The eCos configuration I have appears to have the networking package included and yet when I attempt to link my application against the eCos libs I get several 'undefined reference' type errors.  In particular:

It doesn't look like the network has been configured.

What eCos sources are you using (latest from anon CVS is recommended)
Can you send your actual configuration? (use File->Export)

Also, you probably should be using the FreeBSD network stack
as the OpenBSD stack is very old and no longer maintained.
