Assuming you NIC is hme

 ndd -get /dev/hme link_speed (speed)
 ndd -get /dev/hme link_mode (full / half duplex)

To set it to 100 FD
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_100T4_cap 0
ndd -set /dev/hme adv_100fdx_cap 1
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0

first try to find out which NIC is up on your system,
ifconfig -a

then check the NIC with up entry,
and then u can try liddler suggestion for finding out speed for that NIC.

thats the first one. u may  be root to get this value.
also check
#ls -l /dev/iprb1
it must be some sym link
ls -l that sym link too.

For shure!
But the error message indicates other problems too, see shivsa's comment.

> .. explain me the meaning of each ndd -set options ..
see your question? Or issue
  ndd options /dev/iprb1
if still in doubt:
  man ndd

You should not use the 1
try
/usr/sbin/ndd -get /dev/iprb link_speed
-------------------------------^-----------
instead of
/usr/sbin/ndd -get /dev/iprb1 link_speed
