	Hello All ,  I am having a dickens of a time with auto negotiation
	between a netgear fsm726s & a TrendNet TEG-PCISX+ .  Fyi ,  Which
	I bought just for this card .

	The switch reports negotiating ...
	Port Name        Link On/Off State      Rate/Duplex Flow Ctrl
	26GB Not Defined Up   On     Forwarding (10   Full) (Disabled)

	ns83820 reports ,  eth0: link now 1000F mbps, full duplex and up.

	The thruput to a 10/100 device is dismal at best .  Which
	lead me to the idea that something was wrong with negotiation .
	See (*) below .

	I have attempted to set the switch port speed/duplex/flow manually
	then I am unable to ping thru the ns83820 card .

	I am quite aware that this could well be a difficulty in the
	switch still .  So I am looking for pointers on where to look ?
 	I already tried the netgear suport site ;-} .  That is why I am
	running the lastest code for the switch (1.0.4) .
