not, we cannot form a proper vxWorks bootline at this place.
So we move to the way, forming the bootline just before executing/launching vxWorks with "go <address>". At this time we have a valid IP-setup for sure because it is either in environment or defined through CONFIG_PREBOOT command.
To do this, we overload the __weak function "do_go_exec(...)" with our own and do the job.

I don't understand the technical details here on this board, but can we use the generic 'bootvx' command to handle the VxWorks bootline?
At first i had a look to this, but unfortunately it is not useable for my case, because we are passing serveral things more through the bootline to our vxWorks kernel. Especially o=... contains several information like framebuffer address, factory-settings address and so on. Further we have FTP-Filesystem, so we pass additional arguments ( u=vxWorksFTP pw=vxWorks).
