once you have got it (say some 001094c)

2.Download the driver from this site(say ur driver is ife0)
http://homepage2.nifty.com/mrym3/taiyodo/eng/

5.#mv Makefile.amd64_gcc Makefile

6.#ln -s amd64 obj

7.#export PATH=/usr/ccs/bin/:PATH  //append make command to the path

or else you can also use

#/usr/ccs/bin/make

8.#make install //if you have set the path or else /usr/ccs/bin/make

9.#./addrv.sh

10.#modload ife

11.#ifconfig ife0 plumb

12.#ifconfig -a   //if ife0 driver is installed then in the output you will find it

13.#echo "192.168.1.1" > /etc/defaultrouter

14.#echo "nameserver 8.8.8.8" > /etc/resolv.conf

15.#touch /etc/dhcp.ife0

16.#ifconfig ife0 dhcp start
