The responses arrived so quickly...thank you.

To manually set the speed on an auto-sensing nic card you can use the
following command:

ndd -set /dev/hme adv_autoneg_cap 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_100fdx_cap 1

Make sure that the port on the switch is also set to 100Mb Full-duplex
if you sed the adv_100fdx_cap to 1. If you want 100Mb Half-duplex, set
adv_100hdx_cap 1 and adv_100fdx_cap 0.

Thanks to:
