IPT_RETURN is not worked in the kernel 2.6.10

[Vincent]

Sorry, after understanding the meaning of ipt_do_table function. I know
currently the IPT_RETURN is only available in the standard target.=20
But I wonder why don't we have the IPT_RETURN in the user defined
target?=20
Can we create a IPT_RETURN in the user defined target. So that we can
use the IPT_RETURN in our target to return to the upper chain.

What I mean is "can we port the IPT_RETURN to the user defined target in
the ipt_do_table function?"
