[ECOS] How to configure MPC8260 ethernet in Redboot

How to configure MPC8260 ethernet in Redboot via eCos Configuration Tool?

I select 'Motorola MPC8260 VADS board' in Hardware and Packages is 'redboot' to build myself boot image.

If I want to add network function to download something like configuration file and run-time image automatically during booting phase:
1) Need I add 'FreeBSD network stack' package?
2) Why item 'MPC8260FEC ethernet driver' is gray and not configureable?
3) Or Any others packages are necessary.

Thank you!
