For those who are interested, here is the information that I received.  Much
thanks to all of those who replied:
	Aaron Hirsch
	Chris Price
	Bob Cummings
	John Riddoch

Look for Infodoc # 41665

>From the FAQ section:
2.How do I see the actual Operational Mode settings ? 
  Check link_ parameters of netstat -k ce[your_interface.number]
     link_up - 0 down, 1 up 
     link_speed - speed in Mbit/s 
     link_duplex - 1 half duplex, 2 full duplex, 0 down
  This parameters must show the same values on both sides.
  If not, Autonegotiation does not work. 
You'll have to set for both cards if you want to get them both to 100/FD.
For example, here's what I set for a QFE card in a server:
	for i in 0 1 2 3; do
	  ndd -set /dev/qfe instance $i
	  ndd -set /dev/qfe adv_100T4_cap 0
	  ndd -set /dev/qfe adv_100fdx_cap 1
	  ndd -set /dev/qfe adv_100hdx_cap 0
	  ndd -set /dev/qfe adv_10fdx_cap 0
	  ndd -set /dev/qfe adv_10hdx_cap 0
	  ndd -set /dev/qfe adv_autoneg_cap 0
Alternatively, if you set it in /etc/system, it should carry for all cards.
Did you turn off gigabit capability for the devices (ce0,ce1)? That one
stumped me for a few days.

Thanks again,
