Runtime dependand help doesn't look sane. Help should always show all
possible options/command while trying to use unsupported option should
display error message.

That makes sense. But don't complain to me about the quality
of the error messages afterwards please :)

I applied a variant of Patrick's original patch. I added text for delete,
and avoided some code movement.  The help text should only show what is
supported otherwise there will be user complaints.

Too bad. 

Help should show all options while trying to use unsupported ones should 
yeld "unsupported"/some error message.

Will ipv6 options etc, etc also be hidden when ipv6 not available?

The options won't show on older kernels. It is not a kernel config option
difference, it is old legacy code, like back to 2.4 where the API's just
aren't there.
