ip_icmp.c
sys/netinet6 : icmp6.c
icmp_mtudisc() might be called by TCP even on loopback after a
retransmit timeout. Do not run path MTU discovery on local routes
as we never want that on loopback. For permanent ARP or ND entries
disable path MTU discovery as they use the same rt_expire field.
This prevents that permanent routes and entries disappear.
