parentdecnet: Convert to use flowidn where applicable. (diff)
ipv4: Fix PMTU update.
On current net-next-2.6, when Linux receives ICMP Type: 3, Code: 4 (Destination unreachable (Fragmentation needed)), icmp_unreach -> ip_rt_frag_needed (peer->pmtu_expires is set here) -> tcp_v4_err -> do_pmtu_discovery -> ip_rt_update_pmtu (peer->pmtu_expires is already set, so check_peer_pmtu is skipped.) -> check_peer_pmtu check_peer_pmtu is skipped and MTU is not updated. To fix this, let check_peer_pmtu execute unconditionally. And some minor fixes 1) Avoid potential peer->pmtu_expires set to be zero. 2) In check_peer_pmtu, argument of time_before is reversed. 3) check_peer_pmtu expects peer->pmtu_orig is initialized as zero, but not initialized.
