This very interesting and informative reply came from Jenny Butler (Thanks
Jenny!):
Andy,  I set up a system with a gigabit NIC about 1 1/2 years ago.
I too tried to find a setting without any luck.  I asked the Customer
Support Center for Tru64 UNIX networking and here's what they
said to me:
It's not necessary to set the speed at the console or in rc.config, since
the gigabit adapters only support one speed:  1000meg full duplex.  When
the driver loads it will attempt to establish a link with the switch at
this speed.  We can configure the address with an IFCONFIG in rc.config:
NETDEV_0="alt0"
export NETDEV_0
IFCONFIG_0="xx.xx.xx.xx netmask xx.xx.xx.xx"
export IFCONFIG_0
I did what they said - did not set a speed, and it worked fine.  In my
/var/adm/syslog.dated/*/kern.log - after rebooting the system, I can
see the correct info as shown here:
Sep  3 09:09:37 sysname vmunix: alt0: 1000 Mbps full duplex Link Up via
autonegotiation
Hope this helps!  Jenny
