I want to see currently discovered Path MTU.
I tried netstat -rnaW, but it doesn't show any cloned routes, but i clearly
see Path MTU discovery working, by watching tcpdump tracing. An application
sends full sized packet with DF bit, receives ICMP Unreach Frag message and
retransmits downsized packet again.
I need this, because there is another 6.2-RELEASE-p3 host, which doesn't
perfom Path MTU discovery, although:
# sysctl -a | grep path_mtu
I tried disabling firewall, simplifying routing, but none helps.
