Yuchung Cheng 2d2517ee31 tcp: fix reordering SNMP under-counting ... Currently the reordering SNMP counters only increase if a connection sees a higher degree then it has previously seen. It ignores if the reordering degree is not greater than the default system threshold. This significantly under-counts the number of reordering events and falsely convey that reordering is rare on the network. This patch properly and faithfully records the number of reordering events detected by the TCP stack, just like the comment says "this exciting event is worth to be remembered". Note that even so TCP still under-estimate the actual reordering events because TCP requires TS options or certain packet sequences to detect reordering (i.e. ACKing never-retransmitted sequence in recovery or disordered state).
