NOOOOOOOOOOO!!

Not another one.  STOP STOP STOP.

After 100's of complaints on how TSM is 'slow' cause by this issue i've
had just about enough of the incorrect statements that auto-negotiate
doesn't work, yes, it had problems in 1997, when vendors sold devices
that were not IEEE 802.3 compliant.  This problem now is usually someone
either on the network switch side or host network card is abritraily
hard coding without checking this setting on both the switch or server.
