Hi, Launois.

In the following case, while ipt_ROUTE action, which is
the ipt_route_target(), is processing, another netfiter action is called.
Is it able to call one netfiter action during processing another one?

ROUTE action is called when PRE_ROUTING rule is matched, after
that, in the PRE_ROUTING action, OUTPUT and POST_ROUTING
is called. so, nf_hook_slow() is nested.

Is that ok??

thanks for your advice.
