Sun Managers:

Thanks for all the replies:

There is a doc in the answerbook for Ultra h/w setup describing the
parameters to set for full duplex operation:

1) Driver dependent config (/kernel/drv/hme.conf):
-- ------ --------- ------ -----------------------
adv_autoneg_cap = 0 adv_100fdx_cap = 1 adv_100hdx_cap = 0 adv_10fdx_cap = 0
adv_10hdx_cap = 0;

2) /etc/system config:
-- ----------- -------
* Begin hme - force 100BaseTX - Full Duplex Mode
set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_100fdx_cap=1
* End hme

3) ndd config setting:
-- --- ------ --------
ndd -set /dev/hme adv_autoneg_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_100fdx_cap 1

So far I have had no problems using Full Duplex 100BaseTX mode on my
Ultra Creator 1 with Bay's 28115ADV 10/100 switch, agent software
version 2.012.

How to check what mode and speed a hme adpater is current running at:
---------------------------------------------------------------------
sunbay:/# ndd /dev/hme link_speed
1 1 - 100MB/sec
sunbay:/# ndd /dev/hme link_mode
1 1 - Full Duplex Mode

Note: When you do a 'netstat -i' you should notice that the collision
      count should be zero...
