I'd be interested in peoples comments on the analysis that now
turns up with ``set log +lqm''.  My only real-world testing has
been with my ADSL provider, and with output such as:

LQM: ADSL: Input:
LQM:   Magic:          22264bc4   LastOutLQRs:    00000011
LQM:   LastOutPackets: 0000267d   LastOutOctets:  00ba1202
LQM:   PeerInLQRs:     00000010   PeerInPackets:  02f31620
LQM:   PeerInDiscards: 00000000   PeerInErrors:   00000000
LQM:   PeerInOctets:   bc00380e   PeerOutLQRs:    00000010
LQM:   PeerOutPackets: 4348204d   PeerOutOctets:  4441502f
[.....]
LQM: ADSL: Input:
LQM:   Magic:          22264bc4   LastOutLQRs:    00000012
LQM:   LastOutPackets: 00002a91   LastOutOctets:  00ce7585
LQM:   PeerInLQRs:     00000011   PeerInPackets:  02f31a34
LQM:   PeerInDiscards: 00000000   PeerInErrors:   00000000
LQM:   PeerInOctets:   bc14a3b9   PeerOutLQRs:    00000011
LQM:   PeerOutPackets: 00000000   PeerOutOctets:  00004545
LQM: Analysis:
LQM:   Outbound lossage: 0 LQRs (0 en route), 0 packets, -2088 octets
LQM:   Inbound lossage: -1128801017 packets, -1145157573 octets
LQM:                    Likely due to transport congestion

I can only blame their implementation -- believe me, those
PeerOutPackets/Octets are not for real!!!  Perhaps they're
including some L2TP header info or something with their
PeerInOctets value...

Cheers.
