Doc: Refer to ip-sysctl.txt for strict vs. loose rp_filter mode
Jesper Dangaard Brouer [Mon, 23 Feb 2009 04:40:43 +0000 (04:40 +0000)]
The IP_ADVANCED_ROUTER Kconfig describes the rp_filter
proc option.  Recent changes added a loose mode.
Instead of documenting this change too places, refer to
the document describing it:
 Documentation/networking/ip-sysctl.txt

I'm considering moving the rp_filter description away
from the Kconfig file into ip-sysctl.txt.
