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) .
